Adaptive Workflow
Multiple ways to create.
Write melodies with polyphonic or MPE tracks, using the advanced step sequencer to sketch ideas or refine live takes with surgical precision.

Build beats using a single track to control up to eight instruments. The dedicated drum sequencer makes rhythm writing immediate, playful, and inspiring.
Real–Time MIDI Effects
Bring your synths to life.
Hapax features a suite of real-time, polyphonic, non-destructive MIDI effects, enhanced by project-wide assignable LFOs. Every parameter is automatable and fully routable through the modMatrix, unlocking complex, evolving modulation, without ever altering your original performance.

Chord mode
Harmony, SimplifiedBuild chords fast and intuitively. Chord Live Mode brings harmonic capabilities to anyone, with or without formal theory. Its colorful interface creates a synesthetic experience of hearing, vision, and touch, making chord exploration immediate and inspiring.
Hi–Res Recording
Hi–Res RecordingHit record and capture performances from Hapax’s encoders, 128-pad matrix, external MIDI instruments (including MPE controllers), or any incoming analog signal, at 192 ppqn resolution. Looper-style recording, countdown, metronome, and punch-in modes let you tailor the workflow exactly to your needs.
Fluid Editing
Fluid EditingHardware should enhance creativity, not get in the way. With undo/redo, an extensive history lets you travel back in time. Snapshots save the state of a pattern for instant recall, and dedicated copy, paste, and delete buttons complete a comprehensive editing toolbox. Everything you need for quick, precise workflow.
Time Elasticity
Time ElasticityEach track has its own elasticity, allowing playback speed adjustment as a percentage of BPM. Double or halve speeds instantly, or create subtle, drifting phasing effects between tracks — perfect for dynamic grooves and evolving textures.

Simple by Design
Trimmed to perfection.
We reimagined Hapax from the ground up, deconstructing everything we knew about sequencing. The result is a high-end instrument built around dual ARM processors for uncompromising performance, housed in a rugged yet refined minimalist chassis.

Because making music should always feel effortless, we chose dedicated controls over complex key combinations, and shaped a clear, intuitive interface supported by a streamlined architecture. While we designed Hapax to minimize reliance on screens during live performance, its dual grayscale displays offer just the r ight amount of visual feedback when composing in the studio.

Hardcore industrial techno live performer, producer and DJ

Iʼve used a lot of sequencers and the Hapax is to me, the end game sequencer for live performance. The built in modulation capabilities, dual project feature, and many many midi outputs are what sold me on the Hapax.

I also love the active user community on the Squarp forum and how frequent the Squarp team rolls out updates and takes into account feature requests.

At the moment, I donʼt think thereʼs another sequencer that does as much as well as the Hapax which is why I use it as the brain of my live set.

The Hapax is the centerpiece of my hardware rig. It supplies the clock and the majority of the sequencing for my entire rig. Itʼs greatest strength is that it serves as the master conductor of the my setup allowing me to send program changes that change the patterns on all of my other sequencers.

My music is more alive and dynamic than it ever has been since I started using the Hapax. The workflow feels like an extension of myself and it is a source of instant inspiration every time I turn it on.

Mr Tuna

Hardware-only synth musician and video artist

The Squarp Hapax is the single most important piece of gear in my studio-- I always dreamed of a device that lets me play and record all my synths live and on the fly and there's nothing that works better for me than Hapax!

It makes me a better musician. It's so easy to create exactly what I want and it always sounds like me. Multi-track MIDI recording on the Hapax is incredible! I can arm the whole studio to record and create intricate music loops with separate tracks and effects. Its how I always envisioned creating music! I host over 30 devices across 2 projects and every midi in and out on hapax-- It syncronizes and sequences everything flawlessly and is the device that lets me create music the way I want to.

Ben Walker

Producer and musician

The Hapax has become the brain of the studio - everything, old MIDI gear and drum machines, new synths and modular, integrates with it. I can sketch, loop, rearrange, be surprised... it brings it all together.

Eric Nyffeler
Portland, USA
Experimental producer, art director at Chase Bliss

Hapax gives me the power to write and perform songs exactly how I imagine them in my head, with no concessions, compromises, or settling. The combination of the pad matrix along with two screens gives me as much control as I could ever want without feeling that I'm spending all my time squinting at a computer screen. The grid matrix makes writing drum parts almost comically fast; fast enough to jam in real time with other musicians! The four midi outs, along with the logical and immediate UI, makes it incredibly easy simultaneously connect a wide range of gear, allowing me to almost instantly bounce a melody or rhythm.

Colleen
Barcelona, Spain
Composer of electronic and ambient music

For my live shows for my album "Le jour et la nuit du réel", I needed a sequencer that would be capable of handling extremely long sequences in song form (more than 7 minutes) and could also send these sequences unquantized, all this with a clear layout and a relatively easy learning curve, as it was going to be my first sequencer ever. The Hapax has delivered all of this, and even better is the fact that I know this is just the tip of the iceberg when it comes to its capacity to make sequencing an in-depth, adventurous process. I plan to use it for my 9th album during both the recording process and live shows, and anticipate it will stay in my setup for years.

The Hapax has significantly enhanced my ability to create more complex and engaging sequences, largely due to its algorithms and MIDI effects, which offer endless possibilities. There's an impressive array of tips and tricks to uncover. Itʼs truly transformed my workflow, especially with the ability to control my hardware synths and Eurorack systems while staying perfectly synchronized with Ableton Live. Managing hardware used to be a challenge, but since getting the Hapax, everything works seamlessly.

Captain Pikant & The Intern
Video & music creators

We love to use the Hapax on our channel. It's very intuitive to work with and a great tool to visualize and understand patterns. We find the zoom levels and dual project features super helpful - and it's fantastic to have two screens and so many dedicated buttons!

Brise Lame

Electronica & IDM producer, member of RiCO le collectif

It's a war machine that I use to sequence my modular system, Ableton, and my generative visuals in TouchDesigner. I needed a sequencer that could easily handle multiple inputs and outputs, with an efficient interface that emphasizes composing and performing without disrupting my creative workflow. The Hapax does just that—whether in live performance or in the studio.
