Re: percussion clef and change clef commands

[Donald J. Stewart]

1 - I copied ALL of the notes/etc from AFTER the time signature
2 - I deleted the entire staff
3 - I added a new staff -- it seems the initial staff was already set to 'bass'

This seemed to fix the first set of pitch issues (before the clef change)

I've attached screenshots of denemo scores and corresponding print scores with 
the bass clef and the percussion clef invoked. You'll see how the print score 
moves the pitches.

It seems that when I try to change the clef within the piece itself, it tries 
to use the viola C-clef pitches in the print.

The percussion part changes between pitched and unpitched instruments, which 
is why I'd like to change clefs in the staff.
