ODP: 'Hybrid' Synthesisers

[Roman Sowa]

don't know Wave, but if you're interested, can tell about my poly
i made a while ago.

Master VCO drives 12 semitone 8-bit dividers.
12 frequencies go to each DCOs which select one of them and 
octave division.
5-bit counter outputs control waveform RAM (8-bit DAC)
And there are 8 of them.
waves can be single (32 samples), multiple (4k) or looped
(4k and loop on last 32 samples).
It sound nice but forget about sine whistles etc
- imagine 1kHz sampling frequency at low keys

Awesome zoundz come out of it when in single mode
with random or noise wave in RAM, but as i call it
with external frame change - LFO switches RAM pages
(32 sample waves) through 4k (128 waveforms) of entire RAM.
I didn't realize what i've done until i played it.
