I'm getting strongly distorted audio when using
fluidsynth-dssi in any host (tested with ghostess and
qtractor) and suspect this to be related to that dssi update
until proven wrong. Strangely, all other dssi plugins
including the updated ones from some days ago work like a
charm, as does fluidsynth played via qsynth.
Since you're not the only one, let's see what you have in
common. Versions? Distros? Did you compile
fluidsynth-dssi after the DSSI upgrade, or are you using a
pre-DSSI-upgrade version?
Pedro Lopez-Cabanillas tracked the problem down and posted a bug
report against fluidsynth-1.1.2.
Downgrading to 1.1.1 makes the noise in fluidsynth-dssi disappear.
It is appearing when fluidsynth 1.1.2 is configured with more than
1 stereo channel.
So no dssi problems :)
Thanks, Pedro and I have been corresponding. Until a fix is
available, you can either downgrade to fluidsynth 1.1.1 (as you
said), or you can compile fluidsynth 1.1.2 to use floats instead of
doubles, either by adding '-Denable-floats=yes' to the cmake command
line, or by using the autotools build system, which defaults to floats.
