Cubase - backing tracks

I am using Cubase for putting together my backing tracks with the Sampletank VSTs. However this is cumbersome and is taking me a lot more time than it should. All I want is a reasonable set of sounds that I can play back on the PC, record to MP3 and use live.

Is there any way of getting the sound bank that is on the Roland MC-80 for use with the PC. I used to have one of these and the sound was great. Or just a good solid soundfont bank that I can just use to replace the 4MB on that came with the soundcard (Audigy 2)

thnks,
