Many people don’t realize there are two types of expansion. Downward expansion is a popular choice for minimizing low-level noise like hiss and hum. It’s the opposite of a compressor: compression progressively reduces the output level above a certain threshold, while a downward expander progressively reduces the output level below a certain threshold. For example, with 2:1 compression, a 2 dB input level increase above the threshold yields a 1 dB increase at the output. With 1:2 expansion, a 1 dB input level decrease below the threshold yields 2 dB of attenuation at the output.

Upward expansion doesn’t alter the signal’s linearity below the threshold—if the input changes by 2 dB, the output changes by 2 dB. But above the threshold, levels increase. For example, with 1:2 expansion, a 1 dB increase above the threshold becomes 2 dB of increase at the output. Fig. 1 shows the difference between downward and upward expansion.

Figure 1: The top screen shot shows how downward expansion attenuates levels below a threshold, while the lower one shows how upward expansion increases levels above a threshold.

That’s Nice…So What?

Upward expansion is a useful tool for drums, hand percussion, and other percussive instruments. One function is transient shaping, to emphasize attacks. Suppose you have a drum loop with too much room sound. Traditional expansion can make the room sound decay faster, but using upward expansion brings the peaks above the room sound, while leaving the characteristic room sound alone.

Another use is with percussion parts, like hand percussion, that are playing along with drums. A lot of times you don’t want the percussion hits to be too uniform in level, but instead, the most important hits should be a little louder compared to the rest of the part. Again, that’s where upward expansion shines. Dip the threshold just a tiny bit below the peaks—the peaks will stand out, and sound more dynamic.

Let’s listen to an audio example. The first two measures use no upward expansion with a drum track. The next two measures add a subtle amount of upward expansion. You’ll hear that the peaks from the kick and snare are still prominent, but the room sound and cymbals are a bit lower by comparison. The final two measures use the settings shown in Fig. 2. The kick and snare peaks are still there, but the rest of the part is more subdued, and the overall sound is “tighter,” with more dynamics.

Figure 2: Expander settings for the Upward Expansion Demo.

The only difference among the two-measure sections is the Range control setting. For the first two measures, it’s 0.00 dB; nothing can be above the threshold, because there is no threshold. In the second two measures, the Range is -2.00, so anything above that threshold goes through 1:4 expansion. In the final two measures, the range is -4.00 (I rarely take it lower, as long as the Event hits close to 0 on peaks).

Here’s the coolest part: Automating the Range parameter lets you alter a drum part’s dynamics and feel, without having to change the part itself. This is particular wonderful for compressed drum loops, because you can lower the range to keep the peaks, while making the rest of the loop less prominent. When you want a big sound, slam the Range back up to 0.00.

But Wait! There’s More!

The Multiband Dynamics processor can do frequency-selective upward expansion. You can isolate just the high frequencies where a drum stick hits, and emphasize only that frequency. Another use is making acoustic guitars sound more percussive, as in this audio example.

The first two measures are the original acoustic guitar track, and the next two use Multiband Dynamics to accent the strums (Fig. 3).

Figure 3: This setup takes advantage of the Multiband Dynamics’ ability to add upward expansion to a specific frequency range. Note the Input level control adding gain (outlined in white).

The Multiband Dynamics are in a separate, parallel track (you could build this into an FX Chain, but I think showing this in two channels illustrates the process better). Because the Multiband Dynamics is listening to only the high frequencies, which are quite weak and not sufficient to go over the expander threshold, the Input control is adding +10 dB of gain. Alternately, you could insert a Mixtool before the Multiband Dynamics.

This effect is best when used subtly, but next time you want to reach for a transient shaper, try this instead. It’s a flexible way to emphasize percussive hits and strums.

There are many uses for alternate mixes, and Studio One makes it not only easy to create alternate mixes, but also to store them as part of a song. We’ll cover traditional uses for alternate mixes, and then get into some more unusual applications.

How to Create and Store Alternate Mixes

When sending a file off for mastering, sometimes the engineer will want two additional versions, one with the vocal up 1 dB and another with it down 1 dB. This is because during the course of mastering, the relationship of the vocal to the track might change. A more prosaic example is creating a mix without vocals for karaoke, and of course, remixes are common in EDM. You might also do an “unplugged” version with only the acoustic tracks.

After creating the alternate mix:

1. Choose Song > Export Mixdown (Fig. 1).

Figure 1: The Export Mixdown dialog box. Note that Import to track (outlined in white) is checked to bring the exported file into the song.

2. Choose a location for the mix, the export range, file resolution, and make sure you check Import to track. (If while exporting a warning says there was clipping, reduce the master fader to compensate—for example if the export was 1 dB over 0, reduce the master fader level by at least 1 dB.)
3. The file will now appear as a track within your song. When you save the song, you’ll save the alternate mix.

If your mix changes are relatively extensive, save it as a Version so you can recall it later. Choose File > Save New Version, and name it (Fig. 2). Use a name that corresponds to the name of the alternate mix file, and then you can choose File > Restore Version to recall the version corresponding to that particular mix.

Figure 2: It’s easy to save a version of a song that corresponds to a particular alternate mix.

Processing Song Sections with Alternate Mixes

Suppose you want to add flanging to only a solo section of a song. You can insert a flanger in the main bus, and then adjust automation to enable it and set the parameters as desired. However, another option is to create a mix, and bring it into your song as a track. Then, create an alternate mix you bring into the song. Now you can experiment on the alternate mix with the effect(s) you want to use, and when you have the sound you want, render it. Cut the solo section you want to flange from the main mix, and insert the rendered solo section from the alternate mix.

Better Virtual Instrument and Amp Sim Feel

Last week’s tip covered how to save CPU power with amp sims by bouncing and/or transforming the track with the sim. One user commented “I can see how doing [this] reduces CPU load, but only after I’ve finished choosing and using an amp sim patch. My frustration is the latency or CPU hit when actually playing my guitar through an amp sim, deciding on what I’m going to play, rehearsing it, auditioning amp sim patches and so on.” Alternate mixes to the rescue: make a premix of all tracks except the one with the amp sim, and then disable the tracks themselves. With the tracks now placing no load on the CPU because you’re listening only to the premix, you can throttle the latency way down when playing around with your sim and adding a new part. After recording the part, you can use the tips presented last week to reduce the CPU drawn by the amp sim.

Auditioning Different Mixes for Albums

The renewed interest in vinyl has had a corollary effect: an interest in albums and collections of songs, not just singles. As a result, Studio One’s synergy between the Song and Project page—where you can edit songs after hearing them in context with the master file, and update the master file with that song’s changes—is brilliant. But even if you don’t produce albums, Studio One’s mastering options make it easy to obtain consistency among songs. That way, if someone switches from one song of yours to another on YouTube or Spotify, there won’t be a jarring difference.

But you might do various mixes of songs, so you can choose the best one when assembling an album. If you update the version in the mastering file after changing a mix, to compare it to a previous mix you need to open the file with the other mix (which may take a fair amount of time if you have lots of effects and virtual instruments), update the mastering version, and repeat with any other mixes.

A simpler option is to create alternate mixes in your song as described above (remember to save each alternate mix as a separate version), and mute all tracks in the song except for the track with the mix you want to audition. Update the mastering file with that track. To audition a different mix, mute all tracks except for the different mix, update the mastering file, and hear that mix in context. Once you decide which mix you like best, open the Version containing that mix, and then you can make further tweaks to it.

There’s an old joke about guitarists:

“How many guitars does a guitar player need?”

“Just one more!”

…and sometimes I feel the same way about amp sims, because all of them are different. Ampire XT benefits from PreSonus’s “State Space” technology, and if you have no other amp sims, its collection of amps has pretty much all the essentials.

What’s more, you can load thrid-party cabinet impulse responses (IRs) that re-create the sound of various cabinets, mics, and mic positions. These go into the User Cabinet, whose unique feature compared to typical IR loaders is being able to load individual IRs for the three mics.

But you can take impulses even further by turning off an amp’s cabinet altogether, and following Ampire XT with the Open Air convolution processor.  Although most people probably think of Open Air as a way to create a variety of reverb and other space-based effects, it’s also a flexible impulse response loader that plays nice with cabinet impulses.

There are many free cabinet impulses on the web to get you started. Admittedly, the sound quality varies—some are fine, some aren’t, but there’s also a middle ground where tweaking the Open Air controls can give the sound you want. http://cabs.kalthallen.de is a popular source for free impulses (click on the Free tab), but there are many other companies that offer free samples, or sell impulses commercially.

The Setup

Create an FX Chain with Ampire XT followed by Open Air. The Impulse Responses are only for cabinets, so set up Ampire XT’s amp and effects however you want, but turn off the cabinet section (Fig. 1).

Figure 1: Click the cabinet bypass button (middle left, outlined in white) and the cabinet field will show None (upper right, outlined in white).

Follow Ampire XT with the Open Air, and start with its Default preset. Drag an impulse into the Open Air waveform display window (or click on the impulse name field to open the file selector, and then navigate to the impulse you want). Turn Mix to 100% so that you hear only the cabinet output, and none of the pre-cabinet amp sound (Fig. 2).

Figure 2: Make sure you set the Open Air Mix control to 100%, so that you don’t hear the pre-cabinet amp sound.

 Tweaking the Tone

The Kalthallen impulse shown in the screenshot above didn’t need tweaking to sound good, but you’ll find that with a lot of the free impulse responses, you’ll need to tweak the Gain and Frequency controls. Often the main problem is a “thin” sound and Fig. 3 shows some tweaks that help remedy this issue—pull back on the highs, and boost the low end for a bigger, beefier tone.

Figure 3: These EQ settings can help tame free impulse responses that sound too thin.

But the most dramatic tweaks come by enabling Shorten with Stretch and Stretch with Pitch, then varying the Length control. This can produce sounds that are similar to different mikings, or even cab sounds you’ve never heard before. The Predelay, ER/LR-Xover, and ER/LR controls can also affect the sound, although the differences aren’t as dramatic as stretching with the Length control.

Finally, although it’s great to have options, you don’t want to suffer from option overload (“maybe trying just one more impulse will give the sound I want…”). If you download a bunch of impulses, create a folder of favorites in a place where it’s easy to open it up, and drag-and-drop impulses into Open Air. If you find one you really like, save it as an Open Air preset for future use.

There are a lot of filter responses: notch, bandpass, peak, allpass, high pass, lowpass, shelf…now let’s add the “table” response to the collection.

Parametric EQs can add peaks and cuts that are broad, narrow, or anywhere in between, but they all have slopes on either side of the filter frequency. The table response described here can boost or cut over a range of frequencies, with a flat response over that range. This avoids having to dedicate several overlapping parametric stages, which still doesn’t achieve quite the same result. The key to this response is combining shelving EQs.

Table Response Boost

To boost a frequency range, set the low- and high-shelf frequencies to the lowest and highest frequencies in the range (Fig. 1). Use the Shelf setting to determine how quickly the boosted section returns to the flat response. I’ve found the 12 and 24 dB settings works well, because the Q control comes into play. This can provide additional modifications to the response, which we’ll cover later. However, for the gentlest effect, 6 dB is valid in many situations as well.

Figure 1: This table response, inserted before a high-distortion amp sim, gives greater sensitivity to midrange notes and also trims the highs and lows for a “tighter” sound.

But we’re not done quite yet. To provide an actual boost, increase the output Gain control for the desired amount of boost. For example, if you want the table response to boost +12 dB, set the high and low shelf Gain settings to -12 dB, and the output Gain control to +12.

Table Response Cut

Similarly to the boost option, set the low- and high-shelf frequencies to the lowest and highest frequencies in the range you want to cut (Fig. 2). Again, use the Shelf setting to determine how quickly the boosted section returns to the flat response; the same general comments about how the shelf slope works with boosting apply here too.

Figure 2: This table response for a drum loop cuts back on the midrange a bit to help emphasize the kick and the snap/sizzle of the share and high-hats; it also reduces any “midrange mud,” and makes space in that frequency range for other instruments.

Cutting requires an equal and opposite approach to what we did for boosting. If you want the table response to cut 4 dB, then boost the shelf controls by +4 dB. Then, set the output gain control to -4 dB. This restores the shelf boosts to flat, and adds the desired amount of cut for the specified frequency range.

Using Q

When cutting with the low shelf or boosting with the high shelf, increasing resonance by turning up the Q control adds a peak just above the shelf’s corner frequency, and a dip below the corner frequency. When boosting with the low shelf or cutting with the high shelf, increasing Q adds a peak just below the shelf’s corner frequency, and a dip above the corner frequency. This emphasizes the extremes of the chosen frequency range, while also increasing the depth of the cuts near the corner frequency. Try adding resonance to the low shelf when using this technique for vocals, particularly narration (Fig. 3).

Figure 3: The table response adds a bit of a low-frequency boost (with Q) to give the “late night FM DJ sound,” but also cuts lower frequencies to reduce p-popping. Meanwhile, the high-frequency shelf emphasizes the voice’s articulation, while reducing extraneous highs, hiss, and sibilance.

Of course, the table response doesn’t replace a parametric. But sometimes, it might be just the response you need, and you’ll find it faster to dial in the right frequency range by moving the shelf controls than trying to make multiple stages of peak/boost EQ do what you want.

A physical guitar amp is more than a box with a speaker—it’s a box with a speaker being picked up by a mic in a room. Both the mic and room contribute to the overall sound. To better emulate the sound of a physical guitar amp, Ampire includes a Mic Edit Controls panel that allows making a variety of virtual mic adjustments.

Ampire doesn’t include room emulation, because you can emulate room sound with several of Studio One’s plug-ins—Room Reverb, Open Air Reverb, Mixverb, and Analog Delay. However, it’s best to avoid adding ambiance until most other tracks have been cut, so that the ambiance achieves the right balance. Too much ambiance can clutter the mix, or hog the stereo field.

The mics you choose, their levels with respect to each other, and whether you add delay can make a major difference in your amp’s sound. So, let’s investigate the Mic Edit Controls panel (Fig. 1).

Figure 1: The Mic Edit Controls in Ampire XT.

Choosing the Mic Type

Many guitarists record with their amp cranked to really high levels, to get their “sound.” Dynamic mics are ideal because they can handle high levels, and the inexpensive Shure SM57 is the classic guitar cabinet mic—many engineers choose it even when cost is no object. Although dynamic mics may lack brightness compared to condenser mics (as modeled by Mic C), this doesn’t matter much with amp cabinets, which typically don’t have much energy above 5 kHz or so anyway. Mic A in the Mic Edit Controls panel has the SM57’s sonic character, and will likely be your go-to mic.

Mic B produces the sound associated with ribbon mics, which shows one of Ampire’s benefits: older ribbon mics tended to be fragile—but you can’t blow up a virtual mic. Ribbon mics have an inherently warm midrange. Royer’s R-121 mic is popular for miking cabs, and Mic B models its overall sonic character.

Mic C emulates the PreSonus PM-2 matched pair of condenser microphones. Condenser mics are often too sensitive for close-miking loud amps, but when moved a bit back from the cab, they can give a brighter, more “open” response that handles note attacks well. They’re also commonly used as room mics, which is why these two virtual mics are arranged in an X-Y miking configuration to give a stereo image.

Wait a Minute—Did You Say Stereo?

Guitars are mono signal sources, but taking full advantage of Ampire’s mics, as well as room ambiance plug-ins, requires a stereo signal. To convert the mono guitar into a dual mono signal (i.e., stereo, but with the same audio in the left and right channels), record the guitar with the Channel Mode set to Mono (one circle showing to the right of the Record Input selector). Although this means that any plug-ins will be in mono, that’s acceptable when tracking. After recording the track, change the Channel Mode to stereo (i.e., two circles showing to the right of the Record Input selector), select the event, and bounce it to itself (ctrl+B). Now the mono guitar is dual mono.

Mic Control Applications

Each mic has three controls: level, mute button (which makes it easy to evaluate what a particular mic contributes to the overall sound), and phase switch (the Ø button). Also, Mics B and C have Delay controls.

Often when miking a physical amp with more than one mic, you’ll vary their blend to find the right mix. The Mic Mix Link button toward the extreme left simplifies this process. When enabled, altering one mic’s level adjusts the levels of the other mics oppositely.  For example, turning up Mic A turns down Mics B and C, or turning up Mic B turns down Mics A and C.

The Phase buttons and Delay controls can make major differences in the overall sound. There’s no right or wrong phase or delay setting; use whatever sounds best to you. Try the following to hear how these controls affect the sound. (Bear in mind that amp sims do a lot of calculations, so moving the controls will sound “choppy.” This is because Ampire has to recalculate constantly to reflect the changing settings.)

1. Turn off Mic Mix Link.
2. Mute Mic C.
3. Set Mic A’s Level up full, and Mic B’s Level down all the way.
4. Enable Mic Mix Link.
5. Lower Mic A’s level. Mic B’s level will increase. Note the difference in sound as the levels change.
6. Alter Mic B’s Delay time, and again, change Mic A’s level. You’ll hear a sound that’s somewhat like flanging, due to the comb filtering caused by Mic B being out of phase.
7. Enable the Phase reverse switch for Mic B, and again, alter Mic A’s level. You’ll hear a wide tonal variation.

Now check out how Mic C creates a stereo spread. With Mic Mix Link off, adjust Mic A and/or Mic B for the desired sound. Bring up Mic C’s Level control slowly, and you’ll hear the stereo image bloom. Again, the Delay control and Phase reverse button make a big difference in the sound.

Clean Sounds, Too

One of my favorite mic applications is with clean guitar sounds (cabinet only, no amp). Mic C is particularly useful, because its brightness gives the cabinet’s tone a useful lift, and creates a stereo image. Finally, note that if you change the Channel Mode from mono to stereo (or the reverse), the sound may mute. Varying one of the Mic level controls restores the sound. Of course, it’s easy enough to call up an Ampire preset, and just start playing… but becoming proficient with the Mic Edit Controls opens up a wealth of possibilities.

Our prep work is in order: in part 1 we integrated the Komplete keyboard as a DAW navigation control surface, and in part 2, explored how to create general-purpose MIDI control surface templates. In the thrilling conclusion of this trilogy (soon to be a major motion picture!), we’ll now find out how to control non-NKS instruments and effects, running within Studio One, from the Komplete keyboard hardware control surface.

BUT FIRST: FOCUS VS. GLOBAL MAPPING

Because we’ll be mapping hardware controls to software parameters, it’s important to understand the difference between Studio One’s Focus and Global control mapping functions. When you program a controller in Global mode, it affects aspects common to all songs, like faders, pan, etc. In Focus mode, you program a controller for a specific instrument or effect. Focus mode has two wonderful attributes: You can program different settings on the same instrument or effect in the same project, and Studio One remembers this assignment for other songs. For example, I made a Komplete keyboard Mojito template so whenever I call up Mojito in any song or any instance in a single song, it has a hardware control surface.

To choose Focus mode (Fig. 1), click the gear button toward an instrument or effect’s upper right. From the drop-down menu to the right of the gear symbol, choose MIDI-OX (the MIDI utility we installed back in Part 1 of the series because it lets the Komplete keyboard talk to non-NKS plug-ins). You’ll also need to choose Focus mode for an instrument or effect when you want to use a previously created template.

Figure 1: The Gear button (circled in white, upper right) opens the Focus mode Control Link functionality (outlined in white rectangle).

After entering Focus mapping mode, parameter and Control fields appear between the header and plug-in. This is where we do our hardware-control-to-parameter Control Link assignments. To complete a Control Link assignment, click on the arrow that points from a control to a parameter. This causes the arrow to flash yellow in Focus mode, or blue in Global mode.

Okay, let’s return to creating our control surface. To start with a clean slate, close MIDI-OX and Studio One if open, and turn off the Komplete Kontrol keyboard.

1. Turn on the Komplete Kontrol keyboard. After it “boots,” open MIDI-OX, and verify that it shows the correct MIDI devices (see Fig. 1 in Part 2). Leave MIDI-OX open, although it can be minimized.
2. Open the Komplete Kontrol stand-alone application. Click the application’s MIDI button in the upper-right corner, verify that you’ve chosen the desired template, and then click the MIDI button again to de-select the MIDI mode.
3. Open Studio One, and Create a new song. Press the Komplete keyboard’s MIDI button so that it’s lit brightly (if it isn’t already).
4. Click on Studio One’s Mix tab, and then on the External button toward the left. A column with External Devices appears.
5. Click the MIDI-OX arrow under External Devices. Choose Setup, and verify that it’s sending to and receiving from the correct Komplete Kontrol ports, as described in Part 2 (Receive From = Komplete Kontrol -1, Send To = Komplete Kontrol Ext-1). Click OK.
6. Now click on the MIDI-OX arrow again, and choose Edit. Click MIDI Learn, and prepare for an orgy of knob twiddling.
7. Turn your attention to the Komplete Kontrol keyboard, whose MIDI button should be brightly lit. Choose the control surface’s Page 1 with the left/right arrow buttons (if it isn’t already selected; check the keyboard’s right display, in the lower right, to confirm that it shows 1/4).
8. Turn all 8 keyboard knobs, below the display. Studio One’s External Devices window will sprout 8 controls. Widen the External Devices window so the 8 take up exactly one row, then choose page 2 with the keyboard’s right arrow button. Again, turn all 8 controls.
9. Similarly, choose page 3 and turn all 8 controls, then page 4. You’re now populating the External Devices window with all the available controls.
10. Similarly, do the same for the four pages of switches.
11. Fig. 2 shows our masterpiece of total control. The Komplete keyboard’s controls, switches, and pages are now recognized as a control surface for Studio One.

Figure 2: Studio One now recognizes the Komplete keyboard controls and switches as a control surface.

12. While in MIDI Learn mode, you can change the control graphic to (for example) a switch instead of a knob. To do so, click on the arrow in the CC label below the knob, and choose the desired graphic.
13. After setting up the control surface, turn off MIDI Learn (so you don’t brush up against a control and change something accidentally).
14. We’ll use Mojito as an example. Bring Mojito into an Instrument track, and strategize what control layout would be best for each page. Fig. 3 shows what I chose; in the labels, the first number is the page, the second the physical control or switch.

Figure 3. Komplete keyboard hardware assignments for Mojito.

15. Next, use Control Link to link the control surface knobs with the Mojito parameters. With Mojito in Focus mode as described above, move Control 1 on the keyboard or the external devices page, click on (or move) the Mojito Pitch control, and then click on the Arrow between them. The arrow turns yellow to confirm the link. Proceed similarly through all the controls and switches until they’re all assigned. (It’s a little complicated with the LFO Speed, because when you switch between the two LFO Sync options, you would actually need two knobs – one to vary frequency, the other to vary beats. I figured I’d use beats 99% of the time, so I used the hardware to control the LFO when in beats mode. For frequency, you can use your mouse to move the knob, or program a couple of the spare knobs that will be available on page 4.)
16. After programming your knobs, return to the Komplete Kontrol stand-alone app, click the MIDI button, and label the template’s knobs (Fig. 4). Now, when you choose the template, the knobs on the Komplete keyboard will show the parameters they affect. Done!

Figure 4: Labeling the template’s controls adds labels to the keyboard’s control surface.

After creating these templates, you won’t want to lose them—which you will if your hard drive crashes. Or maybe you’re going to do a re-install, or want your templates on a different computer. For more information, a helpful document on the NI web site tells where to find the Komplete Kontrol MK2 settings.dat file so you can copy it, or back it up.

NATIVE INSTRUMENTS/STUDIO ONE SYNERGY

If you have multiple templates and want to switch among them to control various instruments and effects while you work in a song, here’s the procedure.

1. Make sure the stand-alone Komplete Kontrol application is open (a Komplete Kontrol instrument can be open at the same time in Studio One, there will be no conflicts).
2. Enable the stand-alone Komplete Kontrol application’s MIDI button, choose the template, and then disable the MIDI button. (I usually minimize the Komplete Kontrol app after this, but it’s not necessary.)
3. Open the instrument or track you want to tweak, and press the keyboard’s MIDI button to enable communication. The keyboard’s MIDI button must be shining brightly to control instruments or effects in Studio One.

You can switch between controlling an instrument loaded in Komplete Kontrol, and a Studio One instrument that uses the currently selected template. This is pretty much automatic; when you select a track with Komplete Kontrol, the PLUG-IN button toward the keyboard’s upper right lights. When you select a non-NKS track, the MIDI button lights. However, you do need to change templates if you switch to an instrument or effect that doesn’t use the currently selected template.

Note that when you want to use the Komplete keyboard as a hardware controller, or to test your programming, the stand-alone app’s MIDI button must be turned off. Then you can press the keyboard’s MIDI button to communicate with the instrument or effect.

GETTING CREATIVE WITH YOUR TEMPLATES

If you’re tweaking one parameter at a time, arguably just grabbing the mouse, clicking on a parameter, and dragging is easier. But where hardware control really comes into its own is being able to adjust multiple parameters at the same time, like varying filter gain and frequency, envelope parameters, or compressor controls that interact, like threshold and ratio.

Also note that knobs can control drop-down menus. For example, in the Pro EQ, you can choose the LC and HC slopes, or the LF and HF filter types, with knobs. Another trick is redundancy. With my Pro EQ template, the filter parameters are spread over different pages. However, the 7 active/bypass switches for the filter stages are available on every page. That way, no matter which filter stage I’m adjusting, it’s possible to bypass or enable any other stage for diagnostic or comparative purposes.

Yes, it takes a bit of effort to program templates for everything you might want to control. While this may seem arduous at first, you need to create a template only once (although of course you can edit it if needed). After a while it becomes second-nature to switch over to the Komplete Kontrol stand-alone application, choose the desired template, minimize Komplete Kontrol, and carry on tweaking parameters. And, a particularly outstanding feature is that you don’t need to switch templates when controlling the same plug-in. A good use case is adjusting EQ during the mixing process. Call up your Pro EQ template, and it can apply to whichever EQ you select.

So now we can use the Komplete keyboard’s control surface not only to tweak NKS-format plug-ins, but virtually any plug-ins from any manufacturer—it even works with prehistoric wrapped DX and DXi plug-ins. Pretty cool!

Studio One 4.53 introduced integration with Native Instruments’ Komplete series of keyboards, which is a big deal. Although these keyboards are theoretically dedicated to NKS-compatible plug-ins and mixer/transport hands-on control, with Windows systems (Mac fans, there’s more on this later) you can use the keyboard as a general-purpose, hands-on MIDI controller for non-NKS plug-ins, including all bundled PreSonus effects and instruments (as well as plug-ins from other manufacturers). Also, unlike standard NKS, you’ll be able to control effects, regardless of whether or not they’re inserted in an instrument track.

There’s a lot to cover, and since this is more like a tutorial than a tip, it’s split into three parts: DAW control with Studio One, creating custom templates for plug-ins, and how to apply the templates in your workflow.

INTEGRATING THE KEYBOARD

Choose Studio One > Options > External Devices, and click Add. Scroll to the entry for Native Instruments, unfold it, and select either your A/M or S series keyboard for Receive From and Send To. I’m using an S49 (Fig. 1).

Figure 1: Komplete is selected as the keyboard, with Split Channel selected for more convenient use with multitimbral instruments, like IK Multimedia’s Syntronik.

INTEGRATING THE CONTROL SURFACE

Now let’s set up the Komplete keyboard as a new control surface. Again, choose Studio One > Options > External Devices, click Add, and scroll down to the entry for Native Instruments. Unfold it, and select Komplete Kontrol DAW – 1 for both Receive From and Send To (Fig. 2).

Figure 2: How to add the Komplete keyboard as a control surface for DAW integration.

CHOOSING THE MODE OF OPERATION

To edit NKS plug-ins, press the PLUG-IN mode button in the keyboard’s cluster of six buttons, toward the upper right. Controls that don’t relate to a synth or effect, such as the Transport, Metronome, Tape Tempo, and the like remain active. When it’s time to mix and you want full integration with Studio One’s mixer, press the MIXER button.

The following describes how the control surface for the current S-series Mk2 keyboards integrates currently with Studio One; click here for information from PreSonus on suitability with other NI keyboards, and updates.

Transport. The Play, Rec, and Stop buttons do what you’d expect, but there’s more to the story than that—there are several nuanced options. The following assumes you’re starting from a stopped transport.

• Press Play to begin from the Play Start marker. If there’s no Play Start marker, playback starts from the cursor’s current position. If you stop and re-initiate playback, playback re-starts from the cursor’s original position.
• Return to zero: When the transport is stopped, press Stop again to return to zero.
• Pushing on the big navigation knob toward the right initiates playback from the Play Start marker. (Note that this involves pushing downward into the knob, not left/right or up/down.) If there’s no Play Start marker, playback begins from the Loop Start, whether the loop is active or not.
• Push downward on the navigation knob during playback to jump to the Loop Start, which resumes playback automatically from there.
• Pressing Shift+Play operates the same way as using the navigation knob for playback control.
• With any scenarios involving the Play Start marker, it doesn’t matter if it’s before or after the Loop Start, or within the loop itself.
• Press Rec to initiate or punch-in recording. Press again to end or punch out recording. If you don’t record audio or MIDI while recording is active, there’s no blank event—it’s like nothing ever happened.
• Shift+Rec toggles the count-in between on and off. When you press Shift and count-in is enabled, the Rec button letters light bright red. Otherwise, the rec button letters are dimmed.
• Loop toggles the loop between on and off. To move the loop (whether enabled or not), hold the Loop button down, and rotate the navigation knob. For example, if the loop extends for four measures, moving the knob 1 click clockwise moves the loop forward to the next four measures. Moving the knob 1 click counter-clockwise moves the loop backward to the previous four measures.
• Metronome toggles between on and off.

Mixer

• The display for each visible channel shows the channel’s name, fader level, pan, metering (but not overloads), and status of a channel’s Record, Solo, and Mute buttons.
• Track select buttons. The eight buttons above the display select a track, however, moving the navigation dial left or right moves from one track to the adjacent track (left or right respectively).
• Hold Mute, and then select a channel with its track select button, to mute/unmute. The keyboard’s corresponding select button glows yellow.
• Hold Solo, and then select a channel with its track select button, to solo/unsolo. The keyboard’s corresponding select button glows blue.
• Shift+navigation knob move down (not push inward) selects level for the selected track. This mode remains selected until changed. Both the associated track knob, and the navigation knob, alter the selected track’s level. Holding Shift while moving either knob provides finer resolution. The individual track knobs provide the finest resolution.
• Shift+navigation knob move up (not push inward) selects pan for the selected track. This mode remains selected until changed. Similarly to level selection, both the track knob and navigation knob alter the selected track’s pan, and holding Shift while moving either knob provides finer resolution. The individual track knobs provide the finest resolution. Note: The Pan control for the Main channel is always shown panned full left. You can ignore this, because the Main channel doesn’t have a pan control anyway. The pan is centered properly.
• Auto toggles between Read and Touch (write) automation for the selected track. Be aware that you can’t choose automation off with Auto.
• Left/right arrow buttons select channels in groups of 8. However, if the last bank of eight has fewer than eight channels, the display will fill with the last eight channels. For example, if you expect the last bank to be channels 17-24 but only 22 channels are in use, the keyboard will display channels 15-22. This is by design, because it makes sure there aren’t any blank channels—you can always see eight channels at a time. If you hit the left arrow button, it won’t go back to channel 9, but be offset by the same amount as the previous bank. To “reset” the banks, hit the left arrow button until you’re back at the beginning.

Miscellaneous Functions

• Undo and Redo. For Redo, hold Shift and press Undo.
• Quantize. This quantizes whatever is selected, at the current quantize value.
• Tap this, even if not lit, for tap tempo. I love this feature when starting a song.

This takes care of the mixer and transport functions. Next week, we’ll cover how to create custom MIDI control setups using the Komplete Kontrol application, and that will prepare us for Part 3, which describes how to create “faux NKS” control surface capabilities for PreSonus instruments and effects. Yes, it really is possible…

In the comments for last week’s tip on varipseed-type formant changes, reader Randy Hayes asked if it was possible to change the tempo similarly so that you could play along with something at a slower tempo, then speed it back up (while still being the correct key). This was a common technique with tape, but because pitch and speed were locked together, there would be formant changes—whether you wanted them or not—when you returned the slowed-down track to pitch.

One of the MIDI’s great features is that you can sloooooooow down the tempo, play along with the slowed-down track, then speed it up to make it seem like you have lightning-fast technique. The good news is that with audio, you can slow down Studio One’s tempo without changing pitch, which sounds great in theory. The bad news is that this isn’t always a painless solution, because Events recorded at a slower tempo will likely need to be time-stretched when you return to the original tempo, and you may also need to call up the Inspector for Events or Tracks to specify how the Events should relate to tempo. Also, if there’s a Tempo Track with tempo changes, then you have to offset all the tempo data, as well as make sure you restore it to the proper tempo when you’re done.

Fortunately, there’s an easy way to record along with a song at a slowed-down tempo, and have the correct timing for the recorded part when you restore the song to its original tempo. This complements last week’s formant-changing trick; the technique starts off similarly but ends up quite differently.

1. Create a premix of your existing tracks with the Export Mixdown function. In the dialog box, check Import to Track and Close after Export (Fig. 1; outlined in white).

Figure 1: Use the Export Mixdown function to create a premix.

2. After the premix is imported, mute all other tracks except for the Imported premix track.
3. Select the premixed track, and right-click on it (Fig. 2), or open its Inspector (F4), to access the Speedup parameter. Note that this parameter can also slow down the speed, by entering a value less than 1.00.

Figure 2: Access the Speedup parameter by right-clicking on the premix.

4. Slow down the premix to the desired tempo with the Speedup parameter. For example, a Speedup reading of 0.80 means the song’s tempo is 80% as fast as it had been previously. Bear in mind that you can’t do a ridiculous amount of slowing down without affecting the audio quality of the track you’re recording, but overall, Studio One is quite forgiving.
5. Record the new track as you listen to the premix’s slowed-down tempo.
6. Before restoring the original tempo, the track you recorded has to start at the song’s beginning. If that’s where you started recording, fine. Otherwise, use the Paint tool to draw an Event between the start of the song and the start of your part, select them both, and type Ctrl+B to merge them together (Fig. 3).

Figure 3: The recorded guitar solo, with an added “dummy” Event that starts at the beginning of the song, prior to merging them together.

7. Now, right-click on the overdub you recorded so you can access its Speedup parameter.
8. Open up your calculator to determine how much you need to speed up the overdub. Divide 1 by the slowdown amount to obtain the correct Speedup amount. For example, if you slowed down to 0.80, then 1/0.80 = 1.25. So, set the recorded track’s Speedup parameter to 1.25 (Fig. 4).

Figure 4: Once the newly recorded track goes to the start of the song, change the Speedup parameter to compensate for the slowdown.

9. Delete the premix (or mute it if you plan to do more recording at the slower tempo), and unmute the other tracks. The part you recorded should now match the Song’s overall tempo, even if there are tempo changes.

Note that any vibrato will be sped up when you restore the new part to the original tempo. This may be something you want, but if not, just remember to apply a slower vibrato than usual. Also, the timing will be tighter—a note that’s off the beat by a bit will hit closer to the beat when sped up.

Sure, some people might think this is cheating. But back when recording studios started adding EQ or reverb to vocalists, that was considered cheating too. The technique is the skill with which we use our tools, and having “Studio One technique” can be just as important—and valid—as having technique on your chosen instrument.

Just remember, all that matters about music is the emotional impact on the listener. They don’t care what you did to produce that emotional impact!

Back in the days of tape, when dinosaurs ruled the earth and gas station attendants checked your oil, variable-speed tape recorders allowed changing the pitch of all the tracks with a single control. This was useful for many applications. The most common were speeding up masters a bit to make them a little brighter and tighter, doing tape flanging, and perhaps the most popular, changing vocal formants. If you transposed the recorder’s pitch down a little bit, recorded a vocal as you sang along with the lower pitch, and then transposed back up again on playback, the vocal formant would be higher and brighter. Similarly, for a darker, warmer sound, you could transpose up, sing along with that, and transpose back down again. The same principle worked with other instruments, but vocals were the most popular candidates for this technique.

The main limitation (although it could also be an advantage in some situations) is that the tempo and pitch were interdependent—a higher pitch meant a faster speed, and a lower pitch, a slower speed. This was useful for masters, because you could speed up and brighten a track by upping the speed by 2% or so. The Friday tip for June 8, 2018 covered how to emulate true, variable speed tape effects when working on a final stereo mix.

A major advantage of today’s digital audio technology is that pitch and tempo can be independent, and one of Studio One’s attributes is that the audio engine retains its sound quality with reasonable pitch changes (e.g., a few semitones). This makes it very easy to do the old tape trick of changing vocal formants; here’s how.

1. First, create a premix of your existing tracks with the Export Mixdown function. In the dialog box, check Import to Track and Close after Export (Fig. 1).

Figure 1: Use the Export Mixdown function to create a premix.

2. After the premix is imported, mute all other tracks except for the Imported premix track.
3. Select the premixed track, and right-click on it (Fig. 2), or open its Inspector (F4), to access the Transpose and Tune parameters.

Figure 2: You can access the Transpose and Tune parameters by right-clicking on the premix.

4. To brighten the vocal formant, use the Tune and/or Transpose function to lower the pitch.
5. Record the vocal track as you listen to the premix.
6. After recording the vocal track, right-click on the vocal Event, or open its Inspector, and tune it up by as much as you tuned the premix track down. For example, if you tuned the premix down a semitone, tune the vocal track up a semitone.
7. Delete the premix (or mute it if you plan to do more formant-shifted tracks), unmute the other tracks, and enjoy your formant-shifted vocal.

This is especially useful when doubling parts, because the double can have a slightly different timbre. And with background vocals, shift some formants up, and some formants down, for a bigger, more interesting sound. And of course, if you just can’t quite hit that high note…you’re covered. I promise I won’t tell.

I also like using this with guitar and other instruments. I’ve gotten away with pitching guitar up 7 semitones for a bright sound that splits the difference between a standard guitar sound, and one that’s more like “Nashville” tuning (as described in the Friday Tip for December 1, 2019). At the other end of the tonal spectrum, playing along with the premix tuned up, and pitching back down, is like using a low tuning on a guitar—great for those massive metal guitar sounds.

—————————————

As we enter 2020, thank you very much for your support of these blog posts, and your comments. Also, thank you for supporting the Studio One book series that I’m writing. When I wrote the first book, I wondered if there would be any demand for it, or whether I was just wasting my time. Well, you’ve answered that question… so now I’m working on book #5 of the series, about how to record great guitar sounds with Studio One. It won’t be done for a while, but it wouldn’t have been done at all without your support (or the great-sounding new amp sims, for that matter).

Finally, let’s all thank Ryan Roullard and Chad Schoonmaker, who wrangle the blog and social media each week to get this blog posted and promoted. It’s not like they don’t already have enough to do at PreSonus, which makes their involvement just that much more appreciated. Thanks guys!

FX Chains are a powerful Studio One feature, yet I can’t help but notice that when I write tips about FX Chains, some people are lost without a download…so I get the impression people might think that making FX chains is difficult. But it isn’t really, and your reward for creating one is a multi-effects processor that you can call up whenever you want, as well as assign controls that allow tweaking parameters without having to open up the effect GUIs themselves.

One of the most important aspects of mapping parameters to knobs is choosing the right Transition settings, so let’s delve deeper into how to make them do your bidding.

Transition Settings Explained

A great aspect of FX Chains is being able to map Macro knobs to multiple parameters and control them all simultaneously. For example, in the EZ Squeez tip for a one-knob compressor, a single Macro knob varied the Compressor Ratio, Release, Threshold, Knee, Attack, and Gain controls simultaneously. Because of this, when changes in the Ratio or Threshold parameter reduced the output, the Gain control could increase automatically to compensate.

When you map a parameter to a Macro knob, the default is for the knob to alter the parameter over its full range. But, you often don’t want to vary the parameter over its full range. For example, if you were creating a wah pedal effect with the Pro EQ, you wouldn’t want the filter to go from 20 Hz to 20 kHz. A more realistic range would be around 300 Hz to 2 kHz.

The Transition setting allows restricting the parameter range covered by a control. When you click on the small Transition graphic, a bigger view opens up where you can set the parameter’s upper and lower limits (Fig. 1).

Figure 1: Click on the small graphic window (outlined in orange) to open up a bigger view (outlined in red).

However, the calibrations are sometimes difficult to read, so it can be challenging to create a precise change. Fortunately, there’s an easy solution.

Suppose you want to change the Pro EQ LMF frequency from exactly 150 Hz to 2.4 kHz (five octave range) by turning one of the Macro knobs. To do this:

1. Open the Pro EQ GUI so you can see the LMF Freq knob, and “pin” the Pro EQ so that it remains visible.
2. Click on the Knob icon in the Pro EQ’s upper left. The Macro Controls panel will appear (or the Macro Control Mappings window if it was opened up last). Since we want to use the Macro Control Mappings window, if the Macro Controls panel appears, click on its little wrench icon toward the upper left.
3. Turn the knob at the bottom of the Macro Controls Mapping window fully counter-clockwise.
4. Open the larger transition window for the LMF – Frequency parameter.
5. Click on the transition line’s left node, and drag it while observing the LMF Freq knob in the Pro EQ. Stop dragging when it hits 150 Hz; you’ve now adjusted the knob’s lower limit. Note that it’s sometimes difficult to obtain a precise setting; you can’t, for example, type in direct value. You may want to temporarily slow down your mouse pointer speed (in the mouse section of your system properties) to make this easier.
6. Now we need to set the upper-frequency limit. Turn the knob at the bottom of the Macro Controls Mapping window fully clockwise.
7. Re-open the larger transition window for the LMF – Frequency parameter.
8. Click on the transition line’s right node, and drag it while observing the LMF Freq knob in the Pro EQ. This time, stop dragging when the knob’s frequency readout shows 2.4 kHz. Note that you won’t be able to reach exactly 2.4 kHz; the closest I could come was 2.38 kHz…close enough. It’s not always possible to hit a value exactly, but most of the time, this doesn’t matter.

This kind of precision came in handy when creating the Imaging Phaser, where I wanted each frequency band in the Pro EQ to cover five octaves, and the bands had to be offset an octave from each other.

Bend Me, Shape Me

The Transition setting has another very useful feature—you can click the node in the middle to bend the curve into different shapes. For example, the Gain parameter in the EZ Squeez compressor needed to increase in level as the settings became more extreme, which squashed the signal more and brought down the level. Dragging the midpoint down a bit accelerated the amount of Gain as the single knob was turned higher (Fig. 2).

Figure 2: Bending the Transition line alters the “feel” of controls.

Where the Heck Are FX Chains Stored, Anyway?

Whenever a FX Chain tip provides a download link, there’s an inevitable comment in the Comments section along the lines of “Where do I store this after I download it”? The easiest way to find out is to go to the Browser, expand the FX Chains folder, expand a sub-folder if necessary, right-click on an FX Chain, and choose Show in Explorer (Windows) or Show in Finder (Mac). Now you’ll know where your FX Chains live. Note that you can also specify the location for your presets in Studio One > Options > Locations > User Data.
