Bernard,

I received the Ketron SD1000 on Saturday. I revised the RealBand ini file with the four new banks on the SD1000, and it worked perfectly in RealBand. Now for the good news....it is an improvement from the SD2, no question. I really like the new piano voices that are available, and they sound terrific with RealBand MIDI Super Track pianos. The unit itself looks like the SD2, just a little nicer design. Ketron makes very nice products. As you know the SD2 is also very good, but the SD1000 is just better. Is it necessary to own? No, but it is an improvement over the SD2. Hope this helps.
