Hi Zuki!
Well it's serving the purpose. It is not a Roland, but with some tweaking it might get there. For the coupple gigs that I had, I used a set from a friend and it was OK. Right now I am tweaking the sounds and figuring out the style structure ( much more complicated approach than Roland, but similar). The manual isn't very helpfull, so you can imagine what I'm going through.
Overall, it is a very powerful board with a lot of possibilities.
I also heard that there is a new OS - update coming up with some major improvements. So, I am waiting to see what the update brings.
How far along are you with yours?
