How to handle differing repeats in systems?
First let me say, I'm new to notation, so apologies if I get some of my terminology wrong.
I'm trying to transcribe some (badly!) hand written harp music on to computer, firstly so that I can read it, and secondly so that I can selectively remove harp parts one by one, and therefore practice them myself with some accompaniment.
The three parts in the music, are Harp I, Harp II and Harp III :-)
The song is 16 bars long.
Harp I is written with a simple repeat beginning Bar 3, ending on bar 6, with a DS back to bar 2.
Harp II is written with the same repeat bars, but with a  ending and a  ending to the repeat. First ending is notated on bar 6, which is where Harp I repeat ends.
Harp III is written straight through, no repeats.
How do I get these all on to one document with Muse Score? It seems to me I can't notate the repeat endings like this for one part, and not the other, and the third part has no repeats at all.
For Harp I and Harp II, I could fake it out by notating the ending twice the same way, but that doesn't help me for Harp III.
I'm using MuseScore 1.0 on a Powerbook G4, but I could upgrade to 1.1 if it would help
Hope I've explained myself adequatley. I can put a scan up in my public dropbox if anyone wants to see the original.
Thanks for any assistance anyone can give.
