We'll be doing a gig next week with watchout and just been informed, that we'll need to have audio on some of the videos. It's like an "interactive" exhibition - midi triggered video playbacks in separate rooms on LED walls and projectors using 16 video output channels on 4 display computers. Each area has a separate midi trigger and the audio should only play on designated speakers.
I read some of the audio related topics, but not sure what would be our solution. As I understood the best way would be to have separate audio files and a multichannel audio interface.
