i didn't know busnoi added bars. shows how much I know. I've got to learn the organ! well there is nt enough time in the day. I also like busoni's comments and i always look at his editions of things when they exist, like mephisto waltz, in the main theme after the repeated note intro he wrote "rustico" and that just solved it all for me. Also i have his goldberg variations, and i've seen both volumes of his WTC, and some stuff was so impressive i just copied it into my own score, since i don't own his edition. Can you still buy his editions?
