KeyStep mk2 is the ultimate compact controller & sequencer for hybrid setups. With a 32-note Slimkey keyboard, generative sequencing tools and deep connectivity via CV/Gate, MIDI DIN, and USB-C - spark ideas in your DAW, pilot any synth or patch modular without breaking your flow.

Step into your next idea

KeyStep mk2 is more than keys. It’s a sequencer, arpeggiator, and musical nerve-centre that bridges hardware and software so you can compose, jam, and perform anywhere your ideas take you.

Hands-on control

Play, arpeggiate, and sequence ideas the moment they strike. KeyStep mk2’s OLED display, clickable encoder, and full RGB feedback also make every edit fast and intuitive.

Generative creativity

Capture a riff, turn it into a sequence, then transform it with mutation tools and real-time performance control. Keep inspiration flowing with features that invite constant discovery and movement.

Universal connectivity

Command modular, vintage, and modern gear alongside your DAW. CV/Gate, MIDI DIN, Sync I/O, and USB-C keep every piece of your setup talking, and in time.

Control & sequence anything

From sketching a melody to shaping full arrangements, KeyStep mk2 keeps ideas on the move. Every touch, twist, and note responds instantly, letting you build, evolve, and perform without interruption.

Slimkey keybed: 32 expressive keys with velocity & aftertouch.

16 mode arpeggiator: From simple cycles to creative melodic textures.

Pitch & mod touch strips: Smooth bends and modulation plus live Gate/Spice/Dice sliders.

OLED display: Clear, immediate parameter feedback and editing.

Mutate, Spice & Dice: Instant, musical variations and controlled randomness.

Assignable CV/Gate outputs: Four outputs for pitch, gate, and modulation to control modular gear.

Polyphonic step sequencer: Record or program up to 64 steps of 8-note polyphony.

Chord & Scale modes: Lock to a key and trigger full chords for harmonic flow.

Full-size MIDI DIN + Sync I/O: Seamless DAW, hardware, and Eurorack integration.

Inspiration on command

Your workflow’s best friend, KeyStep mk2 plays like an instrument, edits like a groovebox, and invents like a modern synth. Trigger and edit patterns on the fly with an advanced sequencer and arpeggiator. Overdub notes, record automation in real time, transform grooves mid-flow, and perform without breaking tempo.

3 modes total control

KeyStep mk2’s modes work in synergy to keep ideas evolving - capture a riff, turn it into a sequence, mutate it, and keep the momentum alive.

Sequencer mode

Create and play back polyphonic patterns. Chain, overdub, undo, mutate, automate bends/mod, and transform sequences live - great for hardware rigs and sketching ideas in your DAW.

Arpeggiator mode

Choose from 16 arp types including Poly, Walk, Pattern, and Random. Phrase Arp remaps your sequence to played notes for immediate, musical mutations.

Controller mode

With MIDI, USB, and CV, KeyStep mk2 handles it all. Use it as a central controller to sequence gear, input chords, or modulate CV synths from one compact keyboard.

Every port every possibility

KeyStep mk2 is your universal creative interface. Patch into modular systems, control synths from past and present, and synchronize your drum machines. Ready to command any setup - live, in the studio, or on the move.

Digital & analog, unified

Full-size MIDI DIN I/O for classic hardware, USB-C for DAWs and soft-synths, and assignable CV/Gate for modular.

CV for modular minds

Four CV/Gate outs mappable to velocity, aftertouch, mod-wheel, and more. Patch lines, open filters, ping envelopes: expressive control.

Sync, sustain & convert

3.5 mm Sync In/Out for vintage gear, TRS sustain/expression input for feel, plus MIDI In → CV to play modular from external keys.
