[sdiy] Buchla Lowpass Gate Switch

[Fernando de Izuzquiza]

Anyhow, I think it could be great to redesign the control section (and 
use it with the B or C audio section)


I don't know how-to though...

I imagine a circuit that puts out 0-20mA (I think max is 30mA for the 
5C3) for 0-10V with a series LED so you have an indication if you like.
Before that, it can be good to have an input circuit where you can +/- 
scale and offset the incoming CV.

May be with a switchable expo mode. May be you can control "more or 
less expo" in an easy way.


This way we can explore the cv response and have all control options 
available. Or decide a final configuration/s and build the module/s 
with the control response you like.
