Bad Snacks demonstrates how to use Ableton's Transform Quantize to fix imperfect MIDI timing after recording. With all notes selected via Command A, the shortcut Command Shift U opens the quantize window, where snapping to a 16th-note grid locks everything into place instantly.
This is one of the most common post-recording cleanup steps in any MIDI-based workflow, and the 16th-note grid works well for chord parts where rhythmic precision matters more than feel.
