The box has a lot of nice features and functions but wouldn't it be hard for a solo performer to control 'live' on stage? It's nice that most things seem to have a dedicated button, slider, etc., but that seems like an awful lot for 'older' performers to remember, especially since they can't even seem to remember to hit a 'fill' button once in awhile on their arrangers . Seems to me most of those controls are intended for 'live', on-the-fly control. I guess you could pre-program a lot of it but doesn't that defeat the whole purpose of the machine? Don't know about the rest of you but I have to re-learn how to use my smartphone every day (I can now sucessfully answer 1 out of every 3 calls---where's my damn flip phone).

Love the technology but don't know if I'd want to sit through two solid hours of vocals. But that's just me.
