Thunder sheet help
Hi. I'm still new to musescore and have been playing around with various instruments trying to figure them out. One percussion instrument I'm having trouble with is called a thunder sheet. No matter what I do it won't let me placing any notes. I want to figure it out because I might want to use it in my next piece.
Can anybody give me a hand on how it works? Or if nobody knows how to work it could you suggest other instruments to simulate thunder?
I'm on a mac pro using Musescore 1.3.
