After some checking, the Save/Restore issue is no longer present in the
latest version of Logic - the settings are saved and restored whether
or not a parameter is exposed. Nothing has been changed in our code
that should effect this, so I think this issue must have been resolved
in Logic. By the way, settings are saved/restored in AudioUnitHosting
whether or not a parameter is exposed.
The Factory Preset issue still exists. Logic checks for parameters
first. If I do not expose a parameter, GetPresets is never called (a
GetProperty call is never made for the assoc prop) and the preset menu
is not displayed in Logic. If I expose parameters GetPresets is called
and the presets menu is displayed. I think this may just be a Logic
issue. I don't see anything in the base classes that should cause this
behavior.
Automation is not really within the scope of two of our plug-ins. Our
other plug-in would definitely benefit from parameter automation
however, the addition of this feature was delayed for a few reasons
(but not at all because we felt it wasn't valuable).
Thanks!

Is it a requirement that every AU expose parameters (for automation
through the host, etc.)? Our plug-ins do not currently expose any
parameters. With no parameters exposed in Logic, our settings are not
saved/restored and our factory presets are not used. If we expose a
dummy parameter, everything works as expected. Is there some reason
for
this limitation? Based on the SDK, I do not see any reason for these
areas to be linked in this way. Am I missing something?
