Just looked into the Noise Reap Paradox, and jep you're right. It's more than just a VCO. Looks and sounds frigging nice. I'll contact them today if they currently ship to the EU/Germany, as a lot of people have shipping issues right now.

I switched out the unity Panning Mixers form your build and added these 2hp ones as the PCB and front available at pushermann. Seems like mouser has everything I need in stock, too but I need to check local suppliers too.

It's probably a good idea anyway to have some wiggle room for the time I'm still in my jumpskiff.
