A little investigation showed that I was running JBridge 82d. The latest, Mavericks compatible version turns out to be 89c. Ten minutes later I had it loaded, rebooted and problem solved. Not going to wonder why this wasn't an issue in DP 8.06.
Which leads to my question: Is anyone using the mda plugins successfully in DP 8 64bit? I am betting no but, if anyone is, I'd like to know the secret. The bridged VSTs load and I can hear them but cannot see their GUIs to adjust them. In DP 8 32bit, the VST GUIs don't appear - only those for the AUs.
I know the workaround: Open these projects in DP 7 or 8 32bit and use the AUs.
I also know the solution: Replace those 32bit AUs with 64bit plugs that do the same thing (I can't think of any that are critical; it's just the time involved, ya know?). This is in case Apple drops support for 32bit audio.
I haven't used mda in a new project in years but still...
