Have you ever wanted to record and edit automation for your modular? Well, you can do this with a control surface like the Mackie Control. The concept is really simple, so we constructed a wordless demo. We used eight ramps from Volta to control what you hear:

LFO speed (driving the clock of an analog sequencer)
filter cutoff
filter resonance
VCA envelope attack
filter envelope attack
oscillator PWM
Z5000 CV in
VCA amount controlling Z5000 reverb return into mix

We set up a camera to record the video pass where we're recording the automation from the Mackie Control, then, without moving the camera, recorded another video pass of the DAW playing the automation back, and dissolve so you can watch the faders move without my hands.

We found that this system was useful even without the automation recording aspect, for example, if you've ever wanted convenient, simultaneous, precision, real-time access to multiple parameters on your modular. Moving long faders is far easier than twisting tiny knobs shrouded in patch cables.
