[Denemo-devel] [bug #40911] MIDI instrument list is not correct

[anonymous]

Follow-up Comment #1, bug #40911 (project denemo):

I have looked into this, and found that the problem seems to be that the sf2
presets are stored in arbitrary order, not sequentially. Each preset header
carries the preset name, preset number(this is what you want to sort by) and
bank number.

I've tried to come up with a patch for this but it's a bit over my head, and
my C skills seem to have become rusty. I extended the ParseSoundfont function
to also return the bank number, and currently sort only those presets that are
on bank 0, by looking at the preset number and using g_list_insert() instead
of g_list_append(), and throw away everything else. For some reason I fail to
understand currently, the sorting still doesn't work as it should, I hope
someone can investigate. I'm not sure about the code in set_properties (struct
callbackdata *cbdata), which also calls ParseSoundfont(), I haven't seen it
running in gdb during my tests but I may have missed something.

I append a git diff with my changes against current master.
