Fast answer

Enable Track for the MPC output and choose it as the MIDI Program’s output. Sync sends timing, not the track’s notes.

Try these checks

  1. In MIDI/Sync Preferences → Output Ports, enable Track beside MPC. Leave Sync enabled only if that synth also needs timing.
  2. Select the MIDI Program and choose MPC in its MIDI Output field.
  3. Match the output channel to the synth and connect MPC MIDI OUT to the synth’s MIDI IN.

Diagnose it

Does the synth follow clock but ignore the track’s notes?

Yes: Check Track and the MIDI Program’s output assignment.

No: Check the physical connection and the receiver’s channel too.

What should happen

The selected MIDI Program can send notes to the enabled output and channel.

Why this happens

Akai separates per-port timing from per-track note routing.

If it still doesn’t work
