6. Using 2 MP Controllers at the same time

Modified on Thu, 25 Jul at 2:22 AM

To use 2 MP Controllers, one must be used for the MP Host (Multi or Single, Instruments and FX) and the other one for the MP MIDI app and/or the Ableton MPH.

The first c1-xMP1 must be used for the MP Host and the second c1-xMP1-2 for the MP MIDI app and/or Ableton MPH.

When the 2 are connected you can choose the device from the right click menu of the MP MIDI app and/or Ableton MPH.

The MP Host does not have an option to select a C1-xMP1 device. Only the MP MIDI app and the Ableton MPH app have this option.

You cannot use 2 controllers at the same time for the MP Host (Multi or Single, Instruments and FX).

It does not matter if you are using different MP Controller models. The MIDI hardware is the same on all models.

On Windows, the USB port of connection to the computer matters.

Depending on which port you have connected each MP Controller, one of the two controllers will be found first by the operating system.

If you connect the MIDI of one controller first, then open the MP Host, and the MP Host will connect to the C1-xMP1.
Then connect the MIDI of the second controller, then open the MP MIDI or Ableton MPH, select C1-xMP1-2, and the MP MIDI will get that one.

If on the next computer reboot they are not assigned correctly swap the USB connection on the computer ports and that should do it. Every time you reboot, each controller will be assigned correctly.

On the Mac, open the Mac MIDI Studio and set the icon view (not the list view) and disconnect all MP Controllers. Select the C1-xMP1 and delete it, from the top menu, Edit > Delete.
Connect one MP Controller and it will appear in the MIDI Studio.
Load up and open the MP Host and check that the MP Controller is working normally. Unload the MP Host.

Then go back to the Mac Studio and connect the second MP Controller and it will also appear in the Mac Studio.
Double click on the second C1-xMP1 and rename it to C1-xMP1-2.

Load and open the MP MIDI app or Ableton MPH and select the second (C1-xMP1-2) on the list. Load and open the MP Host.

Save your DAW project, close it and then load up it up again.
The controllers should be assigned as you did when you saved the project.
If they are not assigned correctly just swap names, ie as on the image above, the left should be C1-xMP1-2 and the one on the right should be C1-xMP1. Save your DAW project, close it and then load up it up again.
The controllers should be assigned as you did when you saved the project.

Using the MP MIDI and Ableton MPH together on the second MP Controller

You can switch between the MP MIDI app and Ableton MPH while you have the second controller connected.

If you select c1-xMP1-2 on both MP MIDI and Ableton MPH, then selecting one of the two apps (from the Plugin Panel or the small window button) will automatically close the controller window of the other app.

If you select c1-xMP1 (the first controller) on one of the two then it will close the app window automatically upon opening an MP Host window (from the Plugin Panel or the small window button).
