A VCA Channel has a fader, but it doesn’t pass audio. Instead, the fader acts like a gain control for other channels, or groups of channels. In some ways, you can think of a VCA Channel as “remote control” for other channels. If you assign a VCA to control a channel, you can adjust the channel gain, without having to move the associated channel’s fader. The VCA Channel fader does it for you.

Inserting a VCA channel works the same way as inserting any other kind of channel or bus. (However, there’s a convenient shortcut for grouping, as described later.) To place a channel’s gain under VCA control, choose the VCA Channel from the drop-down menu just below a channel’s fader…and let’s get started with the applications.

APPLICATION #1: EASY AUTOMATION TRIM

Sometimes when mixing, you’ll create detailed level automation where all the moves and changes are perfect. But as the mix develops, you may find you want to increase or decrease the overall level. There are several ways to do this, like inserting a Mixtool and adjusting the level independently of the automation, or using the automation’s Trim control. However, a VCA control is sometimes easier, and besides, it can control several channels at once if desired, without having to feed them to a bus. The VCA fader can even offset automation for multiple tracks that are located within a Folder Track (Fig. 1)

• Figure 1: Note how the label below each fader says VCA 1. This means each channel’s gain is being controlled by the VCA 1 fader on the right. If all these tracks have their own automation, VCA 1 can bring the overall level up or down, without altering the automation shape, and without needing to send all their outputs to the same bus.

If the automation changes are exactly as desired, but the overall level needs to increase or decrease, offset the gain by adjusting the VCA Channel’s fader. This can be simpler and faster than trying to raise or lower an entire automation curve using the automation Trim control. Furthermore, after making the appropriate adjustments, you can hide the VCA Channel to reduce mixer clutter, and show it only if future adjustments are necessary.

APPLICATION #2: NESTED GROUPING

One of the most common grouping applications involves drums—when you group a drum kit’s individual drums, once you get the right balance, you can bring their collective levels up or down without upsetting the balance. Studio One offers multiple ways to group channels. The traditional option is to feed all the outputs you want to group to a bus, and vary the level with the bus fader. For quick changes, a more modern option is to select the channels you want to group, so that moving one fader moves all the faders.

But VCAs take this further, because VCA groups can be nested. This means groups can be subsets of other groups.

A classic example of why this is useful involves orchestral scoring. The first violins could be assigned to VCA group 1^st Violins, the second violins to VCA group 2^nd Violins, violas to VCA group Violas, and cellos and double basses to VCA group Cellos+Basses.

You could assign the 1^st Violins and 2^nd Violins VCA groups to a Violins Group, and then assign the Violins group, Violas group, and Cellos+Basses group to a Strings group. Now you can vary the level of the first violins, the second violins, both violin sections (with the Violins Group), the violas, the cellos and double basses, and/or the entire string section (Fig. 2). This kind of nested grouping is also useful with choirs, percussion ensembles, drum machines with multiple outputs, background singers, multitracked drum libraries, and more.

Figure 2: The 1^st Violins and 2^nd Violins have their own group, which are in turn controlled by the Violins group. Furthermore, the Violins, Violas, and Cellos+Basses groups are all controlled by the Strings group.

Although it may seem traditional grouping with buses would offer the same functionality, note that all the channel outputs would need to go through the same audio bus. Because VCA faders don’t pass audio, any audio output assignments for the channels controlled by the VCA remain independent. You’re “busing” gain, not audio outputs—that’s significant.

If you create a group, then all the faders within that group remain independent. Although with Studio One you can temporarily exclude a fader from a group to adjust it, that’s not necessary with VCA grouping—you can move a fader independently that’s controlled by a VCA, and it will still be linked to the other members of a VCA group when you move the VCA fader.

Bottom line: The easiest way to work with large numbers of groups is with VCA faders.

APPLICATION #3: GROUPS AND SEND EFFECTS

A classic reason for using a VCA fader involves send effects. Suppose several channels (e.g., individual drums) go to a submix bus fader, and the channels also have post-fader Send controls going to an effect, such as reverb. With a conventional submix bus, as you pull down the bus fader, the faders for the individual tracks haven’t changed—so the post-fader send from those tracks is still sending a signal to the reverb bus. Even with the bus fader down all the way, you’ll still hear the reverb.

A VCA Channel solves this because it controls the gain of the individual channels. Less gain means less signal going into the channel’s Send control, regardless of the channel fader’s position. So with the VCA fader all the way down, there’s no signal going to the reverb (Fig. 3)

• Figure 3: The VCA Channel controls the amount of post-fader Send going to a reverb, because the VCA fader affects the gain regardless of fader position. If the drum channels went to a conventional bus, reducing the bus volume would have no effect on the post-fader Sends.

APPLICATION #4: BUS VS. VCA

There’s a fine point of using VCAs to control channel faders. Suppose individual drums feed a bus with a compressor or saturation effect. As you change the channel gain, the input to the compression or saturation changes, which alters the effect. If this is a problem, then you’re better off sending the channels to a standard bus. But this can also be an advantage, because pushing the levels could create a more intense sound by increasing the amount of compression or saturation. The VCA fader would determine the group’s “character,” while the bus control acts like a master volume control for the overall group level.

And because a VCA fader can control bus levels, some drums could go to an audio bus with a compressor, and some drums to a bus without compression. Then you could use the VCA fader to control the levels of both buses. This allows for tricks like raising the level of the drums and compressing the high-hats, cymbals, and toms more, while leaving the kick and snare uncompressed…or increasing saturation on the kick and snare, while leaving other drum sounds untouched.

Granted, VCA Channels may not be essential to all workflows. But if you know what they can do, a VCA Channel may be able to solve a problem that would otherwise require a complex workaround with any other option.

This Friday tip has multiple applications—consider the following scenarios.

You like to mix with mastering processors in the Main bus to approximate the eventual mastered sound, but ultimately, you want to add (or update) an unprocessed file for serious mastering in the Project page. However, reality checks are tough. When you disable the master bus processors so you can hear the unprocessed sound you’ll be exporting, the level will usually change. So then you have to re-balance the levels, but you might not get them quite to where they were. And unfortunately, one of the biggest enemies of consistent mixing and mastering is varying monitoring levels. (Shameless plug alert: my book How to Create Compelling Mixes in Studio One, which is also available in Spanish, tells how to obtain consistent levels when mixing.)

Or, suppose you want to use the Tricomp or a similar “maximizing” program in the master bus. Although these can make a mix “pop,” there may be an unfair advantage if they make the music louder—after all, our brains tend to think that “louder is better.” The only way to get a realistic idea of how much difference the processor really makes is if you balance the processed and unprocessed levels so they’re the same.

Or, maybe you use the cool Sonarworks program to flatten your headphone or speaker’s response, so you can do more translatable mixes. But Sonarworks should be enabled only when monitoring; you don’t want to export a file with a correction curve applied. Bypassing the Sonarworks plug-in when updating the Project page, or exporting a master file, is essential. But in the heat of the creative moment, you might forget to do that, and then need to re-export.

THE “DOUBLE-DECKER,” PRE-MAIN BUS SOLUTION

The Pre-Main bus essentially doubles up the Main bus, to create an alternate destination for all your channels. The Pre-Main bus, whose output feeds the Main bus, serves as a “sandbox” for the Main bus. You can insert whatever processors you want into the Pre-Main bus for monitoring, without affecting what’s ultimately exported from the Main bus.

Here’s how it works.

1. Create a bus, and call it the Pre-Main bus.
2. In the Pre-Main bus’s output field just above the pan slider, assign the bus output to the Main bus. If you don’t see the output field, raise the channel’s height until the output field appears.
3. Insert the Level Meter plug-in in the Main bus. We’ll use this for LUFS level comparisons (check out the blog post Easy Level Matching, or the section on LUFS in my mixing book, as to why this matters).

Figure 1: The Pre-Main bus, outlined in white, has the Tricomp and Sonarworks plug-ins inserted. Note that all the channels have their outputs assigned to the Pre-Main bus.

4. Insert the mastering processors in the Pre-Main bus that you want to use while monitoring. Fig. 1 shows the Pre-Main bus with the Tricomp and Sonarworks plug-ins inserted.
5. Select all your channels. An easy way to do this is to click on the first channel in the Channel List, then shift+click on the last channel in the list. Or, click on the channel to the immediate left of the Main channel, and then shift+click on the first mixer channel.

With all channels selected, changing the output field for one channel changes the output field for all channels. Assign the outputs to the Main bus, play some music, and look at the Level Meter to check the LUFS reading.

Now assign the channel outputs to the Pre-Main bus. Again, observe the Level Meter in the Master bus. Adjust the Pre-Main bus’s level for the best level match when switching the output fields between the Main and Pre-Main bus. By matching the levels, you can be sure you’re listening to a fair comparison of the processed audio (the Pre-Main bus) and the unprocessed audio that will be exported from the Main bus.

The only caution is that when all your channels are selected, if you change a channel’s fader, the faders for all the channels will change. Sometimes, this is a good thing—if you experience “fader level creep” while mixing, instead of lowering the master fader, you can lower the channel levels. But you also need to be careful not to reflexively adjust a channel’s level, and end up adjusting all of them by mistake. Remember to click on the channel whose fader you want to adjust, before doing any editing.

Doubling up the Main bus can be really convenient when mixing—check it out when you want to audition processors in the master bus, but also, be able to do a quick reality check with the unprocessed sound to find out the difference any processors really make to the overall output.

I’m still wrapping my head around PreSonus giving us amp sims that are light years beyond the original Ampire in a free update…and also making them available for use in other programs. But now that they’re here, let’s take advantage of them before PreSonus’s accounting department changes its mind.

The new amp sims do not supplement the old Ampire, but replace it. New Studio One owners will have only the new amps; existing users will find that the legacy presets were removed. If you need to get the older presets back because you used them in pre-4.6 projects, simply install the Ampire XT Classics extension—but I’d recommend redoing any presets with the new amps, because they sound so much better. (The Ampire XT Metal Pack works with the new Ampire, but you may need to re-install it.) The PreSonus Knowledge Base has an article with everything you need to know about making the conversion from the old Ampire to the shiny new Ampire XT.

Why Bi-Amp?

Bi-amping a guitar amp is useful for the same reason that most studio monitors are bi-amped—just as you can optimize the speakers for high and low frequencies, you can optimize the amps for high and low frequencies. For example, with heavily-distorted chords, the high strings will be equally distorted and relatively indistinct. With bi-amping, the lower notes can have a big, beefy distortion sound, while the high notes ring out on top—which is the subject of this Friday tip.

Let’s take a bi-amped preset apart to find out how it works. This preset is available on the PreSonus Exchange, so if you just want a cool, crunchy rhythm sound, go ahead and download it. But the real value here is learning how to make your own presets, because this preset was made using my guitar, pickups, strings, playing style, pick, and follows my musical tastes. It’s unlikely you play guitar in exactly the same way, so it’s worth tailoring any amp sim preset—not just this one—to your own playing style and gear.

Recording the Guitar

Guitars are mono, but to play stereo games, we need to convert a mono track to dual mono. This allows using processors like the Binaural Pan.

1. Record a mono guitar track with Channel Mode set to Mono.
2. Change Channel Mode to Stereo.
3. Select what you recorded.
4. Choose Bounce Selection (ctrl+B). Now your guitar part is dual mono (e.g., the same part in both the left and right channels), so Studio One recognizes it as stereo.

The FX Chain Multipreset

Fig. 1 shows the FX Chain “block diagram.” The Splitter is doing a Frequency split; frequencies below 924.7 Hz go to the left split, while frequencies above that go to the right split.

Figure 1: Bi-amp Multipreset block diagram.

Next up is choosing the amps,  and setting their parameters (Fig. 2). The left split uses the MCM 800, a revered British amp that can marshall its resources to give big, beefy sounds. The right split’s VC30 amp is known amongst the vox populi for its bright, ringing high end, so the two amps are ideal for delivering the desired result.

Figure 2: Left split (on top), right split (below).

Now let’s enhance the amp sound with some EQ, reverb, and stereo imaging to spread out the reverb a bit more (Fig. 3).

Figure 3: Final touches for the bi-amp multipreset.

The EQ adds the equivalent of an amp’s “bright” switch. With a non-bi-amped preset, you have to be very careful about adding brightness because it can emphasize any artifacts caused by intermodulation distortion. But that’s not an issue here, because of the VC30’s a clean high end. The gentle low-frequency roll off simulates more of an open-back cabinet sound. The reverb is sort of a cross between a spring and room sound, while the Binaural Pan spreads out the reverb signal for a wider stereo image. The pan setting is fairly conservative; feel free to widen things further.

This multipreset makes an excellent template for further adventures with bi-amplification. Of course, this just scratches the surface of what’s possible with these new amps—so stay tuned to the Friday Tip of the Week for more applications.

This FX Chain complements the Tightener FX Chain presented in the October 25, 2019 Friday Tip. Whereas the Tightener reduces the presence of the key center in a piece of audio, the Resonator enhances the key center by adding resonance. The download at the end includes twelve Resonators—one for each key.

The heart of each Resonator FX Chain is two delay lines whose period correlates to a particular key, and are tuned an octave apart from each other. Mixing the delayed, resonant sound with the dry sound imparts a sense of pitch, which can be useful with unpitched instruments (such as percussion) to blend in better with melodic instruments. It can also help create a sense of pitch for drums that aren’t tuned properly, as well as emphasize any instrument’s key center.

For example, suppose it’s hard to get a shaker part to fit in a mix because its level is either too high and stands out, or is too low and sinks into the track. Adding a feeling of pitch may allow mixing the part a bit higher, while also having it blend into a mix more seamlessly. If taken to an extreme (and the FX Chain allows for that!), the Resonator has special effects potential for sounds like “cylon” voices, or tuning reverb.

The Controls

Figure 1: Each Resonator has six controls; the Resonance control is the most important one.

The controls (Fig. 1) are pretty straightforward, and cover the full travel of the Analog Delay controls. There’s no need to tweak any Transform curves.

• [key name] Resonance varies the mix of the resonant and dry sounds. Most of the time, mixing in even a bit of resonance may be all you need.
• Sharpness adds feedback to create more intense resonance.
• Width determines whether the resonance is stereo or mono. Most of the time, you’ll probably want to leave this control fully clockwise.
• Saturation, Low Cut, and High Cut controls are “because we can” controls. You may not use them much, but hey, an FX Chain allows for eight controls…so why not?

Striking the Right Chord

You can also use the Resonators to impart the sense of a chord by sending a sound to FX Channels, loaded with appropriate Resonators. Fig. 2 shows a shaker part acquiring a more melodic vibe via resonators for the keys of D, F#, and A. This produces a D major chord tonality.

Figure 2: Sending the audio from a shaker to three FX Channels “tunes” the shaker to a D major chord.

Although I came up with this mostly to process unpitched sounds, I’ve found it has other uses as well. For example, with an acoustic guitar part, a Resonator can add a vibe that’s not unlike the drone strings on a sitar. The best implementation I’ve found for this is putting the Resonator in an FX Channel, and automating a send so that the resonance is added only in certain strategic parts. And of course, if you want to get crazee, you can always turn up the resonance and sharpness, and do cylon voices. Fun stuff!

Okay, this is an unusual one. Please fasten your seat belts, and set your tray tables to the upright and locked positions.

Personal bias alert: With pop and rock music, for me it’s all about vocals, drums, and bass. Vocals tell the story, drums handle the rhythm, and bass holds down the low end. For a given collection of songs (formerly known as an “album”), I want all three elements to be relatively consistent from one song to the next—and that’s what this week’s tip is all about. Then the other instruments can weave in and out within the mix.

It’s fantastic that you can flip back and forth between the Project page and a Song that’s been added to the Project page, make tweaks to the Song, then migrate the updated Song back to the Project page. But it’s even better when you can make the most important changes earlier in the process, before you start down the final road of mastering.

Here’s a way to match bass and vocal levels in a collection of songs. This takes advantage of the Project page, but isn’t part of the mastering process itself. Instead, you’ll deploy this technique when the mix is in good shape—it has all the needed processing, automation, etc.—but you want a reality check before you begin mastering.

We’ll cover how to match vocal levels for the songs; bass works similarly, and in some ways, more effectively. Don’t worry, I’m not advocating robo-mixing. A mathematically correct level is not the same thing as an artistically correct level. So, you may still need to change levels later in the process—but this technique lets the voice and bass start from a “level” playing field. If you then need to go back and tweak a mix, you can keep the voice and bass where they are, and work the mix around them.

(Note that it’s important to know what the LUFS and LRA metering in the Project page represent. Rather than make this tip longer, for a complete explanation of LUFS and LRA, please check out this article I wrote for inSync magazine.)

1. Create a test folder, and copy all your album’s Songs into it. Because this tip is about a diagnostic technique, you don’t want to overwrite your work-in-progress songs.
2. Create a new test Project.
3. Open a copied Song, remove any master bus processing, and Choose Add to Project for the test project. Add all the other songs on the album to the test project. Do not normalize the songs within the test project.
4. Open the Loudness Information section for each song, and select the Post FX tab. Adjust each song’s individual level fader (not the master fader) so all songs have the same LUFS reading, then save the Project. The absolute LUFS value doesn’t matter; choose a target, like -20 LUFS. (When adjusting levels, 1 dB of level change alters the LUFS reading by 1. For example, if a song registers at -18.4 dB, decrease the level by 1.6 dB to reach -20 LUFS. Check and re-check by clicking on Update Loudness as needed until the LUFS readings are the same.)
5. Choose a Song to edit (click on the wrench next to the song title). When the Song opens, solo only the vocal track. Then choose Song > Update Mastering File. Note: If a dialog box says the mastering file is already up to date, just change a fader on one of the non-soloed tracks, and try again. After updating, choose View > Projects to return to the test project.
6. Repeat step 5 for each of the remaining Songs.
7. Select all the tracks in the Project page, then click on Update Loudness.
8. Check the Loudness Information for each song, which now consists of only the vocal (Fig. 1). For example, suppose the readings for six songs are (1) -24.7, (2) -23.8, (3) -24.5, (4) -22.7, (5) -23.1, and (6) -24.3. Those are all pretty close; we’ll consider -24.5 an average reading. The vocals on songs (1), (3), and (6) have consistent levels. (2) and (5) are a tad high, but song (4) is quite a bit higher. This doesn’t mean there’s a problem, but when you go back to using the original (not the copied) Songs and Project, try lowering the vocal on that song by 1 or 2 dB, and decide whether it fits in better with the other songs.

Figure 1: The songs in an album have had only their vocal tracks bounced over to the Project page, so they can be analyzed by the Project page’s analytics.

The waveforms won’t provide any kind of visual confirmation, because you adjusted the levels to make sure the songs themselves had a consistent LUFS reading. For example, if you had to attenuate one of the songs by quite a bit, visually the vocal might seem louder but remember, it’s being attenuated because it was part of a song that was louder.

Also try this technique with bass. Bass will naturally vary from song to song, but again, you may see a lager-than-expected difference, and it may be worth finding out why. In my most recent album, all the bass parts were played with keyboard bass and generated pretty much the same level, so it was easy to use this technique to match the bass levels in all the songs. Drums are a little dicier because they vary more anyway, but if the drum parts are generally similar from song to song, give it a try.

…But There’s More to the Story than LUFS

LRA is another important reading, because it indicates dynamic range—and this is where it gets really educational. After analyzing vocals on an album, I noticed that some of them had a wider dynamic range than others, which influences how loudness is perceived. So, you need to take both LUFS and LRA readings into account when looking for consistency.

For my projects, I collect all the songs I’ve worked on during a year, and release the completed project toward the end of the year. So it’s not too surprising that something mixed in February is going to sound different compared to something mixed in November, and doing something as simple as going back to song and taking a little compression off a vocal (or adding some in) is sometimes all that’s needed for a more consistent sound.

But let me emphasize this isn’t about looking for rules, but looking for clues. Your ears will be the final arbiter, because the context for a part within a song matters. If a level sounds right, it is right. It doesn’t matter what numbers say, because numbers can’t make subjective judgments.

However, don’t minimize the value of this technique, either. The reason I stumbled on it was because one particular song in my next album never seemed quite “right,” and I couldn’t figure out why. After checking it with this technique, the vocal was low compared to the other songs, so the overall mix was lower as well. Even though I could use dynamics processing to make the song reach the same LUFS reading as the other songs, this affected the dynamics within the song itself. After going back into the song, raising the vocal level, and re-focusing the mix around it, everything fell into place.

A couple previous tips dealt with how to give mono instruments, like guitar, a stereo image that won’t degrade when collapsed to mono. Widen Your Mono Guitar—Sans Problems used delay, but in a way that minimized phase issues. Delay-Free Stereo from Mono used two Multiband Dynamics, set for no compression, to separate the audio into bands that you could then pan left or right.

This tip takes the process even further—it’s versatile, relatively simple, easily customizable, and also, has no phase issues when collapsed to mono. I’ve even used it to create a subtle, artificial stereo image from old mono records.

The Stereo Separator is particularly effective with power chords and rhythm guitar, especially as an alternative to layering parts in search of a “bigger” sound—you can obtain a stereo spread with a single track, so the sound is more defined compared to using multiple layers. And of course, if you scroll to the end there’s a downloadable FX Chain, so you can start playing with this immediately.

This example assumes a mono, distorted guitar track, like what you’d obtain by using a single mic on an amp. To create a stereo image, we first need need to convert this to a stereo track. So, set the track’s Channel Mode to stereo, and bounce the track to itself (Ctrl+B) to convert it into a dual mono (i.e., stereo, but with the same audio in the left and right channels). Now we can start playing with the stereo imaging.

1. Open the track’s Channel Editor, and select the Routing Window. Drag a Splitter into the Channel Editor. Choose 5 splits, and Frequency Split for the Split Mode. The defaults split frequencies are fine, at least for now.

2. Add a Dual Pan processor to the four high-frequency splits. You usually want the bass frequencies centered, so we’ll forego a split in the lowest-frequency split. You now have a Channel Editor that looks like Fig. 1.

Figure 1: The Channel Editor, with Frequency Split selected, and the Dual Pan effects inserted.

3. Fig. 2 shows the macro control assignments. It’s pretty straightforward—the four pairs of knobs are for the Low (L), Low Mid (LM), High Mid (HM), and High (H) frequencies. Each section has left and right Pan controls, which are assigned to the Pan knobs. The left Pan knob is also assigned to the linked Width control, and the right Pan knob ties to the linked Pan control as well. Each section’s buttons are assigned to Link and Bypass.

Figure 2: The Macro control assignments.

4. When Linked, the Left Pan knob becomes the Linked Width control, and the Right Pan knob becomes the Linked Pan control. The labels for the controls (Fig. 3) show the default control first, while the = sign shows the function when Link is enabled.

Figure 3: The Macro control panel. All the knobs and buttons are used.

And now, the fun begins! Play with the Pan controls to spread the different frequency bands in the stereo field—the audio example gives a good idea of the type of effect this FX Chain can do. The first example is mono, the second widens the image a bit, and the final example does a somewhat more radical stereo image.

Of course, you can go into the routing window, and change the levels of the various splits. Or, add FX in the splits…change the split frequencies…there’s enough to keep you busy for a while. Happy stereo!

This technique dates back to when I was doing live gigs with Brian Hardgroove from Public Enemy—me on guitar, him on drums. Since there was no bass player, we needed a way to fill out the bottom end. I’ve come up with a bunch of ways to do that over the years, but the technique presented here is the easiest one yet to implement. We’ll extract a bass line from an existing guitar track, without using MIDI or virtual instruments—here’s how.

Start by copying the guitar’s audio to a new track, which will become our faux bass track. Call up the Inspector, and transpose the faux bass track down by -12 semitones (Fig. 1). This technique works best with relatively articulated guitar notes, not rhythm guitar chords.

Figure 1: Start by transposing the Faux Bass track down an octave.

Now, it may seem like transposing down an octave is enough, and we can all go home now. No! The faux bass track needs three processors to sound right (Fig. 2).

• Pro EQ. This takes off the high end. If you transpose the high frequencies down by ‑12 semitones, you end up with midrange frequencies, and that’s not what we want. We want to transpose the low frequencies, to make them lower.
• Saturation Knob. If you’ve ever played bass, and pushed the sound through a vintage 1964 Ampeg B-15 bass amp, then you know why we need a bit of saturation. The object is to give the bass some “growl,” not only so it stands out a bit compared to the guitar, but also so it has a somewhat aggressive edge.
• People tend to limit or compress bass…who am I to argue? Again, this helps differentiate the faux bass track from the guitar and provides a more solid low end.

But as they always say, the proof is in the pudding. However, since we’re not providing a recipe about how to make pudding, check out the audio example instead.

The first two measures are the guitar by itself, while the second two measures have the faux bass playing along. Pretty cool, eh? Oh…and if you’re in a Cream tribute band, this will definitely come in handy for “Sunshine of Your Love.” Have a great weekend!
