I am making an installation in which I am projecting around a room using mostpixelsever and I want to switch between processing sketches upon certain triggers (whatever these might be). I would also like to switch between video (probably HD) and create some kind of responsive video in which multiple videos are loaded in buffers and sound reactivity causes a jump between videos (probably using GSvideo). 

I wondered what system people would recommend using. For example I know that Open Frameworks would probably be more efficient, but I am having trouble with OF and struggling to learn C++. 

Firstly, is it possible to switch between processing sketches?

Secondly, what is the best way to trigger switches between multiple videos using GSvideo (as I have checked the forums and this has been asked but seemingly not answered)? 

If anybody has any suggestions then please let me know.

Thank you in advance,

Jamie
