Touch Tracks is a way to play multiple MIDI regions and even folders containing MIDI information using a keyboard controller. This was originally a pretty fun way to audition a song when the world of Logic was all MIDI. We could take whole sections of a song and play them back in any order we liked.
Now that we live in a world of audio and MIDI, Touch Tracks can seem a little less exciting. Especially since we need to use the Environment window to get to them. Even so, the possibilities for the Touch Tracks environment object have become interesting again since the ability to convert audio into sampler tracks.
I’ll just have to show you how they work, and we’ll see what possibilities you come up with!
Ok, first things first: We need to open up an environment window and from the local New menu, select Touch Tracks.
We are presented with the Touch Tracks screen. Touch Tracks objects automatically become available as an assignable track in the Arrange window, and the Touch Tracks window that popped up will float, even when we close this environment window.
In the arrange window, take a new track (it can be anything that isn’t being currently used) and hold Control down while selecting the icon in the track list. This will allow us to see the Environment layer that the Touch Tracks are in, and reassign the track accordingly.
Go to the Apple Loop Browser, and pick some green Apple Loops to drag into the Arrange window. Try a PIano, Bass, and Drums combo. Maybe add a synth pad. Knock yourself out.
Now simply drag the MIDI regions on to the open Touch Tracks window. Be sure to drag the regions one by one on to the keyboard on the left side of the Touch Tracks window. Here’s what it should look like if you were to drag regions onto C3, D3, and E3:
Now set the playhead after the last region has ended in the arrangement, and hit play. Be sure you have the Touch Tracks track selected in the Arrange window. While Logic is in play mode, you will be able to trigger the MIDI regions one at a time. Each Region is now assigned to its own group. You should turn all of the group settings to ‘Off’ or ‘0’ to allow all regions to play at once.
You may notice some settings changing on other touch track note values. I usually ignore them.
Now that we have determined that the touch tracks are working, mute the regions in the Arrange window. The touch tracks can be used exclusively.
If you pack the regions into a folder, you may play the entire folder on a single key. Try selecting all of the regions in the arrange window, unmute them, and the pack them into a folder using Region > Folder > Pack Folder.
Now the entire folder will play on a single key in Touch Tracks. Keep in mind that this folder can be transposed now as a whole, which can have mixed results. You need to be sure that in the inspector for a drum track, the No Transpose option is checked:
This will keep your drums from getting transposed as well.
Make sure to experiment with the other settings in Touch Tracks:
Although Touch Tracks can be slightly challenging—like a sustain message holding because you released a key before the region ended... (awkward!)—it can also be a lot of fun. I highly suggest playing around with them.
