My patch is complete, except I wrote it all and tested it with my MIDI-keyboard. Testing it with the trumpet, it only reports new notes on note-off while playing legato. Playing staccato, that is initiating a new velocity with the breath controller for every note, this is not a problem. So, the first note in a row is always correct, but then it will start to be "delayed" – while playing keeping a continuous stream of breath.
I've tried seeing if I can readjust the musical instrument, but well, it isn't very friendly when it comes to interfacing. Could someone here who might have used a similar device, like an Akai EWI, direct me to some knowledge about how MIDI instruments works that keep me from making this work?
There isn't any problem when using the instrument with other software, like ABleton and other DAWs.
