OBERHEIM SYNTH

Hi Jose

you were not wrong. The CEM3396 can not oscillator by itself.

And a DCO always consists from two components.
1.) a digital controlled divider (8253 or 8254) provides the clock
2.) a waveform shaper creates the waveform from that clock and a CV

In the M6 or M6R the clock is created by a 8254 and the wave form is 
shaped by the CEM3396

The official name of the CEM3396 in the Curtis Datasheet is "uP 
CONTROLLABLE DUAL WAVEFORM CONVERTER / PROCESSOR".
