Microtiming and Groove
Notes need not sit on exact grid lines; a few milliseconds of push and pull decide how a groove feels.

The problem
Quantise a drum kit fully to the grid and it sounds clean but has no push; leave the take untouched and it may fall apart. The difference often lies in a few milliseconds: a snare slightly late, a hi-hat slightly early, the way bass locks with kick. That is what makes a groove drive or drag.
How it works
The ear resolves timing differences in the millisecond range, so a tiny offset changes how a groove feels. Swing pushes the second eighth of each pair later, anywhere from even to triplet feel. Instruments relate to time differently: in a kit the kick usually sits on the beat, the snare a touch behind and the hi-hat a touch ahead; bass locks to kick while guitar strums may lead. Quantisation erases offsets, and with them the style.
Settings and practice
Keep the original take and quantise selectively, fixing obvious errors while preserving deliberate offsets. Choose a swing ratio that fits rather than applying triplets everywhere. On drums, quantise only the kick and leave the snare and hats alone. Align bass to kick but keep a small difference for weight. Copy microtiming along with duplicated sections. Over-alignment kills the human feel, while over-preservation makes sections fail to connect.
What to listen for
On the funk kit, the push from a slightly late snare; on the hip-hop kit, the sway from kick against sliced samples; on the gypsy tune, the snap of ornaments landing early. The difference is not in the notes but in the moment they land.
