Well, I play an FR-7 that I picked up in February. I compared the Orla XM900 (their newest) with the Ketron XD3 and SD3 modules. I believe the Orla is simplier to use, but after listening to samples of both the Ketron and Orla, I decided that the Ketron voices and accompaniments were superior, more realistic. The Ketron has a lot of features you may or may not ever use. NOW, I pick up a MIDI cable tomorrow, and will try the SD3 I bought and hopefully, it will connect no problem. The XD3 and SD3 come up in "Accordion Mode" and the hookup should be fairly smooth... wish me luck!
