Sequencer workflow


Hapax can load and play two projects (proA, proB) simultaneously. Each project has 16 tracks.


Each track has its own inputs & outputs, its own FX rack and a set of 8 patterns.


A pattern is a loop that contains polyphonic or monophonic notes and/or automation. Each Pattern has its own events, length, runmode, effect parameter values, ...
Working with projects
Projects proA and proB are accessible directly through their dedicated button. Each of them contains 16 tracks and can be played at the same time.

For smooth transitions you can seamlessly load a project on proB while proA is running for never ending live sets!

Press  proA  or  proB  to select a project.

Hold  proA  or  proB  to enter project settings (left screen):

... and also enter the save/load menu (right screen):

Selecting and configuring a Track

Hold  2ND  and rotate encoders to scroll faster.
Routing midi inputs & outputs
Hold  track  to enter track settings :


Every note of the track, whether coming from the built-in pad matrix

, the sequencer or an external keyboard, will be outputed on this port and channel.


Input port : sets up which port the track is listening to.

Input channel : sets up which channel the track is listening to, depending on the choosen port :
  • "--" : the track isn't receiving notes from any port.
  • "all active" : the track listens to all input ports, only when this track is active.
  • "midi A" / "midi B" / "USB Device" / "USB Host" / "CV/Gate" : the track only listens to the selected port. This setting is always active, even when the track is not selected.
Quick tour of the 4 modes
Hapax is designed around 4 main modes :
 live  mode : use the 128 pads as a scale keyboard or as a chord generator (to change the livemode, hold live and rotate the menu encoder).
 step  mode : use the 128 pads to add or fine tune notes (or drum events) with surgical precision.
 automation  mode : use the 128 pads to create midi (or fx) automation.
 pattern  mode : perform in sync by using the 128 pads to set the playing pattern of each track. Create sections (group of patterns). Chain sections to build a song.
Step mode essentials
Press  step  to enter the Step mode.

Press any matrix pad
pads icon
to enter a note.

Press it again to delete the note.

Left screen parameters contains the default values for a note. Any newly added note will inherit those values:

The upper-left parameter is the note displayed on the pad matrix's bottom row. By rotating the corresponding encoder, you can scroll up and down in the piano roll view. A viewport on the screen frames the notes displayed on the matrix pads :

Selection: Hold a Step already filled with a note to finetune any parameter. You can also select multiple notes at the same time.
