i have about 10 keyboards but as arrangers go, i have:

Roland G-70
Ketron XD-3
Ketron Audya 4
Ketron Audya 5

maybe i should have bought the PA3X or T4 instead of another Audya? nah !!

What is the point of having 2 same arrangers?

cuz you could sound twice as good, lol

well you could have 1 as backup, BUT

i'm thinking of selling my Audya 4,
as my XD-3 would serve me well as backup

Mirza...Audya 4 is a module - audya 5 is a keyboard

I know ...But I think it's a waste to have two of the same keyboards.It doesn't matter which ones.
I think if Ketron brings MOTL with Aydia styles and sounds it's going to be huge winner.

If you want a functional backup, you need something that can play your styles and performances from your main keyboard... otherwise, it isn't really a backup, it's a replacement!
