MIDI-CV-Arpeggiator Prototype

This is a live demo of my MIDI-CV-Arpeggaitor prototype, demonstrating many of the real time features. It's driving my Paia 9700 modular. I have the aux CV out connected to the filter cutoff on the Paia.

This board is now in full production. See the [KRM-90] MIDI-CV-Arpeggiator retrofit board page for full details.

It also comes as a full Eurorack module, with an LCD screen. [KRM-100] MIDI-CV-Arpeggiator Module

To prove you are not a robot, what is 1 plus 2?
