10. Mac - C1-xMP1 not showing up in the System Report

Modified on Fri, 17 Jan at 2:18 AM

The MIDI port of the MP Controller should be connected with a USB-A interface on the Mac and does not require any drivers to be installed as it is a USB MIDI class compliant device.


If you are connecting to a USB-A port directly to the Mac and C1-xMP1 still does not show up in the System Report, first check using another cable.


System Report > USB Tree


If you are certain the problem is not with the cable you need to check the internal micro-USB bridge port cable that connects on the MIDI board. 

  • To get to that port, you need to unscrew the bottom cover.
  • Open up the bottom cover by unscrewing the bottom screws. 
  • Disconnect the microUSB cable from the C1-xMP1 and connect the data cable directly on the Mac.
  • Disconnect by pulling gently the microUSB cable and connect it again.  Do not bend the microUSB connection as it is sensitive and you run the risk of permanently damaging the board.




Close and reopen the System Report. If it is still not showing in the System Report, connect it on another computer, preferably a Windows computer and check the device manager to see what device is shown when it is connected.


Bypassing the internal USB Port (Bridge port)

The problem may be with the bridge port. You can try to bypass the internal port of the C1-xMP1 and connect it directly using a microUSB to USB-A DATA Cable like this


Please note that not all microUSB cables are data cables. Many are just charging cables and these will not work. Ensure you are using a data cable.
