>I sink the VCO/VCFs current in the transistor that has the control
voltage applied. This is the same as the Formant and the ASM-1 I think.
But the minimoog VCO uses the second one, with the op-amp's feedback
going to the first.

Sorry, this is the wrong way round. But the question remains the same.
What advantages are there in doing it either way?
