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 modMatrix, which provides even more ways of routing and modulating.

Algorithms

Chord mode
Harmony, simplifiedFor fast and intuitive chord building, the chord live mode brings harmonic capabilities to anyone, with or without deep theoretical knowledge. With its colorful interface, the chord mode displays a synesthetic melding of hearing, vision and touch.
Hi–res recording
Hi–res recordingHit the red button, and record from the encoders and 128 pads of Hapax, external midi instruments (included MPE controllers) or any incoming analog 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.
Fluid editing
Fluid editingUsing 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.
Time elasticity
Time elasticityEach 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.

Trimmed to perfection
We designed Hapax from the ground up, deconstructing everything we knew about sequencing. We aimed 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, we favored dedicated buttons over key combinations and imagined a clear-cut interface as well as a simple architecture. We 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.
