Last night I had a request for "Autumn Leaves".
I used to play it from a fake book, but I haven't carried those in years. I didn't have lyrics and really didn't remember the chord changes. However since a rather large tip was attached, I ran a quick search on my laptop, where several thousand midi files reside.
Sure enough, it popped up. I transferred it to thumb drive, popped it in the Tyros 2, and held my breath, hoping it had the lyrics imbedded and hoping it was in the right key.
Sure enough it worked! I quickly muted the melody on track 4 and sang the heck out of it. Everybody thought I knew what I was doing!
