Oh, I just got a 16F87 ICD kit to pull
this off with. ;) Uart, A/D, etc etc..
All sorts of goodies..

Now I just need to get a decent i2c or
serial D/A to do some LFOs with too..

It will prlly go up as freeware code and
the person will be able to configure the
core by enabling modules of the code to
get what they want. This simple
midi/sequencer/LFO generator will be the
core for a synth add-in module I am
working on that will be able to go into
nearly anything, with low power and all.

Maybe just midi clock in, run a simple
16 step sequencer where you get to pick
one of three events that go out D/A 1
(gate, note, or trigger), and you get to
pick a synced LFO and clock division of
some sort for D/A 2 (saw, ramp, square,
tri).

I guess I could do it with 1 D/A and a
couple of clocked sample and holds,
which is prlly the way to go.
