Can anybody tell me how to program the AY-*-* sound chip built 
in the ST?  It looks rather difficult to me to do this via the 
Giaccess() call every time, cause it's hard to tell which 16 
bit number plays a middle C.
Maybe someone could explain how the xbios-call do_sound() works. 
I'm writing on a music application which plays sheet music, but 
should also be able to use the simple synthesizer possibilities
of the sound chip, such as attack, hold, continue, vibrato.

Anyone knows about the AMY sound chip that is being developed 
(when it's coming out, prize, etc.)?  I became very curious
when I heard about it's the great features, which can concur
with professional synthesizers.
