I'm confused by your post. You say you want better sound but get no sound from RealBand. I assume your computer has a soundcard. If so, you should be able to get sound from any program. If you are familar with BIAB, try that first maybe loading and playing one of the demos. If that works, RealBand needs to 'point' to the right audio or midi devices.

If you have 64 bit Windows, the default Roland VSC/dxi won't work. Instead you have to load the Coyote 64 bit dxi that comes with BIAB. The sound quality of that is not great but it works. PG also sells the Coyote Forte dxi which will work with 64 bit and sounds (to me) far better than the Roland for most instruments. A 30 day trial is available. Next option would be get a different soft synth or hardware synth such as the Ketron which people here love.

In summary, we probably need more info on your computer specs and what you are trying to do.
