Note that the MP Controller must be connected to the computer for the Control Surface app to work
--- ##### MIDI PORT Installation and Configuration To use the MP MIDI on Windows, you need to install a virtual midi port software. We recommend [loopMIDI ](https://www.tobias-erichsen.de/software/loopmidi.html)which is a free utility software. There are others as well like [LoopBe30](https://www.nerds.de/en/loopbe30.html). LoopMIDI allows you to create many virtual ports you need and set custom names for each port. For the Reason Control Surface we need two ports, one for sending MIDI CC and another one for receiving MIDI CC messages. After you install loopMIDI, open loopMIDI and add a port, name it "FROM REASON CS", then add another port and name it "TO REASON CS" [](https://kb.mpmidi.com/uploads/images/gallery/2025-10/8koaTvb0gkKh4TMJ-image.png) [](https://kb.mpmidi.com/uploads/images/gallery/2025-10/BqQhAmGELKf4UEon-image.png) so it will look like this: [](https://kb.mpmidi.com/uploads/images/gallery/2025-10/QGr1ZIUZ0V9227Vj-image.png)We have created a launcher app to start Reason and the MP Controller Reason Control Surface. The installer places these apps on your desktop. The launcher will start both applications, the Control Surface app and Reason. Once you close Reason it will close the Control Surface app as well.
There is a Launcher for Reason 13 and one for Reason 14
Run the Reason Control Surface launcher from your **Desktop** and it will start the control surface app and Reason.

Right click on the empty area above the buttons and the following menu will appear. Select the last monitor in the list.

[](https://kb.mpmidi.com/uploads/images/gallery/2025-10/GE58maQyM7Am9YPt-image.png) Select the MP Controller from the list Select the available MIDI ports. Select **TO REASON CS** as the **input port** and **FROM REASON CS** as the **output port**. It should look like this and click OK. [](https://kb.mpmidi.com/uploads/images/gallery/2025-10/vszudMMasFenxysR-image.png)No other application should be using these virtual MIDI ports.
When you run the Launcher app to start the apps and then you close Reason, the control surface app will quit as well after a couple of seconds.
--- To view the version or quit of the Reason Control Surface right click on the bar icon [](https://kb.mpmidi.com/uploads/images/gallery/2025-10/whdwUtcLNmDYacLV-image.png) To quit click OK on the popup window: [](https://kb.mpmidi.com/uploads/images/gallery/2025-10/tktZ13iA9uX8zi3C-image.png) ---When running the Launcher it takes a few seconds for Reason to send all the necessary data to the control surface. You can then select any device or track to control it.
