Hey Spike, I know what you are talking about. I too sometimes cheat and transpose my keyboard. On most songs, I play in whaterver key the singer wants, but on some chord intensive songs like "Crazy" I may have to transpose, if the singer wants some other key than C. But then when there is a modulation to another key, I'm in trouble. I have to stop playing long enough to set another traspose value.

An amusing anecdote: I was playing in the house band for an open mic talent show when a singer comes on stage and announces she wants to sing "Crazy" in the key of B flat. No problem, I transposed my keyboard. The bass player was lost so he stepped behind me to watch my hands. Then he was really lost. I was playing the notes for C, but the song was in B flat.

I would like to be able to get rid of the transpose crutch, but I'm not there yet.
