piezo (audio) to midi device?

does anyone know a cheap module like a doepfer (they don’t have
anything like it) that accepts audio input from a mic or piezo and
generates midi velocity e.g. note on/off commands. I need it for a
piece where i use some piezos to trigger from drums and cymbals. I
don’t want to use any edrum module, as they’re to expensive and mighty
for the task and i also use some of the audio from the piezos as well
anyway. Until now i’ve done the triggering in max itself from the audio
signal, but i could use the cpu and interface bandwidth for other
things than drum triggering.
All i’d need is a possibility to set note number and triggering
sensitivity (threshold).
Thanks for any help

You could get a second hand Alesis dm5 they have 12 trigger inputs and work quite well for this kind of thing.

I made a quick one using a multi-channel audio in box and MSP…linked thresholds to midi events. You could probably get several cheap USB audio devices and use them at the same time if you are on a Mac.

Though basically you’re re-implementing the MIDI drum box…

i think the cheapest solution is roland pm16 trigger to midi unit.
there are many other similar devices, but this one is quite common
and very cheap.

other solution is alesis D4. itshouldn’t cost more than 100$.

did you tried bonk~ ?
not so cpu intensive, very low latency, and with a good template, you
could use only one audio input and 1 bonk~ instance for all your
