[sdiy] MIDI DCOs

Has anyone come up with a DIY, MIDI controlled, DCO bank? Something like 
8 DCO's that will polyphonically follow MIDI and send out a 
corresponding Gate with each note on.

I envision something like that with a Wiard Miniwave after it, that 
could be used to build a DCO based (no tuning problems) poly synth along 
the lines of a Juno 106, but with whatever waveshaping, Filters, VCA's 
and envelope's you want.

Or something like the Buchla Octal Signal source which is a DCO bank 
with, as far as I understand it, a wavetable lookup system. In this case 
3 DCO's per voice with software controlled wavetables. But, maybe 
something like this could be made with Miniwave technology and have it 
all under voltage control, but the notes follow MIDI.

Could you take something like a Paia MIDI to CV and tap off the digital 
words before the D to A and send that to something like Ken Stone's DCO 
and then trigger the resets of some ramp generators, controlling the 
ramp speed with the CV out? This is only 4 voices though.

Or is hacking a Roland MKS-30 or similar the best bet.

There are lots of you digital guys out there, this just seems like it 
should have been done by someone.  Is there no demand for such things? 
This seems like the bridge between the analog and digital worlds to me. 
Of course I know nothing about software code.
