You can download the operation manual for CTR2-MIDI here. It will be updated when new versions of the firmware are released.

v1.01.00f of the operation manual includes new information about connecting to, and using CTR2-MIDI with Marcus’s iOS and MacOS apps.

NOTE: The latest version of Adobe Reader doesn’t know how to deal with the hyperlinks used in the Table of Contents. Open the PDF file in a browser for a better reading experience.


Map Files

This file contains the map files I use for SmartSDR, SDR-Control, and Thetis.

NOTE: Marcus has added a new CTR2 Controller device to his Tools menus. This device comes pre-configured with functions already mapped.
