Great sounds on it AMAZING in fACT.
imo it CAN be used for professional work IF ya have a computer to transfer the sounds into I.E logic or cubase and ya can master the sounds to releaseable quality.
Part of my kit is a Yahama rs7000.
Its the RMX's big bro, has a few more things on it and good sounds but its not realy doing the job.
It does have the possibilys of doing the job I just find recording notes on it an absolute BITCH :lol:
Other than thats its good m8 and a worthwhile purchase.
