Hold a pad, change the music.

Four cards, one button each

Latch, Note Repeat, Octave Shift and Kill are in the Library's Performance section. Drop one on a cable like any effect. Each has an Engage button under its power switch, lit while the card is engaged.

Not engaged, a performance card passes MIDI through untouched: the same messages, in the same order, at the same time. Engaged, it does its one job.

Try it with the mouse first. Press and hold the Engage button to engage while the button is down. Option-click it to keep it on.

Wire a pad to it

Run an action cable from your controller's teal jack to the card. It plugs in low on the card's left edge. Learn a press: a pad, a key, a footswitch, a button that sends a CC, or a program change.

New presses on an Engage cable start as Hold: engaged while your finger is down, released when it comes up. Switch a press to Toggle in the cable's inspector and each press flips the card on or off and leaves it. A program change has no release, so it can only toggle.

A Toggle press is a real edit: it's saved, and Undo takes it back. A Hold is live only and never lands in your undo history, however often you stab the pad.

Engaging happens as the MIDI arrives, so a note you play together with the pad already gets the effect.

Latch keeps the chord

While Latch is engaged, letting go of a key doesn't end its note. Mode decides what the next notes do. Replace: the first note after every key was up ends the held chord and starts a new one. Add: each note joins the held ones, and playing a held note again ends it.

Engage with keys already down and those keys latch too. Let go of the pad and the latched notes end, except keys you're still holding, which sound until you let go of them.

The sustain pedal and everything else pass as played.

Note Repeat rolls the notes

Hold a key while Note Repeat is engaged and it strikes again on the grid: 1/4, 1/8, 1/8T, 1/16, 1/16T or 1/32. Gate sets how long each strike sounds, from 1 to 100 % of the step. The card starts at 1/16 and 50 %.

Your own note is the first strike; the repeats start on the next step. Hold a chord and every key repeats. Velocity is as you played it.

With the transport playing, the strikes sit on the transport's grid and follow its swing. Stopped, they run at the tempo from the moment you engage.

Let go of a key and its repeats stop. Let go of the pad and they all stop at once; the strike sounding ends at its gate, and keys still down stay silent until you play them again.

A different rate or amount per pad

One Engage cable can carry several presses, and each can have its own value. In the cable's inspector, a Note Repeat press gets a Rate menu and an Octave Shift press an Amount slider. Both start at Card's, which plays the card's own setting.

Hold two pads at once and the newest wins.

Octave Shift jumps and comes back

While Octave Shift is engaged, new notes move by Amount: up to 24 semitones up or down, or up to 14 steps of the scale. It starts at +12, one octave up. In Scale steps it follows the patch key, like Transpose.

Held notes decides what happens to keys already down when you engage or let go. Keep leaves them at the pitch they started on. Move ends them and plays them again at the new pitch, at the velocity you played.

A key you let go of always ends the note it started, shifted or not, so nothing hangs when the shift ends with your hand still on the keys.

Kill cuts it for a beat

Kill is a mixer's kill button for MIDI. Engage it and every note it let through on its channels ends at once. New notes are held back until you let go. A held sustain or sostenuto pedal is lifted, so the synth doesn't ring on.

What: Notes stops only notes. Everything also holds back knobs, pitch bend and aftertouch, never clock. Channels: All, or the ones you pick.

On release: Silent plays nothing until your next note. Bring back held keys plays again the keys you're still holding, at their velocity. Pedals still down go back down, and under Everything a knob or bend that moved while killed is sent on, so the synth isn't left out of tune.

On the beat or on the bar

Engage follows the card's Switching, in its inspector: Instantly, Next beat, Next bar, or Default, which follows Settings › Clock. While the transport plays, a press lands on the next beat or bar; the release does too. Stopped, it lands at once.

The Engage button blinks while a press waits. Press again before it lands and the newest wins, so a Hold down and up inside one bar lands as nothing.

A press that lands on the bar lands before that bar's notes: a Kill cuts the downbeat, a Note Repeat strikes on its first step.

No stuck notes

Every way out ends what the card started. Holds let go on a scene switch, on Panic and when you open a project. Switch a card off and it releases first, then passes MIDI through. Delete it and its notes end.

Panic clears every Hold, latched note and repeat. A card you toggled on stays on, as a muted channel stays muted.
