Fran, Bill, others how do you use the Audio keys on gigs or?....
seems like a really interesting usable feature..

And another thing even though discontinued why can't I find any units for sale anywhere, ebay etc,?...
people just won't let go of them that says something..

hoestly with all the other parameters you can adjust on the BK9 I never got around to using the Audio Keys. I'm just now going over some editied Styles and programming the OT settings. I really like that feature as it gives you 4 instant setups for a Style. Since I don't do a Preformance for each song but use a Style for a number of songs it gives me a lot of flexibility.
Your right people just don't want to give them up, don't know why Roland dropped it.
