* versions:
* (14): adapted to latest code base
* (13): ???
* (12): fixed voice stealing
* (11): fixed arguments of fluidmax_tuning_octave() (third has to be float)
* (10): added micro-tuning methods
* (9): bug fix: now polyphony and # of midi channel arguments take effect
* (8): added message resample permitting to chose resampling interpolation method
* (7): added names for soundfonts (== file name without path and postfix)
* (6): added message 'info'
* (5): fixed bogus path translation at file loading
