Summary0003989: External MIDI keyboard crashes ardour
DescriptionHi!

When switching (recalling) a preset on my external Korg microX, ardour crashes with the following message:


ardour-3.0: ../libs/evoral/evoral/midi_util.h:92: int Evoral::midi_event_size(const uint8_t*): Assertion `(buffer[end] & 0x80) == 0' failed.
Aborted

Version is Ardour3.0alpha4 (built using ['9362'] and GCC version 4.5.2)

jack_midi_dump looks like this:

[more f8 events before]
0: f8

[now switching the preset]

0: c0 11
0: 0 0 f7
0: f8
0: f8
0: f8
0: f8
[more f8 events afterwards]

I've also attached the raw MIDI capture done with amidi, JFTR.


Cheers

adi: is this still an issue with alpha5?

Just checked with the alpha5 tarball from the ardour website: Yep, it's exactly the same behaviour.

after more testing and discussion on IRC, we've established that the problem here is that neither a2jmidid nor the -X seq backend correctly handles the way that the ALSA sequencer breaks apart sysex messages longer than 256 kB. so the fix for this is in those two blocks of code, rather than Ardour.
