neutron control voltage mods?

I've had a Neutron pcb partially populated, sitting around for a few months and I'd like to keep working on it soon.

Are there any existing mods for control voltage inputs and/or outputs on this pedal? For example, an envelope signal brought to an output jack? or perhaps a switched cv input which would disconnect the envelope and permit insertion of an external voltage?

thanks much for any mod info...

I can only speculate. Maybe one could take a Neutron board, isolate the place where the rectified/filtered signal went in, and then diddle that point with an external voltage source to discover what voltages made it work well. Sounds like a pleasant afternoon with a lab bench to me.

In response to the questions in the forum - PCB Layout for Musical Effects is available from The Book Patch. Search "PCB Layout" and it ought to appear.

Hey RG- this looks like a fun project! Thanks for your comment

For the voltage control input, another option would be the old "jack attached to vactrol attached to your potentiometer" method of kludging CV into circuits...but the conditions for this are particular...this would not disable/switch off the existing envelope, it would be in parallel.

The control voltage envelope output might be the easier mod...if I can figure out a pad where the envelope voltage could be brought to a jack...somewhere after the LDR's ...hmmm.

well I'll build it stock, I am putting the cart before the horse, but if anyone has additional ideas, they are appreciated...
