Modifications:
Custom LED Colors: This Klee been modified with Bi-Color LEDs so Stage LEDs 9-6 are green when the sequencer is in 2X8 mode. Blue LEDs on Random and Bus 2 Status. Yellow LEDs on Rate and Bus 1 Status. Green LED on Bus 3 Status. Red LED on Main Bus Status.
The Klee is the most feature packed, crazy, beautifully insane sequencer out there. Every option is implemented in this layout. Once you get one the Klee in your rack, you'll wonder how you managed without it. It can function like any other 16 step sequencer out there, or it can function like it has a brain of it's own. Easily programmed with your own ideas, or flip the Random Switch and find out what "it" has in mind. An endless source of inspiration.
This is one BIG build. Save yourself the time, hassle, and inevitable troubleshooting by purchasing this Klee fully and professionally assembled by Free State FX.
The Klee, pronounced Clay, is a shift register based sequencer. What makes the Klee different from most sequencers is that more than one Stage/Step can be active at any given time.

With the Klee, one or more stages can be active at one time, the CV programmed by the active Stages is added together, and is then sent to the CV Out..."
