ZynAddSubFX has gained some new developer power so development has been
going on well for quite a while now in their Git repo. It's time for
the first big resync so future changes can be integrated easily.
OscilGen::tmpsmps and OscilGen::outoscilFFTfreqs were static member
variables initialized once in LocalZynAddSubFx class. However having
this data global is not a good idea because it gets modified by each
synth (possibly in parallel), causing heavy distortion under various
circumstances. Now that this data is allocated and used per-synth
everything works fine.
Added a new GUI-less mode to ZynAddSubFX instrument plugin which allows
to let ZynAddSubFX audio processing happen within LMMS, giving a much
better realtime behaviour.
As soon as showing up the GUI settings of GUI-less ZynAddSubFX instance
are saved and a traditional RemoteZynAddSubFx process is being launched
and the settings are applied there.
