Guide

Tap tempo, explained

Tap along with the beat to count the BPM, then read off delay times for quarter, eighth, dotted and triplet notes.

Counting the tempo

Tap the big button, or press the space bar or any letter key, on every beat. After three taps the tempo appears and gets steadier the longer you tap; the last 16 taps are averaged so one early or late tap barely moves it. Pause for two seconds to start over.

Delay and reverb times

Delays and reverb pre-delay sound tight when they match the song. One beat lasts 60,000 ÷ BPM milliseconds: at 120 BPM a quarter note is 500 ms, a dotted eighth 375 ms and an eighth-note triplet about 167 ms. Type a tempo to get the table without tapping.
