Hoisel,
Shut down your Mac.
Unplug any and all midi keyboards and controllers
Make sure you have quit (and not just closed) any and all Midi related apps on your iPad.

Restart Mac
Now delete both the preference files using these instructions.
To delete the user preferences, do the following:
You can resolve many issues by restoring Logic Pro X back to its original settings. This will not impact your media files. To reset your Logic Pro X user preference settings to their original state, do the following:
- Quit Logic Pro X
- In the Finder, choose Go to Folder from the Go menu.
- Type ~/Library/Preferences in the "Go to the folder" field.
- Press the Go button.
- Remove the com.apple.logic10.plist file from the Preferences folder. Note that if you have programmed any custom key commands, this will reset them to the defaults. You may wish to export your custom key command as a preset before performing this step. See the Logic Pro X User Manual for details on how to do this.
- If you are having trouble with a control surface in Logic Pro X, then you may also wish to delete the com.apple.logic.pro.cs file from the preferences folder.
- Restart the computer.
Note: If you cannot find any of the files listed above, you didn’t follow the instruction correctly! 🙂
Test without plugging any midi keyboards or controllers into your Mac..
Create a New project...... and just use LR itself and see if that fixes things.
Do not test with an existing project just yet...
If it now works correctly, load up an existing project and see if that still works...
If it does, plug in each one of your midi keyboards and controllers, one at a time and test after each one...
Fingers crossed that should resolve your problem or help identify the cause of this issue....
