Happy you enjoyed it
The akai is a midi controller, that controls the 4 delay lines. The patch is quite simple : They are 7 or 8 oscillators and a simple next - previous system to select the oscillator. It now has a screen to show me what oscillator is selected. It then goes into a VCF and then fed into one of 4 delay lines. They each have a feedback control and some speed control combinations.
The patch is now in the community library. I'm sorry not to have any time to clean in up, but I have special folder called "messymix" and in this you can find a big number of my (messy) patches.
So the patch in this video would be : axoloti-contrib/patches/mtyas/messymix/Ribbon/with menu/ (multiosc or multios2)
