All CTR2 MIDI controllers (running CTR2-MIDI or CTR2-Dial firmware), must be configured to match the MIDI map of the app they are controlling. Typically, you’ll need to configure both the settings in the CTR2-Dial firmware on your CTR device and the MIDI mapping in the 3rd-party radio control app you are connecting your CTR2 device to.

Each of Marcus’ (DL8MRE) apps come with a basic map for the CTR2 Dial Controller in the Tools menu, but you’ll still need to edit these maps to match your CTR2 controller and your preferences. Thetis and most other 3rd-party apps don’t come with pre-mapped MIDI controls, so you’ll need to map these yourself.

You can import setting files (with the .txt extension) into CTR2-Dial using the Import option in the Settings menu. 3rd-party apps also have a map import options. Importing these maps is covered in the CTR2-Dial Firmware Manual. You can download it here.

NOTE: The setting files were exported from a CTR2-Quad. If you’re importing these files into a CTR2-Uno, CTR2-Duo, or one of the older single or dual-knob CTR2-Flex or CTR2-Dial units, you will need to set the number of knobs in the Settings menu and change the switch mapping to fit your unit.


Click the Download button below to download a zip file containing a collection of CTR2-Dial configuration files, 3rd-party app files, and spreadsheet with the mapping detail if you want to edit the CTR2-Dial configuration and 3rd-party app’s maps yourself.


These files should get you started. Feel free to make changes to your configurations to fit your operating style.
