fluidsynth-dssi not restoring after session save/load

Forums

Hi Rui,

I'm having a couple of issues with qtractor and qjackctl with an install on a new machine. I'll post the qjackctl issue separately in its section of the forum following this.

When opening the fluidsynth-dssi gui via the Mixer, it's displayed correctly and I can load a soundfont and change options. The soundfont also plays correctly. However, when I re-open the gui all information has been reset to default - no soundfont loaded, default options. Even so, the audio still plays correctly - it's just the gui that's been reset. Something similar happened a couple of years ago.

When reloading the project via File > Open Recent, the audio is still OK (but gui still reset to defaults, as before). However, after making an arbitrary change (e.g. solo/unsolo a track), saving, then reloading via File > Open Recent, no audio will play. i.e. Qtractor/fluidsynth-dssi seem to remain in the "audio playing" state only until the session is altered and re-saved/re-loaded.

FYI, when closing the GUI I get the below in Qtractor's messages, but I've had this for ages so I imagine it may not be relevant to this:

(FluidSynth-DSSI_gtk:6310): GLib-CRITICAL **: Source ID 7 was not found when attempting to remove it

I've attached 2 simple qtz files:

1) fluidTest_pre.qtz: after initially loading the soundfont/changing options
2) fluidTest_post.qtz: after making a change in the session and resaving the session

You'll see that, in fluidTest_post.qtz, the configs area (at least) has the patch etc. info missing.

I got the packages from your https://www.rncbc.org/archive/:

libfluidsynth-devel-2.0.3-15.rncbc.suse.x86_64.rpm
fluidsynth-dssi-1.1.0-4.rncbc.suse.x86_64.rpm
fluidsynth-2.0.3-15.rncbc.suse.x86_64.rpm

I also have a libfludsynth1 (1.1.11-lp150.1.1) installed, which was pulled in by YaST (I'm on opensuse like you) when I installed lv2-calf. Is there any problem with having both this and your libfluidsynth2? I tried temporarily uninstalling it but it made no difference to the above problem.

I'm running the latest git version of qtractor.

Thanks as ever.
