Yep. That's the one.. but it does like 5ths or 3rds or some shit as it decays out. It sounds dope. Kind of like the random number generator.
You bring up an interesting point ... I'd like to try maybe injecting the loop before the 741 stage and see how that changes things. My platform of inspiration was the way Tom did the Ab-synth.. It's totally a simple feedback loop and it sounds amazing. I may need to put maybe a 500k pot in series with a 200k or something just so it's never a straight loop.
It may be worth investigating it at as a momentary stomp with an "always on" toggle .. so you can turn it on with the toggle and dial in the noise you want, or just depress the momentary for bursts of glitching.
Please share what you come up with and try Ben, I'm very curious.
I'll update with what I find as well... currently I'm planning on using the tone bypass on a stomp.. but I don't usually actually use it that way, so maybe change that to a toggle and put the momentary glitch on a stomp.. I don't want 3 stomps on the device.
