Arturia - Keystep Pro

The KeyStep Pro is both a 37-key MIDI controller and a multi-channel, polyphonic sequencer. It allows modular rigs, outboard synths and software studios to be controlled simultaneously. The four independent polyphonic sequencer tracks give you full control over the instruments.
The first track can also be used as a drum sequencer with 16 parts.
