7 Manual is clear.
Display is gorgeous and it is very fine to work with.
It can easily respond to any incoming message, including all controllers. 2 MIDI INs, Computer interface are included. In other words, don't be lazy to get satisfied with 127 GM sounds, this box can give enourmous capabilities just tweaking a little bit with editing and choosing the right variation sounds. The reason I am including this is I needed to alter the customer support rating. My unit recently locked up and a call to customer support stated that the likely fix was a factory reset which could only be performed by a Yamaha technician because the reset required taking the machine apart.
