Hi Joshua
Since you've already established that it's not a template issue, and your system specs look like they should be able to handle just about anything Sib related, let's see if we can narrow it down. Remove your Sibelius Player instance, add another instance of Kontakt Player and assign the VDL template sound set (the S7S staves should load a piano or something). Does it still behave the same?
Try posting your Playback Configuration again, it didn't get attached for some reason.
Also, you can send me the file(s) if you'd like me to take a look at them on my machine. Sent you a PM.
