Custom changes made to the config after first initialization got lost
after setting work directory. Therefore moved custom initialization into
a separate function which is called after setting work directory.
On non-Linux platforms configuration file was saved in the application
path which definitely is not desired and also will not work in many
situations. Therefore always save ZynAddSubFX configuration file in
LMMS working directory.
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.
