Using #SonicPi Free Software, was able to emulate the “Michael Brecker Effect” pioneered by Robby Kilgore: http://robbykilgore.com/?p=19

Here’s my code:

@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.
@Stringbender To me, creating it in a few lines of Sonic Pi opens neat possibilities. It's like one of those learning projects. Simple enough to be encouraging, flexible enough to allow for further integration, and fun enough to be engaging.
