Design your own DW8000 synths?

Check out the waveforms on the Korg DW-8000, an early wavetable synth. What
we (analoggers) need is a good wide range high-frequency VCO. Then we could
do someting like it. The waves mostly do not sound like sine, triangle etc.
Run the VCO at 16x (32x?) the desired fundamental and read waves from RAM /
ROM. Hard-sync by counter reset.
Why not just use a computer?
Because: The fundamental reason for the "analog" sound IMHO is that the
oscillators are continuous waveforms... even though we may turn notes on and
off with VCA, or filter. The waves are continuous, they don't "retrigger"
every time you hit a key. Think of instruments like woodwinds or brass, they
don't always retrigger, the air is still vibrating as you shift from one
vibrational mode to another. I think I can tell the difference between a
wave that is retriggered and one that was still oscillating. (I may, of
course be hallucinating). :-) Harry Bissell
