PLAN B analog blog

You're welcome, Tom!  Thanks for the support.

Your conjecture on replicating the overtone structure of an external
audio band ac signal is spot on, however won't do the trick here. 
Once you see the basic flow of the M30 you'll see the VCAs come after
the processing.  SO while you could get a digitized rendering if you
will of an external waveform that way, it would come after the
Frequency Shifter.  Here is the basic M30 flow diagram, it'll make it
much clearer:

SO the only way to do it is how I mentioned earlier, and yes there
will be some harmonic distortion due to scaling of the VC Freq inputs.

in as far as M32, thanks for your enthusiasm.  I will post some sound
samples which will explain how cool the Kinetic gates are. Until you
'see' them in action it's hard o put your arms around the concept.
