Sorry guys, a bit more searching got me the answer you have to:- 1. Insert -> SMPTE LTC/MTC ... 2. Drag the right edge of the bar to cover the project length 3. Ctrl - F2 and select the Send MIDI option 4. Click io on the channel and select a MIDI Yoke channel as MIDI Hardware Output 5. open Chaingang and select this MIDI Yoke channel as your input You can use Maple MIDI instead of MIDI Yoke and get 12 channels instead of 8 (MIDI Yoke) with the Extra Ports version. It seems you can also do this over LAN, so you can have a separate PC on the same network running the video on its monitor receiving the MTC signal over the network. use Connect Reaper up as above only setp MIDITangle to send the MIDI Yoke to another one running on the other PC, Chaingang will setup the same way as before. I'm going to use this with ReaMote, so my main PC will run the Master Reaper and the bulk of my VSTs and the second PC run my video and extra VSTs if needed on ReaMote ... very nice!!! Stu
