|Summary||0007381: malformed MIDI track|
|Description||when i was recording a MIDI track with ardour 5.9, it was displayed totally messed up and stayed that way. the GUI also became noticeably slow at scrolling when the MIDI track was visible.|
this only happened with one of three MIDI tracks in that project, so the MIDI interface was actually working fine. we recorded MIDI before without problems.
|Steps To Reproduce||record MIDI.|
|Additional Information||so far it only happened once. the problem was not present in the same project when recording another midi track.|
|Tags||No tags attached.|
Those are sysex MIDI messages, and lots of them it seems.
Ardour records all incoming MIDI (incl Sysex) and in the GUI visualizes them as a vertical line at every sysex message start and print the raw data in a lane.
Did you perhaps record some keyboard state-dump or some control-surface messages?
