No, I haven't had any trouble outputting Resolume via HDMI. It's just that I work with video, and have had situations very close to disasters because of HDMI issues of all kinds... SDi just feels more safe.
BUT if it introduces more latency, it's probably not a good idea anyway, since I want to input live video...
Thank you so much for looking into this. If you fint an easy way to make the T-Tap an option, it is of course very nice (always feels good to have as many plan B's as possible:)
