Another surprise I found was Yamaha's reply to Korgs dual song player. In the Korg, you can load either smf or MP3 in either player, but the Yamaha only lets you transition from one format to the other. This is because they have different players, I suppose. The fadar is slower, and digital, but it does give you the opportunity to cue up an SMF and an MP3 and fade from one into another. Nice surprise.
