Hi, did anybody attempt to program a polyphonic midi delay, possibly with delay time and feedback control via CC ?

Hi and welcome to the Bome community!

You might search the forum on “chord”. That might get you started. For instance, to recognize a chord, you would have to interpret the arrival of several notes (polyphonic), to determine the incoming chord and of course, since it would take time to interpret the chord, a delay would be necessary.

Worth separating two problems here: repeating notes, and doing it polyphonically without stuck notes.

The repeat part is the easy half — a translator on Note On that outputs the same note with a Delay, then re-triggers itself with a decreasing velocity, gives you feedback taps. The velocity scaling is your feedback amount, and you stop re-triggering once velocity drops below a threshold, otherwise it runs forever.

The polyphony part is where people usually come unstuck. Each voice needs its own timer/delay identity, so use the note number as part of the timer name rather than one global timer — otherwise a new note cancels the tail of the previous one. Same for Note Off: send a matching Note Off after each delayed tap, or you’ll get hanging notes as soon as you play chords.

For CC control, keep delay time in a global variable and read it when scheduling rather than baking a fixed number into the delay, so turning the knob affects the next taps instead of nothing.

One caution from experience: at short delay times with a lot of feedback you can generate a lot of MIDI very quickly. Cap the number of taps explicitly rather than relying on the velocity floor alone.
