I saw this thread on FM synthetizers hardware details and got a doubt
about
the software :
I tried the same code with my MSX-Audio (ports #C0 & #C1) and got the
same
results. Then it's also capable of generating interrupts, just like
moonsound
does. Is there any known software for moonsound and MSX-Audio that uses
the
IRQ/OPL timmers for timming instead of the VDP IRQ ?
Cya MSxers ...
