I'm new to this board. I am on the wait list for a MkII (#15154), and can't wait. I was reading this thread and was thinking about this very idea when I got to this message.
I have an S2000 Roadster which doesn't have speed-sensitive volume unlike many convertibles. I had heard that the Empeg had a mic input and may eventually have voice command. But if it could be used for "ambient noise-sensing" and auto- adjust the volume, that would be AWESOME! It would be much better than plain speed-sensitive.
Damn, now I'm REALLY jonesing for my number to get called for my MkII! Hopefully, by the time I get mine (probably Sept-Oct, fingers-crossed), beta versions of this feature will be available!
