You are writing in the "feature request" department, this is a little bit confusing. You should ask your question under "StudioLive Mixers/Classic Mixers". And - please - be more precise: Which mixer? Any computer/firewire connected? Are you using remote control (iPad)? Which firmware version is installed?
The "StudioLive Mixers/Classic Mixers"-area is a good place to look for answers, the forums are even more helpful (http://www.forums.presonus.com).
It is NOT a change of the sample rate or a scene, that helps some of the original boards to get working. It is the firewire ID number, that needs to be switched from 0 to 1 and back to 0.
