BPM counts the bottom number of the time signature: quarter notes in 4/4, eighth notes in 6/8. Count-in lasts one measure. With triplets enabled, each quarter-note beat uses the best-fitting straight or triplet grid across your takes.

Ready. Start recording to hear the count-in.

Keep tapping as the recording loops. Press Enter during the next take when you are done: the take in progress is always discarded. Record at least one full take first. Each grid position needs taps in more than half of the completed takes; silent takes count too. Held keys do not repeat taps.
