So I’m trying to reverse engineer the “relaxation drone” factory preset.
They’ve got the gate open and keyboard off, with a really slow sample and hold set to stair step that triggers the gates, resulting in the chord being played repeatedly. But here’s the thing: the gates trigger for each oscillator, one at a time, like slowly strumming a chord. What is doing that?
I figured out the speed of the strum is controlled by the speed of the LFO that is being stair stepped by the s&h, yes. But I don’t know how to produce that lag between the oscs on my own from scratch. Any thoughts?
Probably it’s sample and hold modulating waveshape - this allows you to go to 0% pulse width at on the S+H steps that are above a certain voltage - which makes the VCO silent for that step.
One of my favorite tricks. By setting the VCOs to different amounts of pulse width (This is between ~2:00 and full CW on the wave pots) you can get some to cut out while others are still sounding.
