Ok, let's see; for sure, the BIB Real Tracks can improve just about any tune you come up with, provided that the style used for the composition is supported by one or more of the Real Tracks existing in the packages so far, however, as far as the melody lines or specific written solos, the sound is going to depend on the synth, vst or other sampling software being used. BIB by itself have no sound whatsoever, just general midi "instruments". The last version of BIB comes bundled with Sampletank player and a generous list of sounds that would be an unquestionable improvement over the "windows soft synth" that comes with just about any computer with a sound card.
Experiment and have fu8n!
