i was able to record a video mix by just using the recorder option. i am not clear of what people use the syphon app for? i was under the impression the syphon app recorded live video mix sets that also recorded the audio... i did not get this when using the syphon app. also i was able to use the "record" function on ME and setting the the record channels to 9&10, 9&9 & 10&10 and it works like a charm. my specs are 2018 Macbook Po 15 inch i9 processor vega 20 gpu 32 gb of ram 1tb ssd serato dj pro 2.1 mix emergency 3.2 cheers! hopefully someone can shed some light on the Syhon App and what its purpose is
