how to not specify MIDI instrument?

[Tom Sgouros]

Hello all:

Is it possible to have Frescobaldi use whatever instrument is selected on my keyboard instead of asserting its choice of piano sounds?

I have a Lilypond file that does not specify a MIDI instrument, but Frescobaldi seems to insist on using the piano sound I like least on my keyboard. Is there a way to just have it send notes and not ProgramChange messages? Or some hack to get finer control of those messages?

Thank you,

 -Tom

I'm not sure this is a Frescobaldi issue as much as a LIlyPond issue.  See:

They tell me over on the Lilypond list that if I don't specify a MIDI instrument, that no Program Change event is generated. I can't seem to figure out how to take a MIDI file and export the events in it in a human-readable format, so I can't really confirm that, but I've played the file on another MIDI device and it didn't seem to care what instrument I set it on.

Thanks,

I have confirmed that there is no midi instrument specification (Program Change event) in the Midi file that Lilypond generates. Is there a way to keep Frescobaldi from asserting one?

Thanks,

I guess that’s because of the program change 0 sent when the output is reset https://github.com/frescobaldi/frescobaldi/blob/92ad12137135b1693f6041567c81d2fa0f4ecf28/frescobaldi_app/midifile/output.py#L53

Called by the MIDI player at https://github.com/frescobaldi/frescobaldi/blob/92ad12137135b1693f6041567c81d2fa0f4ecf28/frescobaldi_app/midifile/player.py#L331

Ah, I implemented that because it seems common. But I can change that,
or make it configurable. Added the issue as

Thanks!
