AppleWin doesn't have the most subtle sound emulation.  ;-)

Apple II Oasis sounds pretty good (sort of), but doesn't completely
emulate the n-key rollover keyboard.

Emulators are pretty hit and miss on how they deal with ultrasonic
pulse-width modulation.  ;-)

Much different, as Simon reports.

I'm happy to provide additional motivation for folks to run
real Apple II's.  ;-)

It works fine on a IIgs (at least in slow mode--I just realized that
I've never tried it in fast mode.  ;-)

Of course, there are other options for the IIgs.  Hasn't anyone
implemented an ensoniq-based synth supporting the IIgs keyboard
for piano-style playing?
