I don't think that is the problem.
Once you have published a parameter ID you really have to keep that ID
- you can't change it as it will break all existing uses of your AU
that are stored in presets and documents.
But, I don't think that is what he is doing, I think he is adding to
the end - appending - or at least that is what i had assumed.
If however, you are adding the parameter ID into the middle of the
list, then you need to change this in the AU and append it
Sorry if I am causing confusion!

Hi Jankoen,
sorry for the late reply, I was out of the office.
I looked into the issue you've reported and I assume that you've
triggered a bug in Logic by inserting the new parameter somewhere in
your exported parameter list instead of appending it at the end.
Due to legacy reasons, Logic relies on the order of parameters when
storing its automation data. Please file a bug report about that.
Thank you,
Stefan

From the sounds of it, what you have done is fine and seems to have
triggered a bug in Logic; adding parameters should be supported by
the hosts as long as the existing parameter IDs are kept the same.
We'll need to wait and see what the Logic guys have to say

Hi
I'm creating a newer version of my Plugin with some new
functionality. This means I did add one extra parameter to the
parameter list. So far so good. All works fine, but now....
When I open an older session (created with a previous version of
my plugin) that contains automation data in Logic, a lot of
automation ramps are mapped to the wrong parameters. All
AudioUnitParameterIDs are the same between the versions, there is
only one parameter new. What is the right way to make sure, when I
add a new parameter to en exisiting audiounit, the automation in
Logic is mapped right ?
thanks,
