Tempo Tools.

The numbers you reach for mid-session: tap tempo, delay times that lock to the beat, reverb pre-delay and decay, bars → time, and how far a sample's pitch moves when you change its speed.

01

Tap tempo — and delay times

Find any song's tempo by tapping along, then get delay times that lock to it — straight, dotted and triplet.

Tap along to a song (or press T). It averages your last 8 taps; pause 2 seconds to start over.

Delay times — click any value to copy it

Set a Delay or Echo to these times (or sync it to the note value) so the repeats land in the groove. Dotted 1/8 is the classic, rolling delay.
02

Reverb & time

Pre-delay and decay times that breathe with the beat, plus how long any number of bars lasts.

Why time your reverb

Pre-delay holds the reverb back for a moment so the dry hit stays clear in front. Then set decay so the tail dies away before the next important hit — the space breathes with the beat instead of smearing it. Shorter for busy, fast parts; longer for pads and sparse moments.

Tempo → pitch — for sampling

For flipping samples: how far the pitch moves when you change a sample's speed.

Speed a sample up or slow it down without warping and the pitch moves with it — like a record. This tells you how far, so you can stay in key (or know which key you've landed in).

In Ableton

Turn Warp off on the clip and Ableton plays it at its own speed. Instead, set the clip's Transpose to the semitone value above with Warp in Re-Pitch mode — tempo and pitch move together, the classic sampled sound.
