I want to share my opinion on my first workstation that I had to use for ten years I make music but I've had it about 3 years in hand.
for characteristics, see sheet roland xa.
I like his touch and in addition it features 128-voice polyphony, it's the bomb.
There are good are like us used roland but I would say frankly that there are good: piano (roland c), but the guitar layers are for me too just and sound for a unitization musicians.
but having programmed with the studio, I said to all the people I handed out prog heard sounds good.

UTILIZATION

Easy to use no manual for me, it is so clear
The sampler is easy enough but I do not like to edit sounds

SOUNDS

Sounds right for me but the tablecloths are not overloaded sometimes playing live solo, I cry my old korg n5ex.
But ls pianos, huwa! but happiness
The velocity is good and a good very good aftertouch
The acoustic guitars to try.

OVERALL OPINION

I have 3 years but I have to go on separate korg tr I'll write a review very prochenement.
with test pattern, I can not make the mistake of comparing it to what I call pattern 6ES (development system), but it approaches the sound characteristics (personal).
I bought it but with a rack for the ground since I also play live.
