Wow, thanks so much, Fox! I don’t fully understand this, but hopefully I can stretch my brain. Otherwise, if someone can put together detailed instructions for assembling / modifying Cadet V to get these results, I think it would be helpful to other users who are competent with soldering but lack electronics knowledge.
There’s a wide array of Eurorack audio hardware out there, and no standard voltage ranges.
I also have The Analog Thing on pre-order, and its voltage range is also +/- 10v.
