My prototype REFM module (WIP)

REFM stands for “random enough for me”
2 8 bit shift registers, each with an 8 bit DA and buffer ICs (CV1 and CV2)
Instead of white noise I use a 2.5Mhz (ish) ring oscillator for data.


No idea what’s going on but it sounds bleepy and weird.

Is this a standalone box or a modular panel?

At 2:10 of the first video you see the breadboard. At present it is in the
experimentation stage.

I could build it into either a standalone or a module.
As I have no eurorack, I will likely build it as a one-off.

I have a fair amount of semi-modular gear though,
so I more than likely keep it for modulating all the sem-modulars.
