If you’re working with MPC in Logic Pro X and notice that the multi-output option is not showing up, there could be several reasons for this. Below are some steps you can take to resolve the issue:


1. Ensure Proper Plugin Installation in Logic Pro X

When adding the MPC plugin to Logic, it’s important to manually select the multi-output option at least once. If you’ve previously added MPC as a plugin, it may default to stereo, and you won’t see the multi-output choice.

Steps to ensure proper setup:

  • Create a new track and choose Software Instrument.
  • Navigate to AU Instruments > Akai Professional > MPC.
  • Select Multi-Output (16x Stereo).

Once this is set up, the next time you add MPC, it should remember this configuration.


2. Confirm the MPC Software Driver Installation

During the MPC Software installation, a crucial step involves installing the driver. This driver allows your MPC to communicate properly with Logic Pro.

Steps to check the driver installation:

  • Run the MPC Software installer again.
  • Ensure that all the checkboxes (especially the second checkbox for the driver) are marked green. 
  • If the driver is not installed, you may see it marked red. Make sure to install the driver for your specific MPC model and restart your computer afterward.

Tip: If you have multiple MPCs, repeat this step for each model to ensure the drivers are installed for each device.


3. Check Your MPC Software Version

It’s possible that outdated software or an older operating system could be causing the issue. Ensure both Logic Pro X and MPC Software are fully updated.

Steps:

  • Check for updates to MPC Software from the MPC software installer. You will also receive a message from the MPC screen when you launch the software that informs you a new update is available.
  • Ensure that your macOS version is compatible with the latest MPC software. It may not need to be the very latest macOS version, but it shouldn’t be too old.


4. Additional Tips

If none of the above steps solve the issue, try the following additional steps:

  • Rescan Plugins: In Logic Pro, go to Preferences > Plug-In Manager and rescan all your installed plugins to ensure Logic recognizes them.
  • Reinstall Software: Reinstall the MPC software and ensure all components are correctly installed.
  • Template Use: Once multi-output is set up, you can create a template in Logic Pro X to easily access it in future sessions.


These troubleshooting steps should help you restore the multi-output functionality for MPC in Logic Pro X. The most common issues arise from improper plugin installation, missing drivers, or outdated software versions. By following the steps above, you should be able to resolve the issue and get back to making music.
