| Summary | 0010276: Ardour crashes when creating a midi track below an audio track and then recording audio | ||||
| Description | When recording audio on an audio track above a midi track that has been expanded, the application crashes when the audio recording goes past the midi clip region and is stopped. GDB backtrace is attached. | ||||
| Steps To Reproduce | 1. Create new project 2. Create audio track 3. Create midi track with default instrument (reasonable synth). 4. Create a midi clip 5. Add notes to the clip from bottom sheet 6. Expand the midi editor in the timeline and edit some notes. 7. Record audio that goes past the midi clip. 8. Ardour crashes as soon as recording is stopped.
