I know that there are a lot of topics concerning MIDI output, and I spent the last hours reading them.
In one of the posts I also found the nice patch from tonfilm (attached). Now I’m wondering how to send a simple NOTE ON to test the connection. Is it just by selecting a NoteNumber and a Velocity > 0?
if “auto send” is on, just change the velocity value. if not, you have to bang “do send”.
… and dont forget to send a velocity 0 or note off command after starting a note, to release the note.
