Slur Rules and GPO

1. I have taken a look at the GPO_Aria rules file and noticed that there are slur rules for strings (solo and ensemble) but not for any other instrument.
2. Why is the CC# used in GPO_Aria slur rules set to 64 when GPO uses 68 to evoke slurs?
3. Why doesn't a slur still not work when I change CC# used in GPO_Aria slur rules set to 68?
4. In short, is there a bug in the proper use of slurs with GPO instruments in any situation?
Thnx!

P.S. Is a rules file editor coming soon?
