The Kawai & Teisco Analog Synths Group

I don't have the service manual anymore (went with my 240 when I sold it) so I can't say exactly what they're doing. The only SSM chips are the filters (2044).

 I believe since there are only square/trailing edge saw waves available its digitally generated. Its fairly easy to make a square wave into a saw with waveshaping. And the square is native to the digital domain.

 Thanks Travis. The DCOs are non-discrete, correct? I.e. they are on chips like the SSM2044s? Are they digitally-controlled analog oscillators (i.e. Six-Trak) or are they fully digital? I have read both facts in different places. Are there eight oscillators?

 Many thanks,
 James

I will be ordering a replacement battery and diode soon; the synth starts up with a hanging note but otherwise is a joy to play.
