Trig

Purpose

The central editing surface and default view for every sequencer. Write which steps fire, set per-step percentage chance, conditional (mod/inv-mod) and sustain trigs, overlay Euclidean patterns, and set each row’s play mode (UNMUTED / LEGATO / DRONE / MUTED).

Interaction

8 rows (row 1 bottom → row 8 top) × 16 steps: LHS LP columns 1–8 are steps 1–8, RHS columns 1–8 are steps 9–16. Each cell’s colour shows its trig status (OFF, ON, PERCENTAGE_CHANCE, TRIGMUTE, MOD1–MOD16, INVMOD4–INVMOD16, sustain). LHS column 9 is the row mute button for each row. Hold an LC modifier and press a step to write the corresponding status; with no modifier a press toggles OFF ↔ ON.

Shortcuts

Step editing (LP columns 1–8, LHS + RHS)

Gesture	Where	Action	Modifiers
Press	LP grid	Toggle `OFF` ↔ `ON` (`TRIGMUTE` → `ON`; sustain steps break first)	none
SHIFT + press	LP grid	Toggle `PERCENTAGE_CHANCE` (chance level set per-sequencer via LC knob)	shift
MUTE + press	LP grid	Toggle `TRIGMUTE` (force-silence the step)	mute
SOLO + press, twice	LP grid	Sustain region: first press = start, second press = end (wraps across bar end)	solo
REC ARM + press	LP grid	Cycle mod division: `OFF` → `MOD1` → `MOD2` → `MOD4` → `MOD8` → `MOD16` → `OFF`	rec_arm
8A + press	LP grid	Inverse mod: → `INVMOD4` (`MOD8` → `INVMOD8`, `MOD16` → `INVMOD16`); press again converts back to `MOD`	8a
8B + press	LP grid	Euclidean overlay: pressed step = rotation point; same step again toggles the row’s Euclidean off	8b
SHIFT + MUTE + press	LP grid	Reset row: all 16 steps → `OFF`, Euclidean pattern cleared	shift+mute
SHIFT + SOLO + press	LP grid	Randomise row: random-density trig fill	shift+solo

Row mute buttons (LP column 9, LHS only)

Gesture	Where	Action	Modifiers
Press	Row mutes	Instant toggle row `MUTED` ↔ `UNMUTED`	none
SHIFT + press	Row mutes	Row autodrop cue (muted row comes in / active row drops out, auto-reverts)	shift
MUTE + press	Row mutes	Toggle `DRONE` mode	mute
SOLO + press	Row mutes	Toggle `LEGATO` mode	solo
REC ARM + press	Row mutes	Cue mute/unmute transition at next bar 0	rec_arm
MUTE + REC ARM + press	Row mutes	Cue `DRONE` at next bar 0	mute+rec_arm
SOLO + REC ARM + press	Row mutes	Cue `LEGATO` at next bar 0	solo+rec_arm

Euclidean fader controls (LC faders, while in trig view)

How to add a Euclidean to a row. Hold 8B and press any step on the target row in the LP grid. That step becomes the row’s rotation point (the pattern’s starting step) and the row picks up a default Euclidean pattern. Then use the three faders below to set density, rotation, and length. To remove the Euclidean from a row, hold 8B and press the same starting step again.

Control	P1 / P2 fader	Action	Modifiers
Density	6 / 14	Pulses in the selected row’s Euclidean pattern (0–length)	any
Rotation	7 / 15	Pattern start offset (same as 8B step press)	any
Length	8 / 16	Pattern length 1–16 (clamps density/rotation)	any

Special case

Gesture	Where	Action	Modifiers
Press row 1 (bottom row, H)	Row mutes	Boom-TSK toggle: fires a fixed 4-on-the-floor BD (steps 1/5/9/13) + off-beat CH (steps 3/7/11/15) pattern on TR-8; immediately mutes every other row of sequencer 13 (main and alt) and force-unmutes the sequencer. Pressing again clears the patterns and re-mutes row 1.	none
