KeyStep 37 Mk2 MIDI/CV Controller

Arturia KeyStep 37 Mk2

Arturia's Keystep 37 Mk2 is a versatile keyboard controller that can connect to your computer, desktop synths, and modular gear with ease. You can play it like a regular keyboard, but with the built-in sequencer, you can treat this as a robust musical expression device capable of inspiring and surprising you. New Mutate, Splice, and Dice options let you create generative patterns from sequences and arpeggiator patterns.

Chord and Scale modes let you easily compose elegant chord progressions and shred without worrying about a missed note. For devices and software that have a lot of controls that are sans knob, the 4 encoder interface allows you to control 4 banks of CC values without jumping values. A class compliant and low power USB-C connector lets you power the controller from a computer, standalone synth, or mobile device without taxing the PSU at all. Expressive and flexible, the KeyStep 37 Mk2 from Arturia is the controller you'll be coming for time and again.
