Enable Track for the controller’s input port in MIDI/Sync Preferences, then select that port on the track. For the One’s DIN input, look for MPC.
Try these checks
- Open MIDI/Sync Preferences and locate the connected controller or the physical MPC input.
- Enable Track for that input, then select it in the track’s MIDI Input field.
- Match the MIDI channel. If using Auto monitoring in this workflow, record-arm the track before playing.
Diagnose it
Is the port visible in Preferences but absent from the track selector?
Yes: Enable its Track button.
No: Check the connection and whether the port appears in Preferences first.
What should happen
The enabled port appears in the track input list and can feed that track.
Why this happens
Global, Control and Track serve different routing jobs.
