Just some more things you need to know:
1. I expect that you can open the file in a full-fledged copy of Finale, even though the file was created in Finale Notepad 2006, though I don't know what kind of quality you're going to get out of it. Double check the downloaded copy against the .pdf when you get a chance, just to make sure everything copied over correctly.
2. Those little tildas through the notes on the snare part are diddle marks - it means to double-stroke the sixteenth notes. An actual diddle mark is a diagonal slash like this ( / ) at the same location on the note as the tilda. Give your copy of Finale a good looking-through to make sure there is nothing closer to a correct notation before going ahead with the notation I used. If there is anything unclear about this particular point, make sure to PM me before you finalize it.
3. The two notes on certain measures on the Cymbals staff are, of course, split parts. That means that half the cymbal line plays the entire first note, and half the line plays only the second note. I'm sure they'll understand this. To write it in Finale, though, you will have to use a different staff color, presumably, in order for it to show up on the same staff.
4. Of course, given the chance that you yourself do not know, the drumline will know what to add in at measures 34-35, since they play that little ditty all the time, I imagine. Ignore the notes written there - they are just placeholders.
5. I trust that Finale has Marching Band midi packs. If they do, they will have preset Bass Drum, Toms, and Cymbals midis and staffs. Use those, if available. If not, just copy the look of the ones I have prepared and change the staff name. It's what I had to do. (/sighs)
6. The midis on the downloaded copy, I expect, will be all screwed up. That is because in Finale NotePad one cannot adjust the percussive sounds to make a staff just the way one wants. However, in Finale, I'm pretty sure that you can. Take advantage of this, especially when recording the final result, so I can hear, for the first time, what it sounds like. I'm sure you understand how much I would appreciate that.
I think that's about it for now. I leave the rest in your capable hands.
