What would those of you with interest in this area recommend for me? I have a couple of MIDI keyboard controllers, one as part of an M-Audio Venom. What I need now are some more sampled sounds--strings, piano, etc. to use with my band. The most important thing is cost, so I'm looking pretty much at vintage stuff. I'm leaning towards a Roland JV-1080, but realize I know almost nothing about this stuff. Any recommendations?
