Yes, i want to build an apple midi network through ethernet. Catalyst will then be controlling arkaos with midi (50-75m max) and powerpoint/keynote with MSC or midi (2m). I wrote MSC over 100m but it's only midi but that's the same principle in running long ethernet cables.

I know it's perhaps a bit complicated to do it like this but the show has already been made with these programs before i had catalyst. So if i have the time i will try to convert everything to that.

I will experiment a bit and let you know. But i cant do the long runs at home.

There are other options like QLab and DLight to get it all working but for the moment i really into cat.
