For some reason my Marching Machine is playing back a bongo sound. I've tried creating an instrument change, creating a new staff specifically for the instrument and the problem remains. However when I load my template and create an instrument there the machine plays back correctly. So I'm guessing the problem lies within my current sib file. I have also tried other instrument changes and they seem to be working fine, so my (humble) guess is that it's not a ";too many instruments loaded"; kind of error.

Where should I be looking to figure out why the incorrect sound is being triggered?

Forgive me if this has been asked before, I didn't see it show up in any searches and we can only imagine how many times the words ";marching"; and ";machine"; are used here.

Brent,

My guess is that it's possible the marching machine ";instrument"; in the sibelius file you're having problems with may have gone wonky in its mapping. This can sometimes happen for odd reasons, but luckily it's not too common.

There's a discussion on how to troubleshoot it here:

Let us know if that has anything to do with the problem you're seeing.

Thank you Jim and Bryan! The fix found here (http://www.visaudiodesigns.com/media/videos/gongfix.mov) was exactly the issue.

Everything is running smoothly now, pun intended.
