The Arturia KeyStep Pro is a 37-key MIDI controller, polyphonic step sequencer, and performance hub in one unit. Four independent polyphonic sequencer tracks can each drive a different synthesizer or drum machine over MIDI or CV/gate, and 16 velocity-sensitive drum pads handle beat programming and finger drumming. The 37 slim keys with aftertouch provide expressive note input, while clock in/out synchronizes with external gear. Dual MIDI outputs, four CV/gate output pairs, and USB connectivity make the KeyStep Pro a central routing point for hybrid hardware and software setups.
