[sdiy] VCO - sine output - why bother?

[Steve Ridley]

Hello Donald (and list)

> The Aries VCO, designed by Dennis Colin (who was responsible for much of the early ARP synths), did something very similar. 

The dual core thing goes right back to the ARP 2500. Take a look at the 1004 VCOs. Triangle (square/pulse/sine) VCO and a saw VCO - each had it's own expo sub-module, and it looks like the triangle reset the saw. 

Dennis worked for ARP - so I guess that's where it came from.
