I'm starting this thread as a collection point for people to post them if they feel like making one, or a few.
I've made one for the Sony Oxford Transmod as an example and have attached it below.
To make a CSParameterOrder.plist file for a plug-in:
1. First go to HD/Application Support/Logic/PlugIn Settings/ and within almost any of the individual plug-in folders you will find one of these files. Copy one of them to the desktop. Clip Distortion is a simple one to use.
2. Open the file on your desktop with Text Editor. (If anyone knows a better editor to work with these files, let me know!)
(Some candidates in the following posts!)
3. Each parameter has a number assigned to it permanently. The name is only for your reference when working with this file, ie changing the name here doesn't change the name that appears on your control surface display. So change the names as you like to match the new plug-ins parameter names. Or you don't need the names at all. They are just for convenience.
4. The order they show up on your control surface is determined by where they are in the list. So in this example, if I wanted Overshoot and Rise Time to be last, I'd place them at the bottom of the list, like this:
<string>6 Rise Time</string>
5. If you didn't want one or more parameters to show up at all on your control surface, just delete that line for that parameter number. (This is the coolest feature, as some plugs include stuff you'd usually not need on a control surface.)
6. When you're done editing the order or removing parameters, select Save in Text Edit.
7. Place this file in the user preset folder for the plug-in. So, for the attached Transmod example (if you had that plug) you would place it like this:
[User Folder]/Library/Audio/Presets/Sonnox (AU Native)/Oxford Transmod/CSParameterOrder.plist
That's all there is to it. If you make one, put it in a folder named after the plug-in, zip the folder and then attach it. Because they will all have the same filename this avoids confusion.
Here's what my attached Transmod file looks like:
