Scale Lock

Scale Lock snaps every note in the selected MIDI clip to the scale currently set in Live (read from the Set, not guessed), with a choice of snap up, snap down, or nearest. It reports how many notes were off-scale.

It reads the root note and scale intervals from your Set, snaps each note’s pitch into the scale, and writes the notes back. It moves pitch only, never timing. The edit is one undo.

Right-click a MIDI clip (or a clip slot selection), then Lock to Scale…. A small dialog shows the live scale read from the Set (for example, “Scale: F Minor”), three options (Snap up, Snap down, Nearest, with Nearest the default), and a count line like “7 of 32 notes are off-scale”. Press Apply.

Scale Lock reads the scale you set in Live (root note plus scale intervals) and snaps notes to it. It does not invent a key: if no scale is set in the Set, it has nothing to snap to. It moves note pitch only, never timing. Microtonal and tuning-system scales are out of reach in this beta (the SDK exposes scale intervals as semitone offsets and no tuning-system access). It is user-invoked, never auto-triggered.
