I have an Increment3 module's increment pin triggered by a note-on via MIDI, so that every time the specific note is played it switches to the next patch in a Soundfont bank - it's a make-shift round robin type of thing.
The problem is it only works when the interface is visible (on screen).
When the interface is closed the increment pin isn't triggered at all.
If anyone has an explanation as to why this could be I'd be really grateful for all comments.
Thanks.
