Arturia - 'KeyStep 37'

total creative control
Arturia’s newly released ‘KeyStep 37’ is much more than a simple-to-use 64-step sequencer, arpeggiator and MIDI keyboard. It’s hugely responsive, widely dynamic and has been expanded in every direction to spark musical exploration. Arturia’s ‘KeyStep 37’ is the controller that’s built to inspire.
It’s the same familiar KeyStep formula, just expanded. KeyStep 37 boasts a velocity-sensitive 37-note keybed, featuring aftertouch and RGB LED feedback, all this, whilst remaining super lightweight and highly portable! At the heart of the control panel, you’ll find 4 new knobs with a new LED screen, offering quick access to creative and expressive tools and MIDI tweaking – sheer creative control.
