I wish I could afford them all!!!!! I'm sure I will like Tyros 5 regardless of how they make the styles. All my progressions from Tyros 2 to 3 to 4 have been positive. Regarding loops.......I suspect that any arranger wouldn't have the fast processing power of a PC. I treat playing music differently playing Tyros 4 versus playing a midi controller on a computer. When I play Tyros 4 I am performing............when I use the PC I am composing, mixing and recording. I like switching between the 2 to keep me from getting bored.
