Yop,
here a midifier workbench to play with settings in order to find the best set for a given source.
It's based on a [sigmund~] pitch and note onset, with an input [qompander~] object.
The starting point is getting noise ground level, and then deciding how much db's you add to it to send an noteoff message (intended for live mic input, but a test file structure is provided). This calibrating operation is done letting the microphone connected without playing or singing anything for 1s after clicking the bang button.
The patch outputs a midi stream that can be connected to any synth, but a simple visualisation is provided. Midi stream is monophonic thanks to lifesaver [poly 1 1] object.
I read [sigmund~] help, but I weren't very happy with the sensitivity of some arguments. A midi gate can be switched on, to avoid note onset messages beeing taken into accound if below a ceiling dB value.
Further midi filtering should be implemented in order to limit "re-triggering". (not even sure it works).
