The XP-30 is basically a JV-1080 with 61 keys and 3 built in SR-JV-80 expansion cards. Orchestra, Session, and Techno. The keybed also has velocity and aftertouch. This particular example is in very nice condition. I’ve gone through and cleaned it and given it a full test. I found all functions to be acceptable and working. I’m a keyboardist, so I know what to look for.
