Friday Tip: Make Mastered Songs Better with Tempo Changes

We covered tempo changes previously, with an emphasis on using tempo changes to add dramatic pauses, and also doing longer changes that are useful with DJ sets when transitioning from one song to another. This week, let’s go one step further.


In the process of researching an article for about what made classic rock sound “classic,” I analyzed tempo variations in songs without click tracks. The consistency of these changes was surprising. Although the changes did not have machine-like precision, they were far from being random or sloppy. They tended to follow particular patterns not only in different songs, but different genres.


The most prominent of these was speeding up a bit in the verse before a chorus. Sometimes there would be a slight slowdown after arriving at the chorus, and sometimes it would revert pretty close to the original tempo over the course of the chorus, but the speeding up was evident in virtually all the music I analyzed—rock, pop, R&B, soul, you name it. Also, songs often sped up imperceptibly over the course of a song.


Although you can record while Studio One is doing a tempo change, sometimes it’s a lot easier to play along with a regular click. Fortunately, there’s a way to add these tempo changes after the fact, to the final stereo mix—consider it a mastering technique done in the Song Page, not a tracking or mixing one.




Working on the mixed track requires the highest fidelity possible. Choose Options > Advanced > Audio and check “Use cache for timestretched audio files.”


This uses a higher-quality timestretch algorithm than what’s used for real-time disk playback.


Next, open up a new song and load your mixed file into a track. It won’t have tempo information embedded so Studio One won’t know how to stretch it, but that doesn’t matter. Open the Inspector (F4), and enter a tempo under File Tempo, for example 120 BPM. It doesn’t have to match the original file’s tempo because we’re just introducing changes, not dealing with absolute tempos.


While you’re in the Inspector, choose Tempo = Timestretch, and Timestretch = Sound.




I generally do a linear speed up, because the changes (e.g., 2-5%) aren’t big enough that you’d notice a log curve anyway. While holding the Alt/Opt key, click with either the Paint or Line tool where you want the tempo to start speeding up, and drag to where you want the speedup to end. Note that you can also drag up or down to fine-tune the end tempo, and if you also hold Shift while doing this, you can change tempo in 0.1 BPM increments.


While the range of tempo changes is still selected, zoom in on the very first change. It will be slightly more than the tempo before it, which is usually what you want. If not, hover over the top of the first tempo change until it turns into a double up/down arrow. Click, and drag downward to even out the first tempo change with the tempo change right before it. The selected changes will follow along to preserve the line’s slope. Remember, we’re talking about small changes here that are more felt than heard as obvious tempo shifts. You can be off by a few tenths of a BPM, or even more—no one will notice.


The screen shot shows a mastered song after having tempo changes made. I like to extend the tempo track height as much as possible so it’s easy to make fairly precise changes. Note the linear changes that happen before the two choruses about 1/3 and 2/3 through the song, and then another before the final fadeout on the main riff. In the middle, there’s also a slightly slower tempo change during the solo.


Try this technique on your finished songs—you might be surprised about how these can help a song “breathe” and flow more, even if it was recorded to a click track.


Friday Tip: The TonalVerb

Okay, Studio One isn’t lacking for reverb. Nor is the rest of the world. But we also aren’t lacking for tools to make new kinds of reverb sounds, and that’s what this week’s tip is all about.

Note that the TonalVerb is a bus effect, so don’t insert it in a track. (Or, do insert it in a track—you never know what might happen!) As with last week’s tip there’s a preset you can download, but I recommend reading about how this preset works. FX Chains are very powerful, and once you learn what you can do with them, you can create your own signature sounds instead of sounding like everyone else.



A Splitter, set to Normal mode, feeds two Mixverbs in parallel. One of the parallel paths goes through a Mixtool with both channel phases (polarities) inverted, so the summed audio cancels. Except… one Mixverb has damping fixed at 50%, while the other is variable (as set by the FX Chain Tone control). With both Damp controls at 50%, there’s no audio due to cancellation. However setting damping below 50% cancels the low frequency reverb components, yet the high frequency reverb components remain. With damping set above 50%, the reverse occurs—the high frequency reverb components cancel, while the low frequency components remain. The closer Tone is to 50%, the greater the cancellation so you may need to increase the bus level under these conditions.

This effect is very different compared to altering tone via equalization for several reasons, but the main one is that damping varies over time. At the onset of the reverb, there’s more cancellation because the two parallel signals have more in common. This reduces the attack of the signal being reverberated, which has its own uses—for example, you might want the crack of a drum to be more prominent, rather than being washed in reverb. With tone set to 0% and Size at a relatively high value (e.g., 70%), it’s almost like the reverb has an attack time of its own.

Regarding the other FX Chain controls, Predelay, Size, and Width all vary their respective Mixverb controls simultaneously over their full ranges. The only one that works differently, as noted above, is the Tone (damping) control.

So… why be normal? Here’s your chance to try a different type of reverb sound that’s especially well suited to EDM productions.




Friday Tip: Old School-Style Tape Variable Speed

Back in the days of variable-speed analog tape, we often cheated and sped up the master just a bit. This had three beneficial effects: it made the tempo a bit more lively, raised the pitch for a slightly brighter sound, and tightened timing. Even a 2% change could make a significant difference. (If you ever tried to play along with an old pop tune and found your instrument had to be tuned somewhat sharp, this is probably why.)


Digital technology gave us a major advance by making it possible to change tempo without changing pitch, or change pitch without changing tempo. Curiously, though, there aren’t as many options if you want to change both simultaneously. Fortunately, Studio One can do this easily.


The key is the Inspector’s Speedup and Tune parameters. A speedup of 2% is about right for making a noticeable, but not obvious change; however many older masters were sped up a lot more than that, so don’t feel too constrained. For Tune, 20 cents works well as a general-purpose setting but again, there are no rules about this other than to use your ears.



If you enter these changes and then go back to 0 for the two settings, the song will sound less lively. However it’s important to acclimate yourself to any changes, either speeding up or “bypassed,”  before making any final decisions about what sounds best.


Note that I much prefer to do any master speed/tune change processing on the finished, two-track mix instead of while working on a song. That way I don’t need to remember to set the Speedup and Tune on each track, or render loops so I can use the needed parameters.


And since we’re in old school territory, consider adding a bit of Console Shaper as well from the Mix FX drop-down. I seldom push drive above 9 o’clock for program material, and some crosstalk makes the sound a bit more speaker-like when wearing headphones (with headphones, you don’t get acoustical crosstalk like you do with speakers, where the left ear hears some of the right speaker, and vice-versa). As to noise…well I’m not a fan of noise, but with some tracks, it does add a little “glue.” Or maybe it just triggers the psychological response of working with older gear.

The audio example plays an excerpt from the remix of “To Say No Would Be a Crime” (from my album “Simplicity”). The first 19 seconds are the original version, the rest of the example speeds it up by 1.02 with a pitch increase of 40 cents. The complete song is available on YouTube/thecraiganderton.


In any case, when you want your music to be a little more lively, brighter, and tighter, try raising the Speedup and Tune parameters just a bit. It really does make a difference.

Friday Tip of the Week: Patterns: Not Just for EDM

Some people see “Pattern” and think “step sequencing—not useful for anything other than EDM.” This tip shows how to use Patterns in a rock drum context to add humanized percussion easily and effectively.

First, let’s subject ourselves to a 16th-note pattern of shaker hits, which is the kind of sound that shows why people don’t like step sequencers. Someone who would use this in a musical context is either not a nice person, or perhaps a pharmaceutical company executive who wants to increase sales of headache remedies.


Let’s start improving matters by copying the shaker to two more pads, and creating some sonic variations.

One copy is transposed down two semitones, and has a shorter decay. The other is transposed down three semitones. All three have slightly different filter settings. By alternating the different sounds, we have something that’s better. Well, at least slightly better.

Let’s make it a lot better. We’ll make sure the original shaker sound hits at maximum velocity on every beat to establish a rhythm.

The second row uses a different shaker sound. Because this is a busier part, we’ll create some velocity variations.

Let’s also introduce some repeats so that two of the hits “stutter” a little bit.

However having repeats happen the same way every time doesn’t sound very realistic, and this is where the Pattern’s coolest feature (well, at least in my opinion) comes into play—Probability. The notes with repeats have a fairly low probability, so they’ll show up from time to time but not overstay their welcome. A few of the other notes have lower probability as well. Also, there’s some added swing—not only are Patterns not just for EDM, swing isn’t only for hip-hop.

Now we have a much more interesting shaker part.

If this is too inconsistent for you, it’s easy to make the velocity more similar, increase probabilities…whatever. And of course, we can create variations on these Patterns, make a few changes here and there, and have them sound similar yet different throughout the song.

Thankfully, Patterns don’t have to sound repetitive and boring…unless of course you want them to sound repetitive or boring. But that’s a whole other topic.

Friday Tip: The Customizable Phaser

Studio One’s Phaser is quite sophisticated, especially because you can set the number of stages from 2 to 20. This can emulate many classic phasers, as well as go beyond what was done with typical analog phase shifters. So why do we need yet another phase shifter?

As explained last week, a phaser’s response is like an EQ with multiple notches, because a pair of phase shift stages produces one notch. So for example, if you set Studio One’s Phaser to 8 stages, it produces four notches. The Customizable Phaser differs from standard phasers because every filter stage can be either a notch or peak, to any degree you want. Mixing resonant peaks in with notches produces a sound that recalls a phase shifter, but has a uniquely resonant quality.


Again like last week, the Pro EQ is the star of the show. The five parametric stages are spaced an octave apart and cover a four-octave range. The trick is having a single Frequency control alter all five stages simultaneously… here’s how.


Creating the FX Chain

Although there’s a downloadable preset, delving into how this effect works is instructive. Mapping a control panel knob to a stage’s gain control is easy; open up the control panel to access the Macro Controls Mapping, and for the five Gain knobs, chose the respective Gain parameter as a target. I limited the knob’s range to -24 dB and +18 dB, because a +24 dB peak can be too much gain. After adjusting one knob as desired, copy the graph and paste it into the graph for the other knobs. Map Q similarly; a range of 4 to 16 works well.


Mapping and offsetting multiple parameters from a single knob is a little more difficult. Start by pinning both the Pro EQ and the Macro Controls Mapping windows. I chose the initial frequencies for the five stages as 75, 150, 300, 600, and 1200 Hz. For the Knob 1 macro, add each stage’s Frequency control as a target.

Suppose you want to map the LF-Frequency target. Set the Frequency knob full counter-clockwise, click on the target’s graph, and while looking at the LF Freq knob on the Pro EQ, adjust the graph’s low node so that the LF Freq knob is at 75 Hz (or thereabouts). Now turn the Freq control fully clockwise, and set the graph’s high node four octaves higher (1.2 kHz) according to the LF Freq knob.

Proceed to the next filter Freq knob and use the same general procedure. For example for the LMF stage, the initial frequency would be 150 Hz, and the highest frequency would be 2.4 kHz. Continue mapping the remaining stages until all the filters cover the desired range when you move the Frequency control.

You’ll also note the Low Cut control is mapped to a knob that covers the range of 20 Hz to 1 kHz. Use this if the signal becomes too “boomy” with the frequency control set to a lower range.


In use

With all the Gain controls set to minimum and a fairly sharp Q, you have the equivalent of a 10-stage phaser. Now try increasing the LMF and HMF gains to around 8 or 9 dB—you’ll hear an immediate difference in the sound. Vary the Q for even more variations. You’ll find that between the Q and Gain controls, it’s possible to obtain phase-shifter sounds, but more importantly, you’ll be able to dial in combinations of resonant peaks and notches that aren’t quite like anything you’ve heard before. Ready for a new phase in phaser sounds? Check out this FX Chain.



Friday Tip: The Imaging Phaser

I’ve been experimenting with phasers lately, and found some interesting tricks. This week we’ll create a mind-melting phaser-meets-stereo-imager. Next week, we’ll create a super-customizable phaser with continuously variable peaks and notches, so you can obtain specialized vintage sounds like the original Electro-Harmonix Polyphase.


You can reproduce the sound of a phaser with several tracking notch filters, so instead of using a phase shifter per se, we can use the Pro EQ.

The five parametric stages are set up as notch filters one octave apart, with a sweep range of four octaves. The FX Chain Frequency control sets their frequencies. If you download the multipreset, I highly recommend reverse-engineering it to see how to control multiple filter stages from a single knob.

The FX Chain Q control sets the phase effect’s resonance/sharpness by altering the Q for all five stages simultaneously. Broader Q settings reduce volume, with a less focused, gentler phasing sound. High Q settings are sharper, with a more pronounced phasing effect.

But the secret ingredient here is splitting the signal path into the Pro EQ-meets-phaser and the Mixtool. Inverting the phase for the Mixtool’s left and right channels cancels out any remaining dry signal from the Pro EQ “phaser,” which accents the phasing sound.


If you compare this to the sound of the PreSonus Phaser, it’s like the PreSonus Phaser supplements the audio with the phasing effect, while the Imaging Phaser replaces the audio with the phasing. They both have their uses.



The real mind melt happens if you run program material through the Imaging Phaser and then click the Image Xpand button. This swaps the right and left channels, which because they’re out of phase, creates insane imaging effects. The first time I tried this was on a laptop, and clicking on Image Xpand made it seem like the speakers were located somewhere else in the room. The effect is less dramatic with signals that don’t contain a lot of stereo information and ambiance, or on headphones, but it still makes a difference.



The first part showcases the phaser effect. After the word “Reunited” appears, you’ll hear an unprocessed version of the track for four measures. After that, it’s Image Xpand time, with the FX Chain control being varied to alter the sound somewhat.


And for those without the patience to build their own Imaging Phaser, here’s an FX Chain multipreset you can download. Have fun!

Friday Tip: The Project Page Meets Bluetooth

The Project Page Meets Bluetooth
After mastering a project, I like to check out its suitability in a variety of contexts by listening to it over and over again—in the foreground, in the background while people are talking, while the dishwasher runs, whatever. This can be very instructive when trying for masters that are transportable not just for different playback systems, but for different listening conditions.

And that’s when it hit me: Bluetooth! I have IK Multimedia’s iLoud portable Bluetooth speaker, and carry it around the house to listen to music that’s streaming from a mobile device. Why not carry it around while listening to a mastered Project? Or even loop a Song, so I can get lyric ideas while the instrument tracks play in the background? Or listen over other Bluetooth devices, to get an idea of the type of sonic violence the music will have to endure at the hand of consumers?

Okay, so I was a little slow to tumble to this…but reality checks can indeed be useful, and I hope you find this tip useful as well. We’ll do the Mac first, and then Windows.

1. Choose Apple menu > System Preferences > Bluetooth.
2. Turn on Bluetooth at the Mac if it isn’t already.
3. Turn on your Bluetooth playback device, and enable pairing for it (usually by pressing a pairing button on the device).
4. When the Connection Request appears, click Connect.

5. The Bluetooth window will show the device as connected.
6. In Studio One, choose Preferences.

7. For Playback Device, choose your Bluetooth playback device.

1. Choose Settings > Devices > Bluetooth & other devices.
2. Turn on Bluetooth in Windows if it isn’t already.
3. Click on Add Bluetooth or other device, then choose Bluetooth when Add a Device appears.
4. Turn on your Bluetooth playback device, and enable pairing for it (usually by pressing a pairing button on the device).

5. Click on the device name to connect it. Once it’s connected, click on Done.
6. In the Windows search box, type Sound and then select Sound Control Panel.

7. Your Bluetooth device should appear in the list of potential playback devices. Click on it, and then click Set Default to make the Bluetooth device your default playback device.
8. Now that Windows is set up, open Studio One, and choose Options. Select Windows Audio for your Audio Device, and you’re good to go.

Friday Tip: Pedal Power

Here’s a follow-up to last Friday’s tip on creating an authentic sounding wah with the Pro EQ. That’s fine, but what if you want to control it with a footpedal instead of a mouse? Keep reading.

First, you need a pedal that generates MIDI data. There are several options. Most keyboard controllers have an expression pedal input. Plug an expression pedal into this, and the controller will likely output controller 11 over MIDI. You may be able to assign this to a different controller number (see your hardware’s documentation); however, this probably won’t be necessary.

If you don’t have a keyboard (or floor multi-effects with a pedal that produces MIDI out), then check out the Pedal Controller, a small box from MIDI Solutions. This accepts an expression pedal input and outputs your choice of MIDI controllers. (For do-it-yourselfers, the circuit board is small enough you can probably mount it in a pedal if you want a stand-alone MIDI pedal.)

Assuming you’re using a keyboard with an expression pedal input, you now need to add the control surface to Studio One if you haven’t already. Call up the Options menu, and add the keyboard. Here, I’ve added The Laboratory controller from Arturia.

Next, you need to map the pedal. Go to the right-hand side of the Control Link menu and select the device to open the Device Control map. Note that The Laboratory is selected as the device. 

If you can’t see the right section of the Control Link menu, then your monitor resolution is probably 1600 pixels wide or less. Another way to open the Device Control map is to open the Mix view [F3], and then click on External in the Console navigation column (to the far left of the Console). This opens the External panel; double-click on the desired device in the External panel.

Now click on the Device Control’s MIDI Learn button, and then move the footpedal. As if by magic, Control 1 appears, with its controller number assignment.

Now whenever you want something in Studio One to react to the footpedal, you just select Control 1. You can also rename this—perhaps not surprisingly, I changed Control 1 to Footpedal.

Now let’s suppose you want to control the Pro EQ Mid Frequency (Freq) control, which we used last week to vary the wah frequency. It’s simple:

  1. Vary the Freq control.
  2. Move the pedal.
  3. Right-click on the Freq knob.

Now choose the desired assignment—in my case, “Assign MF-Frequency to Footpedal on the Laboratory.” Move the pedal, and it will change the frequency.

However, you probably don’t want the pedal to cover the full frequency range, but just a typical wah’s range so you have more precise control. We have a solution for that, too. Instead of right-clicking on the knob and assigning it to the footpedal, assign it to a Channel Macro Control, like Knob 1. Open up the Channel Editor, right-click on Knob 1, move the knob, next move the pedal, and then choose “Assign MF-Frequency to Footpedal on the Laboratory.” (By the way, you can assign pretty much everything in Studio One to a controller using the right-click + move controller + choose assignment protocol.)

Now you can use the Transition settings graph to limit the pedal’s range. Alter the curve shape to a response you like—it doesn’t have to be linear—or even change the “sense” of the pedal travel so that pulling back on the pedal raises the wah frequency.

Once you’ve done this kind of assignment a few times, it will become second nature and you’ll be able to take advantage of pedal power for increased expressiveness. So put your foot down, get on the good foot, or put your best foot forward—the choice of clichés is yours!

Friday Tip: The Studio One Wah Pedal

You never know where the next gig is coming from—maybe it’s joining a disco revival tribute band, being asked to play guitar on a remake of Shaft, or getting a quick $200 from a YouTube producer to come up with a background theme for their “Remembering the ’70s” docu-series.  What do all of these have in common? Yes! The magic of the wah pedal.

A mint condition Vox Crybaby pedal can sell for up to a grand, but no worries—this Friday’s tip reveals the “secret sauce” for getting a can’t-tell-the-difference-from-the-real-thing wah pedal sound.


Now you might say “C’mon Craig, try to come up with something better next week, okay? It’s no big deal. You just put a ProEQ parametric stage in your guitar track, set it to a relatively high Q, and vary the frequency.” But actually, it’s not that easy. A real wah doesn’t just have a peak that pokes its head up in the middle of the frequency spectrum, but has steep high and low frequency rolloffs on either side of the peak—and we can do that with parallel processing.

  1. Set up a Splitter in Normal split mode.
  2.  Insert the ProEQ in one split, and the Mixtool in the other split.
  3. Invert both the Left and Right channels in the Mixtool. If you play guitar through this, you should hear nothing because the out-of-phase MixTool is canceling out the audio.
  4. Create a parametric peak. You’ll want a fairly high Q and gain, depending on which wah you’re modeling.

Now sweep the frequency back and forth, and you’ll swear you’ve been transported back in time to when wah pedals ruled the earth. This is due to the cancellation on either side of the peak from the Mixtool being out of phase.

And by the way… wahs can also sound great in parallel with bass, and in parallel with drums when you want to add a dose of funk. So don’t spend a grand on a vintage wah—just make your own with Studio One.

Friday Tip: Using DX and DXi Plug-Ins with Studio One

Using DX and DXi Plug-Ins with Studio One

The DX and DXi (instrument) plug-in formats for Windows were developed in the late 18th century, shortly after the invention of the steam-powered computer. Okay, okay…they’re not really that old, but development of new DX plug-ins ceased years ago when VST became the dominant plug-in lifeform for Windows. Regardless, you may still have some DX plug-ins installed on your computer from other programs, and want to use them.

Like many other programs, in theory Studio One doesn’t support DX/DXi plug-ins. However, it does support shell plug-ins (e.g., like Waves uses). This means you can use a wrapper that makes DX plug-ins look like they’re VST types. With this workaround, Studio One can “see” and load DX and DXi plug-ins because it thinks they’re VSTs.

I’ve tested the following with many DX and DXi plug-ins, from several manufacturers, in 64-bit Studio One. They can’t do sidechaining, and 32-bit plug-ins that were never updated to 64 bits aren’t compatible with 64-bit Windows, but otherwise they work as expected. Here’s how to make your DX and DXi plug-ins productive members of Studio One society.

  1. Go to
  2. Download the zip file
  3. Extract it.
  4. Copy the files dxshell.x64.dll and dxishell.64x.dll to the folder where Studio One looks for VST plug-ins.

That’s pretty much all there is to it. Open Studio One, and you’ll see all the DX and DXi plug-ins—the screenshot shows plug-ins from Cakewalk, rgc:audio, and Sony. The Instruments tabs will show any available DXi plug-ins.

I don’t have a 32-bit system so I didn’t test this with 32-bit DX shells. But if it works like the 64-bit one, you should be covered there as well.

Granted, this is a bit of a hollow victory because if a DX plug-in’s functionality is available with Studio One’s VST plug-ins, you’re better off using the VST versions. But there are still some DX effects that have no real equivalents in the modern world—and now you can use them.
