how would i create extra staves with the same instrument in sibelius 3 just as i was able to do so in sibelius 2?

This is in the manual and not really a Virtual Drumline question....

I'll answer any way...From within your score, hit the letter ";I"; and add instruments as needed.

You may also want to access the Sibelius help center for more topics related to Sibelius itself.
