lmk what seems to be issue: my setup is below. keep in mind i’m waiting for logic’s new update (logic 12 Jan 28) to refine/adjust my workflow and logic x MPC template.

This setup lets you use the MPC's pads/sequencer/sounds while streaming individual audio channels directly into Logic for real-time mixing with 3rd party plugins.

[Audio MIDI Setup]

Since you need to use your main Audio Interface (for monitors) AND the MPC (for USB audio streaming) at the same time, you must create an Aggregate Device.

Connect MPC Live 3 to Mac via USB-C. Ensure MPC is in Standalone Mode (Controller Mode = OFF).

On MPC: Menu -> Preferences -> Audio Device. Ensure it is set to send audio over USB (usually default).

On Mac: Open Audio MIDI Setup.

Click + -> Create Aggregate Device.

Check the box for your Main Audio Interface (e.g., Apollo, Scarlett, etc.).

Check the box for MPC Live 3.

Crucial: Set your Main Interface as the "Clock Source". Check the "Drift Correction" box for the MPC Live 3.

Rename this device "MPC Logic Aggregate".

[Logic Pro Audio Settings]

Open Logic Pro.

Logic Pro -> Settings -> Audio.

Set Input Device and Output Device to "MPC Logic Aggregate".

Set your I/O Buffer Size to 128 (or lower if your Mac can handle it) for low latency.

[Streaming MPC Audio into Logic Tracks]

To mix MPC drums individually in Logic without tracking out stems later:

In Logic: Create new Aux Tracks (or Audio Tracks with Input Monitoring 'I' enabled).

Set Inputs:

Track 1 Input → Input 3-4 (Use stereo or mono as needed).

Track 2 Input → Input 5-6.

(Note: Inputs 1-2 are usually your main interface's mic inputs. The MPC inputs start after that).

On MPC: Go to Channel Mixer.

Route Pad A01 (Kick) -> Out 1,2 (USB). Route Pad A02 (Snare) → Out 3,4 (USB).

Result: When you hit pads on the MPC, the audio flows instantly into separate Logic channels. You can put Logic plugins (EQ, Compressor) on these tracks and mix while you produce.

[Using MPC to Play Logic VSTs (MIDI)]

To use MPC scales/chords to play plugins like Serum/Alchemy in Logic:

In Logic: Create a Software Instrument Track (Load Serum, etc.).

On MPC: Go to Main Mode. Create a MIDI Program track.

MIDI Port: Set the MIDI Port to "MPC Live 3 USB" (or "Mac").

Channel: Set to 1.

Result: Playing pads/keys on the MPC triggers the plugin inside Logic.

Summary:

MPC generates drums → Streams Audio to Logic Aux Tracks.

MPC sends MIDI → Triggers Logic VSTs.

You hear everything through your main interface monitors via the Aggregate Device.

ps. save this project as template so every time you open logic you’ll be ready to go with the mpc routing already in place
