Steve,
Your description of this oscillator sounds exactly like the master
oscillator in an old EML Synth package I used to own - It was called
the Electrocomp 200 - In the top left corner was this oscillator with
a Big knob - 10 turn pot - a rotary switch was used to switch
octaves, and it put out simultaneous square, sine, and triangle
waveforms. There is a photo of this system at synthmuseum.com. - just
rang a bell.
