I use note worthy too, But what I want to do is make a midi so I can sample Our songs on my site.
I want to write out the sheet music, save it as midi, up load to website, play on web site,
Any way I figured out what to do, my web site is: http://www.geocities.com/hanzaki_mishima/index.html
The music isn't up yet.
