Hi Clif,
Perhaps I was jumping to conclusions to quickly? I am anxious for a confirmation that the high-end Yamaha PSR arranger boards (or other arranger brands) include a "built-in" midi-merge function thus eliminating the need for an external "midi merge box".
Perhaps you and other PSR8000 or PSR9000 owners (Don Mason & Paul Ip?) could check and report back your findings.
