I welcome advice on the best way to use the Genesys XP to seamlessly perform a medley consisting of several different styles and tempos and associated differing sound presets. For example, I wish to perform the Godfather songbook in one performance, going from ballads to mazurkas to tarantellas, etc... Is there any way to use style variations and foot pedals or whatever to do something like this instead of being locked into creating a midifile and playing along with the midifile? I use the XP with a digital accordion. Maybe I'm wishing for too much, but it doesn't hurt to ask others much more experienced than me.
