Give the reverb a starting point
These are rhythmic examples, not room models or guaranteed settings. Try a value, then adjust it to the sound, arrangement and effect you are using.

Use the numbers, trust your ears
Delay follows the repeat
The calculator gives the interval between repeats. A quarter note at 120 BPM is 500 ms. Dotted gives 750 ms; a quarter-note triplet gives 333.33 ms. Feedback controls how long the echoes continue, so it is a separate setting.
Pre-delay leaves a gap
Pre-delay is the time before the reverb begins. Short values can help separate the original sound from its tail. A tempo-related value is a starting point; a precise rhythmic match is not always the best-sounding choice.
Decay is the tail
Reverb decay describes how long the tail fades. The examples above express a musical duration, but plugins may define decay differently. Balance the tail with the arrangement and listen for masking rather than relying on a room label.

Using your timing results
Check your tapped BPM
Follow one beat rather than every percussion sound. The last eight intervals are averaged; the variation describes your tapping. It does not prove the track has that exact tempo. A pause of five seconds starts a new sequence.
Use it for a quick check of vinyl, a live performance or music playing outside your DJ software. For style exploration, visit the DJ Genre Guide; genre alone does not determine a track’s tempo.
Check half and double time
A 70 BPM count can describe the same underlying music as 140 BPM at another beat level. Compare with the phrasing and your DJ software before using a number as the track tempo.
Prepare the next transition
Use phrase length for musical duration and the DJ Set Planner for whole-slot track counts. These tools do not locate a track’s downbeat or arrange a playlist.
