Quantize note timing in the Score Editor in GarageBand on Mac
You can quantise, or automatically correct, the timing of notes in the Score Editor. This technique is useful when regions in the track contain the right notes, but are not perfectly in time with the project. When you quantise the timing, items are adjusted to the selected note value.
You can use the Time Quantize controls to quantise complete MIDI regions or quantise selected notes in a MIDI region. Select the Region tab to quantise all the notes in selected MIDI regions using the Time Quantise pop-up menu and strength slider. Select the Notes tab to quantise individual notes using the Time Quantise pop-up menu and Q (Quantise) button.
Time quantisation works non-destructively, for playback only. To recall the original timing, set the value to off.
In the Score Editor, you can also visually quantise the display of notes (independent of their MIDI time quantisation) using the Grid pop-up menu, to maintain the readability of notes in the Score Editor while preserving more subtle timing differences in the recorded MIDI notes.
