Hi there!
I just made this shit short video of my first attempt at controlling my DEP2a with a light dependent resistor.
The CV is controlling the threshold above which the sample looper records the audio input into its buffer. I set it to record when I hover the resistor.
It works quite well, I only have to make some proper controller with cool sensors and get more gear with CV inputs :)
