feel free to ask questions, i'll answer best i can.
Enjoy.
1.
Download
http://www.thepiz.org/xt/midiOut.vst.zip
and
http://www.thepiz.org/xt/pizmidi20080203.dmg
Unzip/mount and install "midiOut.vst" and midiSimpleLfo.vst" to your VST folder.
2.
Go to "audio midi setup>midi devices>iac" and make sure you have at least one iac bus, and that "device is online".
3.
Open LIVE and go to "preferences>midi sync".
Set up live to recieve from iac like this:

4.
download, unzip and open:

5.
Now you have an instrument rack containing three lfo's. the first three macros turn them on and off.
switch off the second and third.
drop something in live you wish to modulate.
press command-m
pick the parameter you wish to modulate
press play
press stop
press command-m
press play
"LFO 0", the first of the lfo's within the instrument rack should now be modulating your parameter.
6.
repeat procedure for "LFO 1" and "LFO 2".
add more lfo's
info:
the three "x" tracks recieve midi from the three lfo's respectively.
lfo's are set to midi channel 16 cc0, cc1, and cc2.
EDIT: the only thing that seems to crash the setup is if an lfo is set to "slow random". that will shut down my live soon as i press play.
live's undo function is crippled
cpu usage on my mbp 2.33 duo is 5-6% with three lfo's running
as you may have noticed theres an "audio to cc" plugin in the vst pack. it works in a similar way. it just needs an audio input. not tested thoroughly.
