Today the German audio software and hardware manufacturer Steinberg announced new driver updates for two of its long dead hardware MIDI interfaces, the Midex 3 and the Midex 8. Even though these products are still officially discontinued and no longer supported, the new driver updates make them compatible with current Mac and Windows
operating systems (Windows Vista, Windows 7, Apple's Leopard, Snow Leopard, and even the bleeding-edge OS X 10.7 Lion).
This is certainly a thoughtful gesture from Steinberg. It's always a big plus when a manufacturer makes its products future proof, even in an unofficial capacity. Steinberg still manufactures a complete line of audio interfaces and DAW software. Investing in one of its products today should keep you covered for several years (and operating systems) to come.
