In this article we will go through the steps to map your MPC plugin instrument parameters to your MIDI controller in MPC in Standalone mode and within MPC 2.0/MPC Beats.
Overview:
You can use the MIDI Learn function to assign external MIDI controllers to various parameters in your specific MPC project:
• Mixer parameters such as volume, pan, mute, and solo for tracks, returns, submixes, and main outputs.
• Pad parameters (for drum tracks only) such as tuning, filter and amp envelopes, layer settings, LFO settings, and velocity.
• Track parameters, which depend on the track type.
• Insert effects parameters, which depend on the effect type.
These assignments will be saved with your MPC project.
MPC Standalone:
1. On your MPC, go to Menu > MIDI / Sync and ensure you MIDI controller has been set to the following:
Input Ports: Global, Control & Track (ON)
Output Ports: Sync & Track (ON)

2. Load a plugin instrument
3. Go to the Main Menu, and enter MIDI Learn (MPC 3) or MIDI Control: MIDI Learn (MPC 2)

4. Tap LEARN (MPC 3) or LEARN + ENABLE MAPPING (MPC 2)

5. Tap the + icon in the top left section of the screen
6. Tap Source & select Program > Plugin 001
7. Tap Target & select Program.
From here, select the plugin parameter you wish to map

8. Once selected, manually move the parameter on your MIDI controller that you wish to apply the mapping to. The MIDI Type, Channel, and CC of the Fader/Knob you moved will appear next to your chosen parameter

9. Repeat steps 5 to 8 until all plugin parameters have been mapped to your MIDI controller
Once you have completed your mappings, return to you project by pressing the Main button.
That's it, your controller is now mapped!

7) Then manually move the parameter on your MIDI controller that you wish to apply the mapping to. The MIDI Type, Channel, and CC of the Fader/Knob you moved will appear next to your chosen parameter
In this example we have mapped the first four drawbars in the Organ plugin:
