| Steps To Reproduce | Open new project. Add MIDI track (General MIDI Synth). Select CUE page. Double click empty CUE slot on MIDI Track (General MIDI Synth) Select Keyboard Shortcut 'D' to draw Draw notes. Playback . Works. Edit notes. Maybe it works. Playback. Maybe works. Keep fidgeting with playback and editing until a crash happens. This happened on three out of three projects. These were new projects with only 1 MIDI track with General MIDI synth as the instrument. | ||||
| Additional Information | Other MIDI Instruments plugins are also affected. | ||||
| Tags | No tags attached. | ||||

Homebuild with GCC UBUNTU 24.04 LTS. Git pulled Dec 6th (b915435). Crashed on previous commits with homebuilds as well. Ardour.org Nightly build was not tested. |
