More Questions:
It is NOT GENERAL MIDI (as far as I know).
Does this thing play back SMFs?(because it
does not say so in the literature)
If it does, can it play both Type 0 and
Type 1 files?
Can it read files directly from disc, or have 'load while playing' capability like the newer WK2 models?

George, Are you selling the WS1 or WS1D(with
floppy drive)?
Please email the price you are asking, since I may have someone interested.
Thanks
