Programs like Sonar, Cubase, Logic Pro and Digital Performer and the attendant MIDI sound modules have revolutionized music production. While raising production standards they have done little to make performance any easier. Trying to use them on stage is a study in frustration. The features that make them great production tools get in the way and cause them to be difficult to use in a live environment. OnStage Performer picks up where they leave off and allows your stage show to exhibit the same professionalism in performance that you demand in production.
