I'm slightly confused as well. The dedicated VCA (own input and
output & cv control) on the NJM2069 is used for the white noise
only. I assume that the EG3 (Depth determined by White Noise
mixer level) is inputed into this VCA's CV input. The output of this
VCA (Pin 10) then is externally routed into the NJM2069's VCF
audio input (Pin 19).
Now what i am confused about is the terminolgy of a voltage
controlled mixer VS. a VCA. Both control the Amplitude of an
audio signal from a CV source, right? So aren't the VC mixers on
the NJM2069 just VCA's who's outputs are internally routed into
the VCF? Assuming that these are Log CV inputs (Pin 2&3),
couldn't you amplitude mod Osc1 & 2 by rerouting the LOG CV
output of the onboard LFO into these Pins ?(buffered LFO CV
output comes from Pin 14 of "IC7").
Better yet, would be to mount patch points on the Poly 800 as CV
inputs/outputs, another potential CV input would be for the
resonance (which is Voltage Controlled), imagine the pleasure
of modulating the resonance from EG3 or the onboard LFO or
external CV generators....yummy!
