You can fine-tune families of instruments by boosting their volume with this handy technique.
Welcome to another Dojo! This month, I’d like to show you the benefits of creating and using VCAs (Voltage Controlled Amplifiers) when mixing, for added control and nuance. Tighten up your belts. The Dojo is now open.
Diving right in, what is a VCA? Think of it as a glorified volume-only control that uses voltage to adjust the amount of a signal’s/track’s volume when routed to its output.
Say you want to easily adjust the overall volume of your drum tracks within your mix. Perhaps you have several drum-loop tracks, drum machine soft synths with MIDI sequence tracks, and a full drum kit with multiple mics spread over multiple tracks (you know, a typical session). Or you might want to combine (sum) four individual rhythm-guitar track outputs into one VCA and be able to control the overall volume of all four from one channel. You can create a single VCA channel for all the drum tracks, another VCA for the rhythm-guitar parts, and then assign the outputs of those grouped tracks to their dedicated VCAs. Now, you can globally tweak the overall volume of all your drum tracks and all your rhythm guitars in your mix without changing the routing, plug-in levels, or effects sends, or the panning of any other tracks or groups.
The benefits of using VCAs really emerge after a mix has come together. For example, you might need to make an “all guitars up” version of the mix, or a “drums down 2 dB” version, etc. You may even want to automate volume rides in certain sections of a song—particular licks and fills, or even solos. You can also do this with vocals, background vocals, synths, etc.
Following the hypothetical example above, I’m going to show you how to create a VCA within Pro Tools and assign it to tracks of your choosing. Remember, every DAW has its own idiosyncratic way of creating and setting up a VCA channel, so be sure to consult your help section and/or read your instruction manual. Key commands may differ, but the process is essentially the same.
Fig. 1
Fig. 2
First, group (Cmd+G) all the tracks you want to be assigned to a VCA and name that group. I’ve named my group “DRUMS” [Fig.1]. Now, I’m going to create a VCA. Cmd+Shift+N, select VCA, and name it. I’ve named this “DRUMS” as well [Fig.2].
Fig. 3
Notice the new VCA channel and how there are no options for FX inserts, EQ, or panning [Fig. 3]? That’s exactly what we want, and it’s proof that we’ve set it up correctly.
Fig. 4
Finally, I’m going to assign my drums into a single VCA by clicking on the “no group” button and selecting “DRUMS” from the dropdown list [Fig.4]. That’s it!
Now you can rinse and repeat as many times as you like for as many instrument groups as you like. This is where VCAs really shine and can help you fine-tune specific volume relationships of instruments (and groups therein) within the fluid environment of a mix.
If you’re new to using VCAs, allow me to offer some suggestions that will help you get the most out of employing them. I use VCAs after I’ve shed proverbial blood, sweat, and tears obsessing over all aspects of the mix. Only after I feel like I’ve worked out a solid approach to EQ, compression, effects, parallel processing, outboard gear, aux busses, and all automation do I start using VCAs. On a self-judged scale of 0 to 10, my mix should be hitting about a 9. Then, I’ll typically fold all drum tracks into a single VCA, all bass (synth, stringed, etc.), all electric guitars (minus the solos), all synths and keys, all background vocals, and then group the lead vocal(s) and instrument solo(s) if appropriate. In this case, I have six VCAs to control the entire mix from a high level, and I can automate gain (volume) rides as needed to get that extra bit of focus and excitement out of the mix.
Next month, I’ll be guiding you through how to use aux busses to make your mixes better at an earlier stage.
Blessings and keep rockin’! Namaste.

StewMac International House of Overdrive Pedal Kit, With Bare Enclosure
The IHOO is based on the Crowther Hot Cake, an overdrive that became available around 1976. It was one of the earliest hand-made boutique effects pedals available. The circuit was designed to be what is now referred to as a “transparent” overdrive. An effect that enhances the player's sound while keeping the original tone intact.
This circuit has undergone many changes since its inception, and we have further expanded on the design by returning to an earlier version most revered by players and removing the buffer, which resulted in a reworked circuit that is true bypass but still retains the charm of the design.
We also include the original LM741 IC chip found in the originals, as well as the TL071 that is found in later versions so you can experiment with which IC best suits your playing style.
On this Wong Notes, the legendary Doobie Brother, Steely Dan member, and session weapon talks the science of music and how to defuse conflict—whether on the world stage or in the sound booth.
“Skunk” Baxter has had an interesting career. The Washington, D.C.-born musician was one of Steely Dan’s founding members in the early 1970s, and played on some of their most iconic numbers, like Can’t Buy a Thrill’s’ “Reelin’ in the Years” and “Do It Again,” or Pretzel Logic’s “Rikki Don’t Lose That Number.” Then, he moved on to join the Doobie Brothers, from roughly 1974 to 1979, where he fatefully invited Michael McDonald into the band. After that stint, he became a go-to session player for artists like Rod Stewart, Joni Mitchell, Dolly Parton, and Donna Summer, and a touring performer for Elton John and Linda Ronstadt, among others.
That was just the beginning. Baxter’s interest and background in electronics, science, and recording technology gained him a position in the U.S. defense industry. Turns out, a lot of digital music gear shared similar principles with emergent defense tech. “Basically, a radar is just an electric guitar on steroids,” says Baxter, noting the same four fundamental forces at work over everything in our universe.
Wong and Baxter trades notes on how to navigate studio sessions (“Just shut the hell up,” offers Baxter), early conversions of pitch into digital signals, and how Baxter cut his solo on Donna Summer’s “Hot Stuff” on a $25 guitar. And can mediating between artists and producers feel like high-stakes hostage negotiations? Sometimes. Tune in.
