Visible, but Silent, Count-In - 10/18/12 10:08 AM
As an alternative why not have a visible, but silent, count-in at your current tempo? When playing live, there are some gigging situations where the audible click count-in may not be appropriate. I'm thinking perhaps a large lightly-colored overlay on the chord sheet that would flash something like: 1-2, 1-2-3-4 and you're playing. All completely silent.
