SOOTY It runs on Bela mini without any more limitations on the full size Bela. Notice the Bela mini has the same CPU, so processing power is the same.
Bela mini also has enough inputs/outputs to run the vocoder. Let me know if you need pointers to hook it up. The code should work without modification as long as you get the hardware connections done properly.
Let me know if you have troubles and I'm happy to help. I have a Bela mini, so I can work out the kinks if there are any.
