I’ve been working on an STM32 granular processor on and off for about a year now. It’s called Sands, and if you follow my instagram you’ve probably seen some of its development.

I’ve managed to get the hardware working (based around an STM32f446 with a WM8731 audio codec), but I’ve hit a bit of a brick wall with it sonically. Everything is working as expected, but I’m not as excited by the sound as I am with my Glitch Delay, which I use on pretty much everything!

I had an idea to port the firmware to VCV Rack, so I could easily try it with lots of different modules (with one or 2 exceptions, I only really own modules I’ve built myself). Here is a very simple example (ironically I do own Rings and a Turing Machine).

If anyone interested in granular wants to try Sands on VCV Rack (Mac only currently), then email me. I’m keen to get feedback, and suggestions, or even see it working in a patch you’ve made.
