Mario-I'd be interested in what you find out. I still play 2 old MS-60's. For some reason, I believe the MS-100 was later than the MS-50 but before the SD-1 and the like.

Recently got an SD-5, but have not begun playing it regularly. Also have a Midjay...same deal...not using it on a regular basis, but will soon.


Let me know what you think. I really like Ketron (Solton) stuff!
