Most arranger players are pushed just to handle chords and melody. The ability to slip in additional riffs, and control it on a pedal, is probably going to tax most people. Not to mention that it takes real musical talent to ‘hear’ what might work, not just execute it. Even when making styles, or multi track recordings, this is not something most players do well, far less doing it in real time.
So it is going to be a potentially great feature for better players, but maybe not something typical arranger players need to get too excited about.
