Makes no difference to me, Jack, I don't read music, so i have to do it by ear. But it meant I could learn tunes off a CD, and write them out for others to play from because Noteworthy can play it back to make sure I've got it right. And several of the players in the session were clarinet beginners, and couldn't transpose, and they liked it in a key they could read. BTW most of the Manchester Klezmer tunes were written out by Steve Landin using Mozart.
