How to configure Source-Connect 4 to send RTS via MTC and Reaper to send MTC

Follow the instructions below: 

1. In Source-Connect, click the “Send” button - it will turn green.
2. In “TIME REFERENCE INPUT”, select “MTC” and the name of your MIDI device (we had named it “MIDI Reaper” above). 
3. Select the appropriate FPS. 
   
4. In Reaper, go to Reaper > Settings > Audio > MIDI Outputs, and ensure that the MIDI device you created to send MTC is both enabled and has the clock enabled.
   
5. In Reaper, go to File > Project Settings > Project Settings tab and ensure that the Project Start Time is correct. In addition, go to the Video tab and make sure the frame rate is correct.
   
6. In Reaper, go to Insert > SMPTE LTC/MTC Timecode Generator. Then, double click the generator to access the SMPTE Generator Properties. In there, click, “Send MIDI (MTC)” and set both the frame rate and start times:
   
7. Once you are ready, play the timecode in Reaper. If needed, you can click the toggle repeat button next to the play button if you need a longer timecode.
8. Play the timecode in Reaper.
