MusicTechHelpGuy shows where Logic Pro hides your custom Step Sequencer templates, the file you need when working with third-party drum instruments.
Sampler-based drum kits don't auto-map to the Step Sequencer like Drum Machine Designer does, so producers build their own colorized, labeled user templates to skip the piano roll entirely.
He walks through the exact Finder path: Macintosh HD, Users, your username, Music, Audio Music Apps, Step Sequencer Settings, Templates. That's the folder to back up, zip, or move when switching computers.
He also demonstrates what happens if the file goes missing (the template vanishes from Logic) and confirms that simply dragging it back into the Templates folder restores full access.
