It would be nice if there was a way of triggering the built in SMPTE generator via comment macros, even better if it could output SMPTE as well, either as audio or as MTC
Nice idea... For the meantime as a workaround, get yourself a MIF4 from Rosendahl. Works native with HOG OS via USB, so it can be used as Midi Interface as welll for a Roadhog. And you control that via Midi-Strings comment macros
