I’m trying to load the ACE Fluidsynth plugin in Ardour 8.4 but for some reason it doesn’t seem to work. I tried opening Ardour via terminal to try to catch some error message but nothing is logged. Adding the plugin to a track freezes Ardour.
I’m using it on Ubuntu 22.04 with Pipewire. If it helps, I was using Calf Fluidsynth over Ardour 7.0 until yesterday on the same computer.
Debug log
I tried running Ardour with the --gdb flag but no interesting additional output was shown. Only these lines:
Can you add the plugin directly when creating a new MIDI track?
No. Same thing happens: Ardour freezes. I just checked that the same issue occurs if I try adding the ACE Reasonable Synth instead. Also, I just checked that Ardour is using the correct version of the plugin (the one bundled with Ardour 8.4).
Ok, it seems like I can’t add any MIDI plugin. The same issue happens with other plugins like Podolski and Triple Cheese (from U-he). But the same plugins work from Carla or even Ardour 7.0.
Not using pipewire (I hope).
Yesterday I also could not invoke the Gui of Ace fluidsynth. Also one time I had Ardour crashing when I doubke clicked the plugin.
Temporarily switched back to 8.2 to keep going.
Will recheck when I’m at the machine.
Not sure if pipewire is running somewhere under the hood, a process “pipewire” exists.
How do I know for sure what’s going on?
Is there an easy way to get rid off it? Should I upgrade (don’t want to mess up the system)
Also version 0.3.4.8 currently
The symptom
I have a midi track. ACE fluid synth instantiated.
Now I open the plugin, open the file browser to select a sf2 file and … crash
Maybe it has something to do with the file browser
I installed Fluida as a work around, but Ardour 8.4 also crashes when I try to open the file browser and select a SF2 file
How to reproduce (on my system)
create a new session
add a midi track with ACE Fluidsynth
open Plugin GUI
click on file select
crash
fluidsynth: warning: No preset found on channel 0 [bank=0 prog=34]
fluidsynth: warning: No preset found on channel 9 [bank=128 prog=0]

Segmentation fault (core dumped)

Ok, could I find out what the annoying icon file could be?
Any other workaround except going back to 8.2 loading the SF2 file,
opening with 8.4?
Editing a file in the plugins directory?
DaD does not work, cause the plugin GUI disappears when I go to Dolphin
EDIT:
Just read the ticket history. from that I assume there’s not a lot I can help to debug.
If I can please let me know. For me loading SF2 files is kind of essential
EDIT2:
because it works in 8.2 and it does not in 8.4, does it have something to do with the gtk2?
It’s probably not the same issue, especially if Paul has concluded that it is an icon error, but the Hydrogen drum machine had a similar crash-on-opening-file-browser and that was due to some translations being to long for the size of the buttons they were attached to.
If your system is set up for something other than English, try starting Ardour from the command line with LANGUAGE="en_US" LANG="en_US" /path/to/your/Ardour
and see if it makes any difference
