What kind of music do you want to scan, HiHo? Because if it's the kind of music that's apt to be on the net in MIDI form, you can buy a music program which will download the music. Then you can transpose it to anything you want with a few keystrokes and print it.

I use the program Noteworthy Composer, and I paid about $40 for it abt ten years ago.

Oh - it's nice to have a music keyboard, too. I use mine to sound out songs that aren't on the net and to write harmony parts to existing tunes. The keyboard needs a MIDI port.
