Appendix VIII - Logical Grouping of Parameters

ARP’s parameters (in SET Mode) are laid out across the note and chord buttons in a way that makes them appear equally important. Indeed, They all have a role and function in shaping the sequence and its behaviour.

However, there is a logical flow to the sequence creation. Understanding this flow may be helpful in understanding what each parameter does and how they work together to create wonderful music.

It must be noted that the order in which parameters are configured has no impact on the sequence that ARP generates.

ARP is deterministic, so a given set of parameter values will always produce the same result.

ARP recalculates each current step as if the current configuration was in place since you first pressed play.

See ARP's Deterministic System

Parameters by Group

  • Basic Setup

    • Mode - play notes sequentially or simultaneously

    • Midi Out - which MIDI Channel to send

      • Voice Mode - polyphonic or monophonic

    • Velocity - how loud notes are played

  • Sequence

    • Steps - how many intervals to play from the Chord/Scale

      • Pitch Filter - limits the number of Chord/Scale intervals used for the sequence

    • Bounce - how to move through the Chord/Scale intervals

    • Direction - order that bounce intervals are played (TODO: This needs it’s own appendix)

    • Offset - start position of the sequence

    • Jump - skips over Chord/Scale intervals

  • Pitch

    • Octave - offsets the root note (relative to the Global Octave) by multiples of 12 semitones

      • Lock - overrides Global Octave

    • Note - offsets the root note by Chord/Scale intervals

      • Offset Mode - offsets by semitones, if is set to Chromatic

      • Note Lock - overrides selected root note

      • Scale Lock - overrides selected Chord/Scale

      • Limit - prevents notes being played too far from the root note

cont…

  • Timing

    • Gate - length of individual notes

    • Time (Division) - how many steps are played per bar

      • Factor/Function - how changes to Time Division are applied

    • Delay - adds time before playing notes

    • Chop - sets the number of times a note plays within an individual step

  • Repeats

    • Repeat - number of times steps are played before playing the next step

    • Ratchet - number of times steps are retriggered

  • Patterns

    • Rhythm - pattern modulation of Velocity

    • Groove - pattern modulation of Delay

    • Binary Patterns - pattern modulation of Velocity, Delay, Chop and Ratchet

  • Modulation

    • FX - pseudo-random pattern based modulation of various parameters

    • Mod A/B - wave/shape based modulation of almost all parameters
