[sdiy] Octave Cat SRM2

[David Holt]

Well, I'm sure my list may change when I get the thing in my hands, but just off the top of my head:
-CV control of the VCA since there's no LFO routing there
-CV control of the Oscillator's pitch (individually)
-A patch point between the filter and VCA, for extra or replacement filtering
-CV control of filter frequency

I may do nothing, but I know that Octave had a set of factory mods they did, and I was hoping that someone had ended up with the schematics on that.  They had all kinds of interesting mods including patch points, adding pink noise, an HPF, and many others.

Usually adding inputs and outputs is very simple, the hardest part is adding 
the sockets. Yesterday I added an audio input to the 8 filters in my 
dw-8000, since this is fairly simple and no one has any reference to this 
mod online I might put up some instructions.

To do CV mods properly you should add buffers to protect against heavy 
loading, but even then it's very simple. What do you want to add patch 
points to?
