In the Mixer, change the sound of the Drums to either Click or Click 2 & 4.
Select the click sound you want for Click 1 & Click 2.
For Click 2 & 4, you will hear only the Click 2 (off-beat) sound (except for Keynote where it will play all clicks.)
Keynote
New in v2025.2
Select "Keynote" in Click 1 to sound the root of the key of the song for the count in (useful for singers to pitch from.)
For example, a song in the key of D, the note D will be heard instead of clicks.
