[Bug 34831] Re: Hardlock of entire system (Dapper Flight 5)

[Alberto Torres]

I suggest you Qsynth as sampler, you need soundfont (.sf2) files to use
it. It is not limited to 8mb as your soundcard, the limit is your RAM.

Also I suggest ZynAddSubFX as softsynth, it comes with a lot of nice
instrument presets. It doesn't need RAM for soundfonts, but CPU power
for synth emulation.

Qsynth is a gui that uses fluidsynth underneath, which follows the soundfont2 specs very accurately.
I don't know of any timidity gui to configure it (it requires command line arguments), also timidity is rather old and not very useful for modern soundfonts (it was designed for GUS patches). I think that the only advantage of timidity over fluidsynth is that it loads the instuments on-demand instead the entire soundfont file, but it is annoying when it delays an instrument because it's loading.

Do the module unloading-loading trick and open zynaddsubfx, qsynth or
timidity before opening rosegarden. Please tell us if it works or not
for you.

I'm not a kernel dev, I hope someone tell us how to help tracking the
bug.
