Automated parameters are not recalled correctly in Logic/GarageBand

[reuk]

This sounds similar to a known bug in Logic Pro where it restores automation data using parameter indices instead of parameter identifiers. There’s more information in this thread:

Adding parameters post launch to a plugin?

We’ve now heard back from Apple on this topic. This is a known limitation of Logic, but not one that is likely to be fixed. We’ll add some sort of workaround to JUCE, but this will need some careful thought to ensure that the parameter system remains intuitive, maintainable, and consistent between plugin formats. I’ll update this thread once we’ve made some progress.

You’d be affected by this bug if you added or removed parameters between versions 1.0 and 1.1, and the new parameters don’t have a higher “version hint” than the old parameters.

Please can you provide the following information:

• Which DAWs exhibit the broken behaviour?
• Have you added or removed parameters between version 1.0 and 1.1?
• If so, are you setting version hints correctly on all parameters? Parameters added in later versions should always have a greater version hint than parameters added in earlier versions.
