[sdiy] new to list with some questions

[Scott Gravenhorst]

Thomas Henry's 8038 Linear VCO ("Neat Linear VCO" on the same site)
would also work and has tri, sine and square outputs, a nice
complement to the FatMan's sawtooth VCOs.  This VCO also does not
require a tempco resistor or any matched transistors.

If you want to use Tom Henry's VCO1 with a FatMan, you will have to
use the Linear FM input for pitch CV.  The 1v/oct input won't scale
correctly with a FatMan's linear Pitch CV output.
