@Enkerli Going deeper in the Kilgore link there is his hardware version in Arduino. Great way to get the function off the PC screen and into a single function box.

@Stringbender Right. But #RasPi is my “Golden Hammer” and it can work headless. There are great #Arduino projects but #SonicPi makes more sense to me.
My plan is to run a script like this from a headless Raspberry Pi with the #pisound HAT. Might use sensors later on.

@Enkerli The options for manifesting the same rotating harmonies principles on such different types of system, are inspiring. I believe it would work on Hollyhock too, using built-in modules and maybe some glue logic patches to fill the gaps. Next time I remind myself how Hollyhock works it will be tempting to make a rack for that. Putting a midi guitar through it could be interesting.
