Mine arrived about 30 minutes ago. Fabulous looking piece of kit, available at Schnieder's. 16 Alps faders - 16 * 5v or 10v faders (each can be individually set) ... MIDI and I2C outputs.., activity/power light. Available as a kit, or of course you can bake from scratch on GITHUB.... but I wanted a pro-build. And it is!
Comes supplied with lovely desktop case (which I will use), Euro power cable, USB cable (power), mini-jack to MIDI cable and I2C cable. So yes, euro rack fit, but quite large, and so I will use it out of rack. Best really, as the point is to control your euro easy without the rats-nest getting in the way.
Can't believe this hasn't had more coverage... Now to go and play. I'm sure it is just what the doctor ordered
