If I remove all except the first two jack midi ports from the untitled project, and save, then crashtestdummy won't crash anymore when loaded after untitled, so that's a clue...

Edit: eh, once it didn't. Now it crashes again...

Nah. I don't think those jack ports have anything to do with the crash. Deleted them all, and it still crashes. Disabled "read midi port config" when loading projects: still crashes.

Opening 6 JACK MIDI in and out ports is the default, at least on my system with the MusE config removed. My JACK has system -> midi_capture_1 2 and 3 / midi_playback_1 2 and 3, as well as a2j's Midi through and the two actual MIDI devices (in and out each). So the default for MusE is to open ports for each of those.

I have this line in my config file:
<configure_midi_ports>0</configure_midi_ports>

I only get Alsa ports by default (though not auto-enabled).

In my QjackCtl/post_startup.sh I have (among other things) -

Code: Select all

a2j_control --ehw && a2j_control --start

Which starts up the a2jmidid thingy that automatically creates JACK MIDI ports for all ALSA MIDI ports.

I prefer to be known as a figment of the 'nets imagination, living in the future, waiting for the rest of you to catch up.

What happens if in crashtestdummy you disable "show project description at startup"?

in its med, set:
<showinfo>1</showinfo>
to
<showinfo>0</showinfo>

Solves the crashes here!

But why does it crash only after it is loaded after your co-supplied untitled.med, and only when that project is loaded as the first project in MusE?

If I load a project of my own, then load untitled, and then load crashtestdummy, it doesn't crash. Also, if I load it as the first project: no crash. If I load it second, after a project of my own: no crash either. It also doesn't crash if you load untitled twice before loading crashtestdummy.

I've reproduced the crash. I'll make a new thread with info.

Working on more (re)loading crashes, hang in there. I'll have something soon.
The (re)loading stuff still isn't quite right.
You'll get those messages above and maybe crashes.
Some pre-existing bugs there (not mine).

Still in the realm of stability and trustworthiness before moving on...
