To be more specific the "Toggle Zone Mute" buttons do not illuminate on my APC40, although the buttons themselves still function properly in that they do mute the zones and I can toggle them. It's strange though because it all works fine when I use Beyond 2.1 but the lights stop working when I load 3.0. I'm using the same workspace that I created in 2.1 and loaded into 3.0 and it's the same midi map. I suppose it's not that big of a deal but it is kind of annoying not having the indicator at my fingertips. I have to keep checking the preview window to see which zones are muted and then make sure I press the right buttons to unmute them. If anyone has any suggestions I'm all ears. I've tried reloading the template as well as looked for the configuration settings for the mute buttons but I must have missed them.
