Hi all, I wish to convert an incoming audio signal (from ableton live) into Open Source Control messages, and then feed these messaged back into live so that I can control parameters on my effects. I am using OSX Lion, and have the IAC Drivers working.

is this possible, and if so where do I begin?

look at the [env~] object and its helpfile perhaps, as well as the C07.envelope.follower.pd patch in Pd's doc folder. More complicated analyses could be done using the fiddle~ and bonk~ external objects, that are included in the Pd vanilla distribution. Some scaling of the data derived would have to be done using simple math objects like [* ] and [+ ], perhaps also [clip ]. See the patch help-intro.pd for an overview of Pd objects. In order to send these values over OSC to ableton (a)live, use [oscformat] in combination with [netsend -u -b] and read their respective help patches.
