Sibelius 7 Sounds updater
http://www.sibelius.com/helpcenter/updates/sib7_1_3_sounds.html
If you have downloaded and installed the Sibelius 7 Sounds library, you must also download and install an update to Sibelius 7 Sounds. Do not download and install this update unless you have already installed the full Sibelius 7 Sounds package.
If you're not sure whether you need this update, you can run it anyway: it won't do any harm, provided you do have the complete Sibelius 7 Sounds library installed.
This update requires Sibelius 7.1.2 or 7.1.3, so if you haven't yet updated to Sibelius 7.1.3, do so now. If you already updated the sounds when you updated to Sibelius 7.1.2, you don't need to run the update again (but it will do no harm if you do.)
Installing the update
First, quit Sibelius 7 if it is running.
Download the appropriate updater for your operating system:
Windows: Sibelius7SoundsUpdate712.exe (51MB)
Mac: Sibelius7SoundsUpdate712.dmg (64MB)
When the updater has finished downloading, double-click the icon to begin the updating process, and follow the instructions on the screen.

Updates to guitar mutes
Increased volume of "Long snare swirl" in brush drum kit
