Best overall: Arturia KeyStep Pro. It combines a playable 37-key controller with four polyphonic sequencer tracks, drum sequencing and unusually broad MIDI/CV connectivity. Novation’s SL MkIII is the better choice when full-size keys matter more than portability. Arturia’s KeyStep 37 Mk2 suits smaller, simpler rigs. If you can supply your own keyboard, Squarp Hapax delivers substantially deeper sequencing; Synthstrom Audible Deluge is the strongest all-in-one groovebox alternative.
A keyboard sequencer is more than a MIDI keyboard with an arpeggiator. It stores patterns, records notes live or step-by-step, routes them without a computer and normally provides editing, synchronization and pattern recall. The shortlist below separates integrated keyboards from standalone sequencers and grid-based instruments so you do not buy the wrong kind of workflow.

What counts as a keyboard sequencer?
An arpeggiator generates a repeating note pattern from notes you are currently holding. A pattern sequencer records and recalls notes after you release the keys. A multitrack keyboard sequencer does that across several parts, with independent MIDI or CV routing, while a standalone sequencer supplies the sequencing but requires an external keyboard or pads. A groovebox adds its own synthesis, sampling or audio performance; a DAW controller only sequences through computer software.
For this guide, a serious keyboard sequencer has internal pattern storage, live and step recording, editable musical events, clock synchronization and hardware routing. Track count alone is not enough: four well-routed polyphonic tracks can be more immediate than a larger system hidden behind menus.

1. Arturia KeyStep Pro: best overall keyboard sequencer
What it does
Arturia specifies a 37-key velocity- and aftertouch-sensitive keyboard, four independent polyphonic sequencer tracks, a 24-part drum sequencer, arpeggiation and sequences of up to 64 steps with up to 16 notes per step. Its MIDI, USB and CV/gate facilities let one compact unit address hardware synths, software instruments and modular voices simultaneously. Details are listed by Arturia at the official KeyStep Pro page.
Why it wins
- Dedicated track and pattern controls make live creation, muting, transposition and recall fast.
- Polyphonic MIDI sequencing and separate drum sequencing cover a compact hardware setup without a computer.
- Four CV/gate/modulation output groups and eight drum-gate outputs make it unusually useful with Eurorack and semi-modular gear.
- Chord, scale, arp, looper and randomization functions encourage performance rather than menu programming.
Limitations
The slim keys are a compromise for anyone expecting a primary piano-style instrument. The small display is less visual for detailed editing, and four melodic tracks can constrain a large multitimbral arrangement. Sound On Sound’s review also identifies the slim keyboard and limited MIDI-control approach as potential drawbacks for serious keyboard players: review coverage.
Buy it if: you want immediate DAWless control of several synths or modular voices. Skip it if: full-size keys or workstation-style song arrangement are non-negotiable.
2. Novation SL MkIII: best for keyboard players
Why choose it
SL MkIII is the keyboard-first counterpoint to KeyStep Pro. Its full-size keyboard options, pads, faders, templates and studio-controller design make it better suited to a player who wants one central instrument for manual performance, hardware sequencing and DAW control. It is a stronger fit for hybrid studios and multitimbral setups than a compact slim-key controller.

- New creative features: Scale Mode, Chord Mode, and Arpeggiator, making composition, songwriting, and beat-making more intuitive than ever.
- Custom DAW integration: KeyLab Essential mk3 features custom scripts for deeper control over DAWs, including Ableton Live, Logic Pro X, FL Studio, and more.
- More versatile presets: The 2000 presets included with Analog Lab Pro are no longer limited to vintage sounds; users can enjoy unique hybrids, modern synths, orchestral sounds, and more.
- Easier controls & interface: RGB-backlit pads with velocity and pressure sensitivity, contextual buttons, and a bright new 2.5” LCD screen for real-time feedback. Expanded software package for beginners & pros: Now includes Analog Lab Pro, 2 pianos (UVI Model D, NI’s The Gentleman), plus subscriptions to Loopcloud and Melodics.
Trade-offs
The larger chassis is less convenient on a small desk or in a travel rig, and its workflow is less deliberately compact and performance-centric than KeyStep Pro. Verify the current model, firmware, software support and regional price on Novation’s site before buying: Novation.
Buy it if: the keyboard itself is your main instrument. Skip it if: minimum size, extensive modular routing or a dedicated sequencer feel are your priorities.
3. Arturia KeyStep 37 Mk2: best compact/value choice
Who it suits
The KeyStep 37 Mk2 is the simpler entry into onboard sequencing: a portable keyboard with sequencing, arpeggiation, chord and scale functions and hardware connectivity. It is appropriate for beginners, travel rigs and users sequencing one or two external instruments.
What it gives up
It does not target the KeyStep Pro’s routing depth or large hardware arrangements. Slim keys remain less satisfying for piano-oriented playing, and arrangement capacity is lighter than on Hapax, Deluge or a DAW. Arturia’s current product page should be checked for the exact Mk2 specification and price at Arturia; a reliable current price is not established here.

4. Squarp Hapax: best professional standalone alternative
Sequencing depth
Hapax is not a keyboard controller. Squarp lists two independent projects, 16 fully polyphonic tracks per project, 16 patterns per track, four MIDI outputs, two MIDI inputs, four CV outputs, four gate outputs, MPE, 192 PPQN recording resolution and automation for MIDI CC, pitch-bend, aftertouch, program change, NRPN and CV. Track lengths range from one step to 32 bars. The current specification and €1,080 listed price are on Squarp’s product page.
Who should buy it
Choose Hapax for complex MIDI routing, MPE, detailed automation, structured songs and live pattern manipulation. Budget for a separate keyboard, controller or manual note-entry method, plus the necessary power and MIDI adapters. It is excessive for a one-synth beginner setup.
5. Synthstrom Audible Deluge: best all-in-one alternative
What makes it different
Deluge combines sequencing with synthesis, sampling, audio looping and standalone performance. It offers a 128-pad grid, more than two million listed notes, up to 16 MIDI channels subject to CPU limits, two CV outputs, four gate/trigger outputs, MIDI over hardware or USB, an internal speaker and more than six hours of listed battery life. The manufacturer lists NZ$2,299 with applicable import taxes and tariffs included: Deluge product page.
Who should buy it
It is ideal when you want one battery-powered instrument for songs, samples, looping and synthesis. It is not a replacement for a conventional piano keyboard, and it is poor value if you only need MIDI sequencing.

Connections that determine the right purchase
- Five-pin MIDI: the most dependable way to connect hardware synths and avoid USB-host confusion.
- TRS MIDI: check whether Type A or Type B adapters are required.
- USB-MIDI host versus device: a device port can connect to a computer but may not control another USB-only instrument without a host box or compatible hub.
- CV, gate and modulation: confirm pitch-voltage standard, gate polarity, voltage range and the number of independent voices before connecting modular equipment.
- Clock and transport: test clock, start/stop and pattern-change behavior separately; select one clock master to prevent loops.
- Pedals and MPE: sustain, expression and MPE support vary and should be checked against your controller and instruments.
How many tracks do you need?
Four polyphonic melodic tracks can cover bass, chords, lead and an additional part in a compact rig. Eight or more tracks become valuable for layered performances, multitimbral instruments and full-song arrangements. Count drum parts separately, and remember that a standalone unit may offer more tracks while requiring a separate keyboard. A device with fewer tracks can still be faster live if each track has a dedicated button and predictable pattern recall.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Live performance and editing checklist
- Can you switch patterns, mute tracks and transpose without stopping?
- Are changes quantized musically, and can you undo a mistake?
- Does it offer live and step recording, velocity, gate, microtiming, probability or conditional triggers?
- Can it save chains or songs and recall them instantly?
- Are automation, pitch-bend, aftertouch, program changes and MIDI files supported where you need them?
- Is the display readable and the common action reachable in one or two physical moves?
DAW integration and a reliable first setup
Every shortlisted device can be part of a DAW workflow, but standalone operation does not mean self-contained: you may still need a sound source, mixer, power supply or external keyboard. In a DAW, choose one clock master, then test note data, clock, transport and program changes independently. MIDI feedback and double-triggered notes usually indicate a routing loop or duplicate monitoring path.
- Connect MIDI or CV from the sequencer to one sound source.
- Set the MIDI channel or CV voice and select a single clock master.
- Record a short pattern live, then make one step edit.
- Save the project or pattern before adding another device.
- Test stop/start, pattern switching and program changes.
- Add further instruments only after the first route behaves correctly.
Who should not buy a keyboard sequencer?
- Players who require weighted full-size piano action.
- Producers who need deep audio recording, mixing and a visual piano roll more than hardware control.
- Users who only need an arpeggiator or chord mode.
- Anyone expecting a workstation sound engine, arranger accompaniment or large display.
- Buyers who specifically require Elektron-style per-step parameter locks; support varies and should not be assumed.
Bottom line
Choose KeyStep Pro for the best balance of playable input, polyphonic patterns, drums and modular connectivity. Choose SL MkIII when full-size keys and studio control come first. Choose KeyStep 37 Mk2 for a smaller, easier setup. Choose Hapax when sequencing depth outweighs the need for an integrated keyboard, and Deluge when you want a complete standalone music-making instrument.
Frequently Asked Questions
Can a keyboard sequencer work without a computer?
Yes. It can send MIDI or CV directly to hardware, although you still need a sound source and, for some standalone sequencers, an external keyboard.

Is an arpeggiator the same as a sequencer?
No. An arpeggiator reacts to notes being held; a sequencer records, stores and recalls note patterns.
Can these devices control Eurorack?
KeyStep Pro and Hapax provide CV/gate facilities, but confirm voltage range, gate polarity, adapters and the number of independent voices for your modules.
What is better: KeyStep Pro or SL MkIII?
KeyStep Pro is better for compact hardware and modular performance; SL MkIII is better when full-size keys and a central studio keyboard matter most.
Do standalone sequencers include keyboards?
Hapax has a pad matrix but no conventional piano keyboard, while Deluge uses grid note entry. Plan for an external keyboard if you want traditional playing.
