Yes
In <AudioUnit/AudioUnitProperties.h> there are some notes about
migration from plugins and you can use this as a way to have a new AU
deal with the presets from an old AU.
However, I'm not sure that this works in the case where the host finds
both versions of your AUs present. That seems confusing to me.
Why not special case the carbon view publication to host that you know
(by host identifier and version) only do carbon hosting, but otherwise
always just publish the cocoa view (or both even) - AULab handles
seeing both (it just prefers the Cocoa view), so I don't know why this
is a problem for host apps

FWIW some vendors do this (Cocoa loader in a Carbon UI) and it seems

Yep I'm doing the Cocoa in Carbon trick. The difference with my
plugin is that I separated the Carbon and Cocoa UI versions into
different plugins - because I wanted a Cocoa host to always load the
Cocoa version and not the faked Carbon version and it simplified
some 64 bit stuff too. So the presets for one version don't work
for the other - I wondered if there was a way to convert presets or
force an AU to load a preset from another plugin..

Hello,
I recently made the decision to build two versions of an AU. One
with a
Carbon GUI and one with a Cocoa GUI. I know I can make an AU with
both
Carbon and Cocoa capabilities but for certain reasons (
http://lists.apple.com/archives/coreaudio-api//2009/Aug/msg00115.html
) I
didn't do that.
Apart from the GUI the two plugins are identical but because they
are
separate components with different resource IDs etc presets are not
interchangeable. Other than implementing a simple patch manager
inside the
plugin is there any way to convert presets between AUs?
Thanks,
Stephen
