Hello Andi,
I'm not clear how to trigger certain sounds in the Percussion group from the Special Edition if using Sibelius. Sibelius has a percussion line named Thundersheet. and a note placed on that triggers one of the sounds for it. But the manual says there are other Thundersheet samples mapped C1-B1. What commands trigger those? I can't see anything on this in the Optimize manual, though I can see instructions for some of the other percussion instruments such as metal chimes.
With thanks.
