Since Many if you have asked, here is a step-by-step guide to notating Organ Music. I hope you find this Interesting.
Step 1: Notate your peice's TUNE on my (unregistered, as i was when i made it) manuscript: http://rapture.squiggle.org/~david/junk/NWC/ORGMAN.NWC
Step 2: Add two more staffs, mute them, and notate your peice as proper organ sheet music. (with a font for special characters)
Step 3: Insert a pitch bend of -5 on each staff, exept the two you have just inserted.
Step 4: Hide all the staffs with the tune on.
Step 5: Enjoy Listening to your Fine Organ Composition!
Oh, and I apoligise if this is wrong. This is probably because I Don't Play the organ.
