| Summary | 0007511: crash loading prior session with MIDI | ||||
| Description | I can record MIDI notes, which show in the region. I can import MIDI files which show in a region. But on playback I have no activity on the MIDI meter, and no activity in the MIDI monitor. If I hook up my keyboard to a-fluidsynth or CalfFluidsynth, the plugin plays sounds which can be heard and appear on the MIDI monitor and MIDI channel meter (edit view). I've verified that all notes are on channel 1, there is a playable sound for that channel and the same notes showing in the region verify that the patch selected will sound for that range. If I record MIDI from the keyboard, it too shows up in the region but won't play. Finally, after some length of time, Ardour may crash by itself. Regardless, if Ardour is restarted and you try to open this session, it crashes with the following: ardour-5.10.375: /usr/include/boost/smart_ptr/shared_ptr.hpp:648: typename boost::detail::sp_member_access<T>::type boost::shared_ptr<T>::operator->() const [with T = ARDOUR::MidiTrack; typename boost::detail::sp_member_access<T>::type = ARDOUR::MidiTrack*]: Assertion `px != 0' failed.
