UTILIZATION

- The general configuration is it simple?
Yes it's pretty simple!

No, it's a point that fishing on the unit, plug the publisher is not at all intuitive (you need a big adjustment period to understand the logic korg)

- The manual is clear and sufficient? ...
...

SOUNDS

- The sounds they are suitable to your style of music?
A rather reserved to the music "unrealistic"

- The effects are they effective and responsive?
Yes but the interface effect is imbitable!

- The expression is good? (Response to velocity, aftertouch to)?
The keyboard is very bad (no relation to my Korg M1, day and night)

- What are the sounds you prefer, you hate? ..
Electro sounds: good!
Piano, brass ... : Null

OVERALL OPINION

- How long have you use it?
2 years, I have to sell

- What is so special that you like most and least?
I wanted a general expander but ultimately it's not what I need (it is too oriented electro sound and not at all realistic). If you make music elec, go ahead, if not go your way.

- How would you rate the quality / price?
The price is interesting but since I moved all info for cheaper (and VST plug-ins included with the suite Sonar 8 PE: Dimension Pro, Rapture ...) and then the korg really do not measure up.

- With experience, you do again this choice? ...
Not
