Unable to Set Soundfont for Fluidsynth-DSSI

Hello,

I'm having trouble with the fluidsynth-dssi plugin in Qtractor. In particular, when creating a new track to use it, the little panel doesn't show the option to choose which soundfont to use. See the first pic, below.

Not being able to set the soundfont, means that I get no sound. By the way, this is on my studio laptop which runs under Linux Mint 22 Xfce.

However, my upstairs laptop, which runs under Linux Mint 20.3 Cinnamon, brings up the panel as expected. See the second pic, below.

As you can see, this panel lets me choose the soundfont.

I'm basically a novice at this sort of stuff, so can any of you experts suggest a solution? Thanks.

Thomas Henry

I've never used any of the DSSI plugins but would suggest you try the Calf FluidSynth LV2.

Thanks for the suggestion, but it gives me the same results: the Calf Fluidsynth plugin panel is once again barebones, with no way to indicate the desired soundfont. So, no sounds, of course.

Moreover, on the Mint Cinnamon laptop, it's even worse: the Calf panel comes up in a totally blank window.

Also, I forgot to mention that I'm using Qtractor 1.3.0 now.

hi,

some probable reasons for the problem you're having:

  • fluidsynth-dssi is not fully installed, especially its GUI counterpart (FluidSynth-DSSI_gtk);
  • gtk2 and gtkmm2 runtime libraries are not installed, also blocking the above fluidsynth-dssi_gtk component;
  • qtractor built without the support to the above gtk2 and gtkmm2 development libraries, which is prolly the cause for the Calf suite having no GUIs.

hth. cheers

Calf GUIs are not visible in the appimage version.
What is the reason?
I guess it's because it looks for its libraries "/lib/calf/" inside the "tmp" that the appimage generates and doesn't find them.
Just curious.

Thank you very much for your suggestions, Rui. I still haven't figured out the difference in behavior on my two computers (the older Cinnamon runs the Fluidsynth-DSSI plugin nicely, the newer Xfce doesn't), but I'll keep experimenting by following the leads you kindly supplied. I'm fairly new to the Linux world, but do enjoy learning and am always up for some detective work.

In the meanwhile, here's a work-around in case anyone else is having a similar problem. I stumbled upon the Ardour-LV2-Plugins in the Software Manager. It includes a fluidsynth module which works very well in Qtractor. In particular, it opens up with a panel letting me set the soundfont to be used.

So, with this, I'm back in business. As a recap, on one of my computers Fluidsynth-DSSI doesn't let me choose a soundfont. But the Ardour supplied LV2 one works just fine instead.

And while I'm at it, a big thanks, too, to you Rui for all your hard work on Qtractor! It really is an excellent program, easy to use and producing professional results. I truly appreciate your generosity in sharing it with us all.
