All our products that were released with the capability of Software upgrades were initially released with OS-1.0. Gradually, these updates went up as high as 4.0 (with some releases having a, b and c updates for minor changes); so "... based upon the upgrade history of Ketron Products...", we have offered upgrades on previous products (and I mean the true history now).

With the Midijay also being software upgradeable and the current release being at 1.0, a couple of more upgrades are well anticipated into the future!

Thanks,

AJ
