Synthesia Talk

I've just bought the learning pack and my first midi gave me the option to choose to play left or right hand (or both) and sheetmusic. After that I could choose for melody, rythm and recital.

Another midi though didn't gave me this option and just showed two piano's I could chose from (and sheetmusic on or of) and after that the song starts.

How come that midi doesn't let me use the features of the learning pack?

nm I had to assign hands, one to each piano
