If you sequence with Cakewalk Sonar and your fav keyboard, the instrument definitions list allows you to type in say "ba" and see all instruments starting with those letters (to audition bass sounds for this example). While the song plays, you can try out many different basses and select the best for the song. You can can do this with organs, strings, saxes, guitars, flutes, trumpets, drum kits etc. or "live"/"sweet" voices on Yamaha keyboards. I use more sounds than I can keep count of this way.
