Ardour 6.2.0 crashes when importing a MIDI file

Installation & Configuration Linux
#1

I’ve tried many times to import MIDI files into Ardour 6 and Ardour quits instantly. I’m on Ubuntu 16.04.
The file loads perfectly into Ardour 4. Any suggestion?

Please file a bug report, ideally attach the .mid file that causes the issue
at tracker.ardour.org – Thanks.

Does it always crash with any midi file, or just some specific files?

The following ones work here with Arodur 6. Might be useful for a quick test:

I could load your files “notesweep.mid” and “velocitysweep.mid” without a
problem, but Ardour crashes when loading your file “mf_Beethoven5.mid”.
I’ve tried other MIDI files I have, some load and some make Ardour crash.

Here’s one file that makes it crash. It’s a very simple MIDI file, 2 piano
tracks. It loads fine in Ardour 4, which I have been using for quite some
time and I love it, but I wanted to test Ardour 6.

Thanks for your help!

(Attachment auclaird.mid is missing)

#5

You cannot attach .mid to an email response, but have to upload it somewhere (e.g. google-drive, drop-box or similar) and then link to it.

OK, here’s the link to my MIDI file :

It loads OK into Ardour 4.

#7

It also loads and plays just fine here in Arodur 6.0 and 6.2.
What synth plugin are you using when importing the file? Can you try setting that to “-none-” to rule out that it’s an issue with loading multiple synths.

PS. I’ve tested with general-midi synth (comes with Ardour 6).

#8

The file will open in Ardour 6 when selecting “None” for the synth. Once
loaded, if I try to select a synth plugin the program quits instantly.

At least, I can use Ardour 4 to use MIDI. I am using Ubuntu 16.04, which is
a few years old. I wonder if it could be a factor?

Thanks again for your help.

Aha, so it’s a problem with the synth. – Which synth plugin are you using?

#10

I have tried with a-Reasonable synth and also Calf Fluidsynth, but both
crash the program.

Thanks,

Henri

#11

I could see calf plugins causing cashes, but a-reasonable synth?

Ubuntu 16.04 in general should be fine, except perhaps some issues with (older) plugins.

The only way to get to the bottom of this would be with a debug build (demo is fine) https://nightly.ardour.org and getting a backtrace: https://ardour.org/debugging_ardour

Today, I turned on my computer and I tried again to load the MIDI files
that made Ardour 6 crash and now EVERYTHING WORKS FINE! It was as simple as
restarting the computer.

I’m sorry for the trouble it may have caused you and thanks again a lot for
your help.

Today I was trying to import a MIDI file into Ardour 6.3.0 and, again, Ardour crashes (quits). I can open the file if I select “None” for the instrument, but it crashes when I select a synth. I tried to restart the computer like I did in July, but it didn’t work this time. Again, the file opens fine in Ardour 4.

P.-S. I downloaded the Debug version of Ardour 6.3.177 and the MIDI file opens and plays fine.

P.P.-S. Ardour 6.3.0 also quits when I try to open a file created with the debug versioin.

#14

Three months later, I have the same problem importing MIDI files with Ardour 6.3.0. Strangely, the debug version works fine, so I cannot debug the problem. Ardour 6.3.0 also quits when opening files created with the debug version.
