The Catwalk Ribbon Controller is Waveform's DIY Project #4. This attaches in a new way to your Eurorack system by going over top of existing modules and therefore taking up no extra HP. Super fun, kinda weird, and very touchy feely, this uses an LFO, offset, or something of the sort to power it, and we think it's the cats pajamas. Faceplate is black with silver.
