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,
