G'day John,
Trumpet to 'bone:
All up = pos 1 (closed slide)
2nd only = pos 2
1st only = pos 3
1&2 or 3 only = pos 4
2&3 = pos 5
1&3 = pos 6
1,2&3 = pos 7

--=-- My credo: If it's worth doing, it's worth overdoing - just ask my missus, she'll tell ya laugh --=--
You're only paranoid if you're wrong!
