The response so far has been virtually none-existing!!! One person has shared his registrations with me, only to find that they (SD40) were not compatible with my SD9......(and vice versa or so it seems). It is amazing to learn that with over 460 members on that Ketron FAcebook forum there is no interest whatsoever. Oh well, we'll live.......
N.B. Bachus I seem to know you have the SD90 as well, or not anymore ? No registrations you have made then ?
