Hi ADAM just Ań update I have put my feelers out re MIDI I might get lucky however here is a thought..you know the protocols of ethernet are widely available..it is my understanding that you can slave via ethernet anyway ? it does not only accomodate sync but upto streaming as many as 64 seperate audio Chanels unsure if this be mono or stereo haven't checked worse case scenario 32..so yea have a think about incorporating this option because I have a spare powerful IMAC heaps of ram huge ssd and heaps of horsepower to run QB and hooking it via ethernet is simple as can be..other wise stay tuned if I get a response from my investigation also you can use off the shelf go between interface for audio over ethernet such as AVB or sound flower the later has a shitty or non existent GUI where as AVB more sexy and configurable still though sound flower does incorporate the full 64 channel option.. cheers simon.
