MIDI Keyboard Not Working in Logic Pro
Three years ago I plugged a MIDI keyboard into my Mac mid-session and Logic Pro just sat there. No notes, no meter movement, nothing. My Arturia KeyLab 61 was powered on…

Choose the symptom you can reproduce, then run the shortest safe test. Random preference changes create more variables. Reinstalling Logic Pro rarely fixes an interface driver, a damaged project, or an incompatible Audio Unit.
- Protect the session.Save a copy and note what changed before removing devices, plugins, or settings.
- Repeat one short test.Use the same project section, track, or input so each change produces useful evidence.
- Cross a boundary.Try a new empty project, built-in audio, or a session without third-party Audio Units.
- Change one thing.Do not reset settings, update several drivers, and rebuild routing in the same pass.
- Keep the result.Record the working device, buffer, plugin, project, and macOS state before restoring extras.
Apple’s current Logic Pro troubleshooting sequence also starts with backups, updates, compatibility, external devices, built-in audio, and third-party Audio Units before destructive steps.
Logic Pro troubleshooting FAQ
What should I check first when Logic Pro stops working?
Save a copy, note what changed, restart, and repeat one short test. Then try a new empty project to separate a project fault from an app-wide problem.
Should I reset Logic Pro settings immediately?
No. Reset only after simpler isolation tests and after recording custom preferences and exporting key commands. A reset can hide the original cause and create extra setup work.
When should I reinstall Logic Pro?
After device, project, plugin, and settings tests point back to the application itself. Reinstalling does not repair incompatible hardware, drivers, or third-party plugins.
Why does a problem happen in only one project?
The project may contain a damaged asset, unusual routing, a problematic plugin instance, or a project-level setting. Duplicate it and remove one boundary at a time.
