nice - good to read directly from there...

the fps start at about 16 and drop to 9ish when too many recursions
are loaded - will play around with the buffer size to see how that
will help.

thanks - I am doing a short live event for new year - mainly mixing
music  and playing around with fluxus with this code (not really live
coding yet ) - not sure if I'll integrate the osc part this time -
anyhow I will video some part of the event and post it online ;)

thanks again
