After a lot of experimenting I got the single line staves to work for cymbals and drums.
Well, sort of.
The following problems remain:
I've assigned the velocity x-fade to CC11. But the dynamic marks (p, f, ff etc) don't change the velocity for cymbals and drums, which they do for all other instruments.
I can't make the five-line percussion approach work at all (as explained on page 8 in the Optimizing Sibelius Playback Manual). The notes trigger instruments on other channels, for example the piccolo on channel 1.
I'm using Sibelius 6.2 and the latest versions of Vienna House Style and Special Edition Plus sound sets.
