Hi, not totally relevant but a nice idea i think. 4-way video mixer with midi control which might work in the short term. Set-up a cuelist on your console that would switch video inputs on the mixer. www.lotech.co.nz/edirol/v1/
You can link two together to get 6 inputs and 6 outputs, but after that linking them becomes really unweildly.
For most applications 4-6 outputs is OK, but many more inputs are needed.
There are quite a number of S-video switchers out there that can be controlled via RS-232. I've seen specs on customizable matrix-es of up to 256 inputs by 256 outputs (can you imagine:eek: )
I've never really had need of more than 16 x 16 yet, but I'm sure the day will come when I do.
I've added this request into the database as #10491. The biggest issue I see is that Serial Ports are rapidly disappearing off PC's. So we would likely have to also implement support for some specific USB to RS232 converters.
