Is there a way to transmit the "play/stop/record/loop" commands to both DAWs so that they play in sync?
Because of Record's lack of MIDI-Out support AND not being able to take incoming audio from external sources while in ReWire mode, I'm trying to work my way around it by feeding Reaper's output-channels into some of Record's input-channels (via Soundflower). It's not very practical, but I will have to write MIDI clips in Reaper (for VST instruments) and then MIDI clips in Record (for Record & Reason devices).
But now comes yet another issue, how can I sync both together? Does it require an external hardware MIDI-clock of some kind?
