Thank you, Nigel!
John, as for backing tracks, they make me feel less free. Actually, I don’t even use registrations much, it’s something about predetermination which bothers me.
You know better than me that when it comes to amplifying the sound of a classical guitar it’s hard to preserve its natural sound. A nylon guitar on PSR is monotonous comparing to a real one, but in many cases it sounds more authentic than piezo pickups. But maybe I need to study this subject more closely.
