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.
CTR2-MIDI mode
This manual is for the normal MIDI control mode in CTR2-MIDI.
CTR2-MIDI Flex WiFi Mode
This manual if for the new CTR2-MIDI Flex WiFi mode. This mode allows CTR2-MIDI to connect to, and control, your Flex radio over your WiFi network – no 3rd-party app required.
App Maps and Excel Worksheet Files
CTR2-MIDI Normal Button App Map Files
This file contains the map files I use for SmartSDR, SDR-Control, and Thetis when running CTR2-MIDI in normal MIDI controller mode without the Extended Button function enabled (i.e. 6 buttons/12 functions).
CTR2-MIDI Extended Button App Map Files
This file contains map files that can be imported into SmartSDR for iOS/MacOS and Thetis when using CTR2-MIDI in Extended Button mode. Each map has 48 button functions. Download the Excel spreadsheets below for templates to manage the button assignments. If you create map files for other program, send them to me and I’ll add them to this file.
CTR2-MIDI Knob and Button Assignment Excel Worksheets
This file contains Excel worksheets that make it easier to document custom knob and button assignments for both CTR2-MIDI MIDI normal and extended button modes and Flex WiFi mode. You can print them out to use as a training aid while you’re getting familiar with the button functions on each knob mode.
