How do you change the key of one specific loop using the Key/Transpose in the Inspector? Step by step instructions would be great.
Many thanks.
Here is the step-by-step instruction:
Step 1: Select the MIDI Region and set the Transpose value in the Region Inspector to the left.
Step 2: There is no Step 2 😉

If you are a newbie, then I would recommend to have a look at my Graphically Enhanced Manual "Logic Pro X - How it Works" where I explain everything in great details with lots of easy to understand diagrams and screenshots, including a separate chapter about Apple Loops.
BTW: If you have a proper Apple Loop, then it should automatically adopt to the key of your Project. A transpose is not necessary, unless you want to overwrite a phrase to a specific key.
Hope that helps
