Row Octave (Octave Tree)

Purpose

Program per-row octave movement with two layers:

LHS: an immediate base octave for each row
RHS: an octave tree sequence for that row

The octave tree has 8 slots. Each slot lasts for 4 playback steps, so the full RHS pattern covers 32 steps. During playback the engine uses slots 1–4 on even bars and slots 5–8 on odd bars, so the row’s pitch register evolves across the cycle instead of staying at a fixed octave.

Interaction

This view has a deliberate split role:

LHS edits the row’s base octave. A press there updates that row’s octave setting immediately.
RHS edits the row’s octave tree. Each pad represents one 4-step block of the sequence, so the 8 RHS pads together cover 32 playback steps.

The sequenced octave values on the RHS are added on top of the base octave from the LHS. Reset/randomise use the pressed row; the row can be selected from the grid or from Row mutes. A row plays at its base octave plus the current slot’s value plus the sequencer octave, each octave being 12 semitones.

Exact LED layout is documented in Octave tree.

Shortcuts

LHS: base octave

Gesture	Where	Action	Modifiers
Press	LP LHS	Set the pressed row’s base octave immediately	none

RHS: octave tree sequence

Gesture	Where	Action	Modifiers
Press	LP RHS	Set one 4-step octave-tree slot for the pressed row	none

Whole-row gestures

Gesture	Where	Action	Modifiers
SHIFT + MUTE + press row R	LP grid	Reset row R: base octave → 0, all 8 sequence slots → 0 (flat)	shift+mute
SHIFT + SOLO + press row R	LP grid	Randomise row R: base octave → random −3…+4; each sequence slot → random −4…+4	shift+solo

Sequencer-level octave (all rows at once) is set from the LC: SHIFT + top row = up, SHIFT + bottom row = down (see Global controls reference).
