@starrlabszone This is a Clipper-DX5 with an IR proximity detector set up to control the clock rate for the LED lighting script that's running on the fingerboard. The hardware is set up as a MIDI ContinuousController that is sending a "Clipper-control" MIDI message to the embedded LED controller. The sensor can be setup to control anything really. Pitchbend is the most common of the FX and how it's often used. It's a custom option available on any of our instruments. www,starrlabs.com
