In Hapax, algo (algorithms) are operations that are not performed in real time, but rather applied "offline", directly on the sequences you programmed or recorded.
When working in step or automation modes, press algo to enter this submode.
Select the algorithm by scrolling encoder ① and Press it to apply the algorithm on the pattern you are working on. The other encoders let you configure the algorithm parameters.
Some parameters have a secondary value that can be accessed with a Hold + Rotate of the associated encoder.
Tip Make a selection before applying an algorithm to only alter the selected zone.
Generator
Availability: step POLY tracks step DRUM tracks
This algorithm replaces the existing notes with a new randomized pattern. Generated notes are quantized to the specified grid. The min & max pitch, velocity and length of the new notes can also be adjusted. Lastly, it is possible to set the amount of events (density %) and to decide whether the generated notes are monophonic or chords (mono ... poly 4).
QUANTIZE 1/1 ... 1/64 Rotate encoder ⑥ to set the grid on which the generator will place the generated notes.
LENGTH 1 ... 64 Rotate encoder ③ to set the maximum note length of generated notes, in steps. Hold + Rotate encoder ③ to set the minimum note length.
VELOCITY MIN/MAX 0 ... 127 Rotate encoder ④ to set the maximum velocity of generated notes. Hold + Rotate encoder ④ to set the minimum velocity.
DENSITY 0% ... 100% Rotate encoder ⑦ to set the density of notes in the generated pattern. Hold + Rotate encoder ⑦ to define the polyphony: Mono Only one note can be created per time division. Poly 2 / 3 / 4 Enables chord generation (polyphony).
PITCH C0 ... G10 Rotate encoder ⑧ to set the maximum pitch of generated notes. Hold + Rotate encoder ⑧ to set the minimum pitch. Note This option can only be accessed from POLY tracks.
This algorithm modifies note parameters by applying a curve on their values. The waveform (sine, triangle...), its min & max amplitude and its rate can be adjusted. By default, the modified note attribute is the velocity, but other destinations can be set (length, chance...).
For example, a ramp applied on velocity will result in a "velocity fade in".
WAVE SINE TRI RAMP SQUA RAND PERLI Rotate encoder ③ to set the waveform of the curve. The last parameters RANDOM and PERLIN, which are two types of random generators, have extra parameters that are described below.
AMPLITUDE Depends on destination Rotate encoder ④ to set the upper value of the curve amplitude. Hold + Rotate encoder ④ to set the lower value of the curve amplitude.
DESTINATION Rotate encoder ⑥ to set the note parameter to modulate: PITCH Pitch VELO Velocity LENG Length CHAN Chance ROLL Roll MATH Math condition uTIME Micro timing
REPEAT x1 ... x128 Rotate encoder ⑦ to set the number of repetitions of the selected waveform in the selected zone.
STEPS INF 1 ... 256 Rotate encoder ⑧ to downsample the curve using a fixed number of steps. INF has the best definition, calculating new values for each steps.
⨁ PHASE -180° ... 0° ... +180° Note Click on REPEAT to access this parameter. Rotate encoder ⑦ to offset the curve by adjusting its phase.
⨁ SEED -- 0 ... 9999 Note If RANDOM or PERLIN selected, click on STEPS to access this parameter. Rotate encoder ⑧ to choose a seed for the random curve. A specific seed will always produce the same curve, that can be reused to obtain the same controlled random modulation.
⨁ VALLEYS 0 ... 100 Note If PERLIN selected, click on STEPS twice to access this parameter. Rotate encoder ⑧ to adjust the level of peaks and valleys to the curve.
Shuffle
Availability: step POLY tracks
New! This algorithm shuffles the notes in several ways. There is a mode where you can shuffle individual notes or note parameters between themselves called STEP . The other mode, called PART , segments the notes in equally spaced partitions and shuffles them. In both mode, there is a probability parameter that controls the probability of each note or interval to be shuffled, allowing for partial shuffling.
As usual, selecting a zone before applying the algorithm will only shuffle the selected zone. In the PART mode, the interval starts at the selection start. Events at the end and outside a whole multiple of the partition size, will not be shuffled. In addition, the algorithm doesn't take into consideration the micro time parameter, which means that negative micro timing at the very start of a partition will be considered as in the previous partition.
MODE Rotate encoder ③ to toggle between the two modes. STEP Sets mode to shuffle individual notes or note parameters. PART Sets mode to shuffle note segments.
PROBABILITY 0% ... 100% Rotate encoder ④ to set the probability of each note or segment to be shuffled.
DESTINATION Note This parameter is only available in STEP mode. Rotate encoder ⑦ to set the note parameter to shuffle. ALL Shuffles all note attributes simultaneously. KEYS Keys VELO Velocity LENG Length CHAN Chance ROLL Roll MATH Math condition
INTERVAL 8BARS ... 1/64 Note This parameter is only available in PART mode. Rotate encoder ⑦ to set the interval at which notes will be shuffled.
Symmetry
Availability: step POLY tracks
This algorithm flips events horizontally (time) or vertically (pitch). The original events can either be kept or replaced.
MODE TIME PITCH Rotate encoder ③ to toggle between horizontal and vertical symmetry.
DUPLICATE OFF ON Rotate encoder ④ to enable the superposition of the generated notes onto the original notes.
Every N
Availability: step DRUM tracks
This algorithm creates evenly spread notes with accents and ghost notes, based on the N parameter. Very powerful for sequencing drum sounds. Beware of the wild grooves you'll end up with.
GRID 1/1 ... 1/64 Rotate encoder ③ to adjust the grid on which the generated notes will be placed.
N 1 ... 16 Rotate encoder ④ to set the accent placements on the grid. With N = 2, every second note in the pattern will be accentuated.
ACCENT VELOCITY MIN/MAX 0 ... 127 Rotate encoder ⑦ to adjust the maximum velocity for each accent.Hold + Rotate encoder ⑦ the minimum velocity.
GHOST VELOCITY MIN/MAX 0 ... 127 Rotate encoder ⑧ to adjust the maximum velocity for each ghost note.Hold + Rotate encoder ⑧ the minimum velocity.
