Hi Simon, Where Can we see the video patches you talk about? I´m very interested.

Thats why I thought about having a machine per video > output connected to a LAN and synchronised via OSC. I've done it often, the basic principle for keeping the LAN machines in constant frame sync, allowing scrubbing etc, is each projector has a slave patch that uses [pix_film] to play by frame number rather auto, and receives those frame numbers (via [netreceive]) from a master patch which has a metro counting the frames and which plays any sound required. Works very cleanly and doesn't put much data through the network. Two [pix_film] Gem-chains in each slave will give you X-fades etc. I could post the set of patches which add quite a bit more functionality than that if you like, I've built up a collection over several projects. simon -- Enrique Franco Telefono/Phone: +572 5552334 ext 388 Webpage: http://richie.idc.ul.ie/~enrique/ http://www.iua.upf.es/~ffranco/pfm.htm
