I heard demo's of the Ketron arrangers and was very impressed. I know nothing about these keyboards (and the Midjay). A store about 2 hours away has an SD5 prototype and the complete line of Ketrons. I'm going to view them before Friday because the SD5 is going back to the factory. Can any of you give me a quick course on Ketron for Dummies i.e. what shall I focus on, features to look for, etc. I do stage performing with an arranger and do everything spontaneously so I don't want to fumble with changing settings. Also would like to have some unique "gimmicks" like the G-70 has.I really like what I've heard so far with these demo's so I'm looking forward to playing (which one?).
