Mbo, there used to be a great little shareware package known as HARPING which allows you to take any MIDI file and display where you need to blow and draw for each note. You can select a diatonic harmonica in a different key and it will show you the different playing pattern (and how feasible it is to play in that key). It has loads of other great features and the shareware version was full featured.

It used to be on ZDNet and other shareware sites, but I couldn't locate it in a quick search this morning. Maybe someone else can find it, otherwise send me a PM and I'll see if I cand find my original download.

Regards, John

One of the Demo songs is Love Me Do - right up your alley.
