Feel free to add it yourself, the manual is publicly editable: http://livesdoc.wetpaint.com/ you just need to create an account there and request editor access. > The other concept, I'm thinking in to use music reactive plugins in real > time in LIVEs.

(In fact for the main part of my research project I will be doing things the other way around - analysing video and then attempting to generate audio from that...:-D So eventually, LiVES will have an automatic soundtrack generator...)
