Hi, trying out appimage 0.16.4 on Ubuntu Studio 20.04. Starts ok. Enable logging to file, save, restart. Enable Jack for audio transport (not midi yet), save, close. On attempting to restart, I get a seg fault.

Maybe I'll try an older appimage and see what changes. I also have 0.15.4 installed from the distro's repo (issue: viewtopic.php?f=2&t=1590)

What else do you need?
Thanks!

Did some more testing, and actually made some good progress with 0.16.1... farther than I got with 0.15.4.

0.16.2, ~.3, and ~.4 all seg fault.

Thanks!

Sorry, I missed this one.
Anyway, this is a known bug and has been fixed, so the upcoming version 0.17 will be free from it.
A workaround exist. The reason for the segfault are the "-1" values stored in giada.conf file. Change these to "0" and it should work.

BTW I also had MicroKEY, great piece of gear you got there.

Microkey is not horrible

By the way, 0.17 still seg faults.

Changing the -1 to 0 allows it to start. I have not been able to validate if it is functional beyond that... perhaps in the next day or so.

Thanks!

By the way, 0.17 still seg faults.

Does it segfault with the old giada.conf in place, or after you let it create a new one?
0.17 version should create valid conf files, but still might segfault if the config has been broken by an earlier version.

Starting fresh, it wrecks. Just re-verified. I tried setting it to Alsa, and that doesn't break. Just Jack (well, I didn't try anything other than Jack and Alsa).

Thanks!

Thanks for pointing that out, I thought this problem has been already fixed. Gotta reopen the github issue!
