Supplier's Notes:
Professional standalone sequencer

Genuine centerpiece of a setup, it offers every tool needed to compose songs in the studio and perform them on stage. From vintage to modern synths, from modular systems to your favourite DAW, Hapax can sequence and synchronize all your gear, while bringing you carefully crafted tools, designed for maximizing creativity.

The midi powerhouse.

Up to a million notes and events

16 tracks per project, 8 patterns per track.

Thanks to its dual-processor architecture, Hapax can record and transform tremendous amounts of data in no time, without a hitch.

Express yourself.

MPE compatibility

Hapax is the first hardware sequencer that fully supports MIDI Polyphonic Expression. Record the finest gestures, slides and articulations of your playing, without compromising quality.

Around the clock performance.
Dual-project architecture



Hapax can handle two separate and independent projects, that can be played simultaneously. This lets you compose or load an entire project while the first one is already playing, enabling endless sets and seamless transitions.

Dawless is more.

Hapax offers broad connectivity options for perfect integration in any setup.

Adaptive workflow.
Several ways to write music
Writing a melody: use a polyphonic or MPE track and take advantage of the advanced step sequencer to quickly lay down notes or edit your live recording.

Composing a beat: control up to 8 different instruments with a single track. The drum sequencer is tailored for very easy rhythm writing and jamming.

Real-time midi effects.

Bring your synths to life

Hapax embeds multiple real-time, polyphonic, non-destructive midi effects, as well as project-wide assignable LFOs. Each parameter of these effects can be automated in the dedicated mode, and processed in the mod matrix, which provides even more ways of routing and modulating.

Powerful composition tools.

Algorithms

Powerful tools for offline note transformation and generation, right at your fingertips. Harmonically invert your motive, generate a controlled-random counter-melody, slowly ramp up the velocities, emphasize every fifth 8th note...

Hi-res recording

Hit the red button, and record from the encoders and 128 pads of Hapax, external midi instruments (included MPE controllers) or any incoming analogue signal, at a high resolution of 192 ppqn. Looper style recording, count-down and metronome options, punch-in mode, you'll certainly find the options that best suit your workflow.

Time elasticity

Each track has an elasticity value which changes its playback speed, expressed in percentage of BPM. Quickly double or halve the speed of a track, or create slightly shifted tracks that will slowly drift out of phase with each other.

Fluid editing

Using hardware should never get in the way of creative flow. The undo / redo button lets you go back in time as needed, thanks to its extensive history. Additionally, the snapshot function enables you to save the state of a pattern and recall it with a single press. Together with dedicated copy, paste and delete buttons, Hapax offers a complete toolbox for the prompt editing of your tracks.

Harmony, simplified

For fast and intuitive chord building, the chord live mode brings harmonic capabilities to anyone, with or without deep theoretical knowledge. With its colourful interface, the chord mode displays a synesthetic melding of hearing, vision and touch.

Simple by design.

Trimmed to perfection

Squarp designed Hapax from the ground up, deconstructing everything you thought you knew about sequencing- aiming for a high-end product, with dual arm processors for computation power and a rugged yet minimalist housing.

As music-making should remain an enjoyable process, dedicated buttons were over key combinations and imagined a clear-cut interface as well as a simple architecture. Squarp have striven to minimize the importance of screens for live performing, but the dual grayscale display helps keeping track of things in a studio context.
