Hi Bruce,

It's been a long time...I hope you're doing well. Try this:
1) Start playing a midi file with a harmony track. (Make sure the lyrics are off).
2) Hit "F1" - GM Part
3) Hit the "page +" button until you reach the harmony track.
4) Hit "F8" Part Mode until it says "Vocalize"
5) Hit the red "start" button once so that the light goes out and the song is now stooped.
6) Hit "save/enter" (You can change the name if you like)
7) Hit "F10" Execute
That should do it. It seems like a lot of steps but once you do it a few times, it's easy.

Please email me if I can help.
Take care Bruce.

Bob
