If you play a wind instrument that reads in a key other than C, iReal Pro prints every chart in your instrument's key while the backing track keeps playing in concert pitch, just as it would in a band. The setting is global and applies to every song until you change it.

 

On Mac, open Preferences and choose your instrument under General. On Windows, open Settings and choose it under General. The Player menu holds the same list on both, offering C, Bb, Eb, F and G.

 

The chart shows a part label, such as Eb-Part, beside the style whenever an instrument other than C is selected. The key in the player controls is always the concert key, the key a piano or guitar would be playing in.
