Set List, sending Prog.Change error

I need to sending Prog.Change when switching a song in set list.
When apply extra midi message, error no midi block defined at…

Maybe that helps

No, please explain

You have to ‘name’ a MIDI-OUT block (to be done with ‘set handle’) so you can ‘address’ it correctly when you want to use it, as explained here:

In Pianopauls example the MIDI-OUT was named ‘mySynth’ - so the command line has to start with the name of the MIDI-Out where the messages should be sent to.
(of course the synth that is to receive the message has to be physically connected to this port)

Ahh, now I got it!
Thanks a lot

FYI I realized there’s a use case to be able to address arbitrary MIDI output devices so the next update allows you to specify a midi device directly and not just blocks

Great, thanks!
