This is a quick demo of the Sequentix Music Systems Cirklon sequencer.

A few patterns thrown in to see if I can capture the pretty lights accurately on video. Green looks a bit washed out.

Beat position sweep fades from bright green thru orange to red then off, on tri-colour LEDs.

LEDs below each track pulse with note output velocities controlling colour – green for max, and fading thru red again.
