I have a Yamaha PSR 500 61 key keyboard with a MIDI input/output capability. A friend is letting me borrow his J880 which he never used and has no manual for. I'm just interested in using the keyboard on my Yamaha to access the sounds from the 880 through an amp -- no plans to compose/etc. I'd appreciate it if someone could just give me the basics of how to do this. I'm pretty computer literate but am just learning the jargon of synths. Thanks.
