Yamaha CS80

My study of the IG00153 VCO is here:

http://www.cs80.com/vco.html

The output ofthe 153 is a sawtooth. The output of the 158 is the
inverted sawtooth. This is what goes to the filters through a FET gate.

The pulse waveform is pretty regular as it is a simple comparator-type
circuit inside the IG00158.
