[sdiy] synth chip

[patchell]

    There was also the GI 8910/8912 (Sorry, I don't remember the exact
part number, it was something like AY-?-8910)

    If you are ambitious, and you would have to be very ambitious, you
could build a digital synth chip into either an Altera or Xilinx FPGA.  I
have not actually done this, yet, but you can get an amazing amount of
stuff into one of those.  Also, you could go the DSP route.  The
Motorolla 56303 has a lot of horse power and you can implement a pretty
nice synth in one of those (Clavia has demonstrated this with their Nord
series).

    But, as far as analog synths on a chip...we are probably out of luck
on this score.  Aliesis, of course, has their Andromada, which is all
analog, and since Aliesis just recently bit the big one, we might
(although, I doubt it), see these chips show up on the surplus market.
