Key & Scale

Lock playing and editing to a musical key and scale, with in-scale notes highlighted.

Skene can constrain everything you play and edit to a chosen key and scale — a fast way to stay in tune across the whole project, on the piano roll, the on-screen controllers, and hardware MIDI input alike.

This is an important feature that doesn’t appear in the current screenshots; images will be added.

Choosing a key and scale

Pick a root note (the key) and a scale — major, minor, the modes, or chromatic. The choice applies globally to input and editing.

Scale filtering

A Filter Non-Scale Notes toggle controls how strictly the scale is enforced:

  • On — only in-scale notes are playable; out-of-scale notes are blocked, so you can’t hit a wrong note.
  • Off — every note plays, but out-of-scale notes are dimmed on the keyboard as a visual guide.

In-scale and out-of-scale keys are highlighted differently on the keyboard and piano roll, so the current scale is always visible while you work.

Scale filtering works together with MPE: you can keep full per-note expression while staying locked to a scale.
