| Summary | 0010417: Pianoroll: automation late doesn't respect selected channel, crashes Ardour | ||||
| Description | When multiple MIDI channels are used within the same region, Ardour does not always display the correct automation data in the pianoroll automation lane. After switching to a different MIDI channel, it becomes impossible to draw new automation events for the newly selected channel. If the automation lane is then closed and reopened, Ardour crashes. | ||||
| Steps To Reproduce | 1. Create a new session. 2. Create a MIDI track and draw a region. 3. Open the pianoroll and draw a note (for example, on channel 1). 4. Open a pianoroll automation lane for a controller (e.g. Modulation) and draw some automation data on the same channel. The automation is displayed correctly. 5. While still in the pianoroll, select another MIDI channel (for example, channel 2) and draw a note. Everything should still work correctly at this point: the note is displayed properly, and the automation lane for channel 2 is empty. 6. Try to draw automation on the existing automation lane. This is no longer possible – the automation disappears immediately. 7. Close the automation lane and reopen it, selecting the same controller as before (e.g. Modulation). 8. Ardour crashes. | ||||
