Fresh, customizable aesthetic
Want your sequencer-controller to stand out with a slick, futuristic edge? KeyStep Pro Chroma puts a metallic sci-fi spin on the original design, featuring an electrifying metallic gray exterior, metallic knob caps, vibrant blue LEDs, and customizable track colors.

Evolved sequencing, arpeggiation, and looping

Performance-oriented read more
Enjoy a sequencer that's designed to be hands-on, immediate, and expressive. Switch tracks in seconds, configure each to create sequences or arpeggios in real-time, save and recall groups of sequences, and tap the looper strip for breaks, fills, and glitches to add variety and randomness.

Next-level connectivity
Connect and control every part of your setup, from Eurorack modules to VST instruments, totally in sync. Make the most of 4 x CV, Gate, and Mod outputs, 8 dedicated drum Gate outputs, clock in/out, MIDI in/out, and much more - everything you'll ever need.
