ABOUT
Now you can CV your SNR. DIYSNRCVA. Do It Yourself Simple N Radical Control Voltage Adapter. It's simple, two headers (middle connector is cv in, outer connector is ground - orientation insensitive) and two jacks.

There two variables, thus four options:
pin cables with 6.35mm jacks (parts)
pin cables with 3.5mm jacks (parts)
socket cables with 6.35mm jacks (parts)
socket cables with 3.5mm jacks (parts)

Using the SNRCVA:
Send it stuff at around 0-5 Volts. I didn't measure the voltages in the video below, I'm just sending 0-max voltages via my MOTU 828 II FW. Works fine. (But, see some safety stuff below.)


INSTRUCTIONS

SAFETY
The Radical Chip (PIC12F1840) has built in protection diodes. It wants 0-5V, sending a bit outside that won't kill it, but there is no point doing it on purpose. You can still destroy the diodes, they aren't magic.
This adapter is passive, e.g. whatever you send is summed hard with the voltage coming from the pots (uness you add a resistor in series - hack away). It works fine with CV from an audio interface - the pots affect the result. Turning the pot to the extremes will probably clip or just delete the CV/audio you are sending.
Have fun. Noise is not about control.
