Thx, Dude!

Decided to drop by as I had already been looking in these things (Matrix 1000 does it similar way as MKS-30 I happen to own).

I didn't locate High Speed clock in the Matrix schems (well, I only had a quick look), but in a MKS-30 it is an LC osc (this is where the tuning takes a place, inserting a small random fluctuating voltage would probably make it more analog sounding ::) ) which is then buffered, going to pre-scaler (4-bit counter, probably used for octave switching) and then to the 8253s.

8253s handle generating pitch, (including pitch bends and 2nd osc detune), before the waveform converter.

One last note: These DCO driven waveform converters aren't going to produce nice sawtooth or triangle waves for many octaves without active compensation of the waveform converter. You'll see a note in CEM3396 datasheet about that.
