I'm trying to use pure data as MIDI filter before to entry to my DAW (Reaper) because I would like to modify the behaviour of a percussion midi device. The device send the message note on and off at the same time but I would like to use the percussion pad like a trigger. So with first stroke note is on and stay, second stroke note is off.
I'm able to do it entirely on pure data to control an oscillator or a sampler, but I'm not able to replicate this behaviour when I send midi message to the DAW trough noteout object. In fact I can send note on and stay to reaper but any note off.
Can someone explain me the right way to do that?
