Bad Snacks records a live bassline with a MIDI controller, then uses quantization to fix the timing. The take runs a little late, so she selects all notes with Command + A and quantizes to eighth notes using Command + Shift + U, snapping everything into place.
The before-and-after is immediate: a loose, slightly dragging performance becomes a tight, locked-in bassline in seconds. Eighth-note quantization works well here because the bassline is rhythmically simple, and the grid aligns naturally with the intended feel.
