Actually, you shouldn't have to touch the controls to get the effect of the solo harmony voices. The 9000, 740, and 8000 automatically set the Squeeky Mouse and Karaoke girl to the correct setting--no lead voice. It is a boo-boo that the 2000 does not.

I'll be "On The Road Again" for two days. See ya'll later.
