Ableton/Live/UG/19 Recording New Clips/05 Recording Quantized MIDI Notes
- Edit → Record Quantization lines up recorded MIDI notes to a chosen subdivision.
- In the Arrangement, record quantization is its own Undo step, so Undo can remove the quantization and keep the take.
- It can't be changed while recording, except when overdubbing a looping clip, where changes apply at once and can't be undone separately.
- Notes can also be quantized afterwards with Edit → Quantize; see Ableton/Live/UG/10 Editing MIDI.
