thanks alot tolkien - it does really work
the resulting outputfiles i can extract with fmconvert.
trouble is - after successfully writing the outputfile with FmSynthDX7.exe it does a guru (8100 0005) everytime.
tested on A1200 setup ( winuae only here - kick/wb 3.0 030/882 2chip 64 z3 fast - JIT on/off makes no diff).
