Pushing drums ahead of the beat drives energy; pulling behind relaxes the feel — set with track/channel delay
Skilled drummers deliberately play very slightly ahead (‘push’) or behind (‘pull’) the metronomic beat to shape the groove: pushing ahead feels driving and urgent, pulling behind feels laid-back. This is programmable by applying a channel/track delay to the whole drum part (e.g. +12ms of Track Delay pulls the drums slightly behind the beat; -30ms pushes them ahead), or by manually shifting selected hits after other edits. Unlike micro-timing humanization, push/pull is a uniform shift of the whole part. The article notes you can generally push further than you can pull before it just starts to sound out of time.
Examples
Ableton Track Delay: +12ms = laid-back pull; -30ms = driving push. Manually nudge the whole part backward/forward for the same effect.
Assessment
You want a driving, urgent drum feel. Describe two DAW methods to get it, and explain why you can push more than you can pull before it sounds like a mistake.
