msutliff,
I only use the LT SMF songs as backup to my KB,....Only once I forgot my KB at home and had to use the LT solo to get thru the gig which worked flawlessly. It was like doing a Karaoke job, Singing thru the PA to SMF, Mp3's, and custom backing tracks, plus all my lyrics if needed are on the LT also. It works great and is a fantastic backup without haveing to carry extra Kb's.
As far as the Sound card....I have the Roland Sound canvas SC88h wave table installed on the LT this provides a great sound just like your KB would when playing SMF songs. The LT is a Must for todays giging arranger KB musician to fill the needs of so many different venues
