Handbook — per-step editor.

Note detail

Per-step velocity, probability, lane volume, and conditional ratchets — opened by a long press on encoder 4 on top of an existing note.

Opening the editor

Place a note in draw or single mode, then long-press encoder 4 on top of it. The matrix swaps from the grid to a dedicated layout: four vertical "value bars" with a small text label between them. The note keeps playing whenever the playhead reaches it — you can hear changes live.

What you see

A red-orange ramp on the left, a five-stop probability ladder, a blue-cyan lane-volume ramp, and a small fraction (e.g. "1/2") on the right.

What to do

Turn each encoder to slide its corresponding value. Long-press encoder 1 to exit back to the grid; the changes are already saved.

What changes

The single step you opened — not the whole row. To edit several steps at once, repeat the gesture on each.

The four columns

Example layout: medium velocity, mid chance, high lane volume, "1/2" conditional fraction.

1 Encoder 1
TurnHit velocity / impactScales how hard the voice is driven through amp + filter. Maps to MIDI 1–127 under the hood.
Long pressExit to gridReturns to the previous draw or single view.
2 Encoder 2
TurnProbability ladderFive stops: 0% · 25% · 50% · 75% · 100%. Lower values randomly skip the step during playback to thin busy patterns.
3 Encoder 3
TurnLane volume trimBiases this step's instrument level vs others without opening the mixer.

TurnCondition / ratchetFractional repeats shown as miniature text. Creates syncopated or every-n-bar hits inside the same grid cell.

Condition triggers explained

The condition column is the most powerful and least obvious feature on the screen. Each setting is a fraction the firmware reads as "this step fires every n-th time the pattern reaches it":

FractionEffectUse it for
1/1Always firesThe default — same as a plain note.
1/2Fires every other pass through the pageTwo-bar variations without painting two pages.
1/4, 1/8, 1/XSparser — 1 in 4 / 8 / randomRare accents and "every fourth fill" hats.
2/1, 4/1, 8/1Ratchets: 2 / 4 / 8 quick repeats inside one stepDrum rolls, glitches, machine-gun hats.
X/1Random ratchet countLo-fi humanisation.

Conditions combine with probability: a step set to 50% with a 1/4 condition fires only when both checks succeed — extremely rare, used sparingly.

Practical tips

  • Velocity follows envelope shape. If your sound has a long attack, low velocity may not "land" before the next step. Pair velocity with the attack stage in Sound → ADSR.
  • Probability is also a thinning tool. Set every hi-hat step to 75% and the loop instantly stops sounding like a machine.
  • Ratchets are loud. A 4/1 condition plays the same sample four times inside one step — drop velocity or lane volume to compensate.
  • The screen only edits one step. If you want every step on a row to share a velocity, use the velocity encoder live during playback (in single mode + PLAY → CTRL = VOL) instead.
