Summary	0010424: Ardour9.7.56 crashing on selecting an empty midi slot in cue grid that is supposed to open piano roll.
Description	Ardour9.7.56 crashing on selecting an empty midi slot in cue grid and printing the following report: Set cursor set to default locate to 0 took 123 usecs for 1 tracks = 123 per track ardour-9.7.56: ../libs/midi++2/midi++/midnam_patch.h:394: const std::string& MIDI::Name::CustomDeviceMode::channel_name_set_name_by_channel(uint8_t): Assertion `channel <= 15' failed. Aborted ardour9 This happens most of the time on first start. If the crash doesn't happen on first attempt to open a piano roll of the cue, the following attempts after that don't cause the program to crash. This crash happens to me about 90% of the time. The few times it does work (doesn't crash) I can not find out why.
Steps To Reproduce	1. Open Ardour9 and open a new session. 2. Click "Window" -> "Cue Grid" -> "Show Cues" OR press "alt + c". 3. Right click in the middle of the screen, in "Template/Type" choose "Midi Tracks" and click "Add and close" (keep the default ACE Reasonable Synth" as it's not relevant afaik). 4. On the left side of the screen click (either left or right click) any empty box under the newly created synth instrument. The program will instantly exit and print the error provided in the description above (in case ardour was ran from the terminal ofc. otherwise crash will have no indication of error).
Additional Information	The system the crash happened on in case its relevant: Void Linux x86_64 with dwm (X11) window manager. The audio driver is Pipewire. Hardware: 12th Gen Intel(R) i3-12100F, NVIDIA RTX 3070, 31.20 GiB of DDR4 memory. Backtrace generated by following the ardour bug reporting guide via GDB is attached below. In case more information is needed I am happy to provide.
