I just bought a used JV1010 and realized I didn't get the sample version of Sound-diver that comes with it. I too want to save performances. Anyone know where to get that copy?

First - contact the place you bought it from, see if they have it.
Second - If they haven't got it, try and contact Roland, they might send you the disk.
Third - Roland may well tell you to contact emagic, who make SoundDiver.

I think Roland is your best bet...
