This walkthrough of Ableton Live 12's Pitch and Time Utilities tab shows how to reshape freehand-drawn MIDI notes without breaking your key. With Scale Mode engaged, Fit to Scale nudges sloppy notes into the nearest scale tones, turning a rough sketch into something usable instantly.
Invert flips a phrase on its vertical axis while staying locked to the scale, giving you a quick way to generate a new melodic idea from an existing one rather than starting from scratch. Both tools behave differently depending on selection: with nothing selected, the transformation hits every note in the clip, but selecting specific notes limits the effect to just those.
Add Interval stacks a new note above each existing one at a set distance, and because Scale Mode is active, that distance is measured in scale degrees rather than semitones. Clicking it repeatedly keeps layering notes at the same interval, which is a fast way to build full chords out of a single melodic line.
