I create new file. Change instrument at bar 5 with bar settings. No problem.

But with import midi file I have a problem. I open a midi file with one melody line. It is put on the melody track in BIAB and the melody track is renamed to Piano by BIAB.

But now the midi patch change to a guitar (and any other instrument) is ignored and the pianist keeps playing. If I mute the piano I have silence. So the mute works.

Any suggestions?
