Logic Pro From A to Z – J is for Junction Tool

Joining up region boundaries is a relatively routine task. And Logic Pro has plenty of nice functions to help with this. The shuffle left and right modes are a great feature to quickly snap start and end boundaries of different regions together. The fade tool and fade parameters in the Inspector help smooth out any rough transitions. But hidden away in Logic Pro’s arsenal of features is the Junction Tool.

The Junction Tool doesn’t have a dedicated tool icon, or a place in any of the menus. If you search for “junction” in the key commands window, you’ll come up empty. But it is there, ready to serve you under the precise conditions you’ll need it in, and hidden from sight the rest of the time.

Just like when editing takes in a take folder, the Junction Tool allows for simultaneously resizing the start and end boundaries of two adjacent regions. They must be butted up against each other (and we all know how painful that can be!) and have material beyond their visible boundaries available for placement in the timeline.

Just place your regular pointer tool cursor precisely over the split between the two regions, about mid way between the top and bottom, and it transforms into the Junction Tool. The easiest way to understand how it works is to see it in action. Here is a short video with two regions butted up together. Watch as the cursor changes to the Junction Tool. The boundaries are then simultaneously repositioned until a smooth edit point is found. All this while preserving the timing of the content in the time line. The only thing being altered are the region boundaries.

    once you get the hang of working with regions this way, it’s the fastest method i’ve found for editing. using the top 2 commands, it’s super easy to make the edges touch (enabling the junction tool), without moving content.

    check it out if you get the time!

    thanks for all the good info btw.
