Anyone have a MIDI to Mockingboard
compatible converter?
MIDI.CVT on my web site reads MIDI files and allocates a bank
of "oscillators" to the notes. It can handle a dozen or more
oscillators simultaneously, and it outputs a "music" file which
is a set of <note,duration> streams for each oscillator. It
could be massaged into a program to output time-merged instructions
to set up '891x chips (although, that's basically what MIDI is,
so maybe this trip wasn't necessary ;-).
How many channels are available for sound
output through the MB?
3 per sound chip--6 on a typical Mockingboard--plus one
noise channel per chip, possibly good for snare drums.
I'm also looking for a library of voice definitions
for the MB.
As already noted, the AY-3-891x sound generator is basically
a squarewave device. There is envelope control, but it is always
unmistakably "square", so "voices" are quite limited.
