I've got a goodie for ya, gives a nice expressive vibrato. I was thinking about the way
a violinist gets so much expression with just two physical controllers, the bow
and the finger on the string: the finger controls the speed and depth of
vibrato, and the bow controls tone and volume. So the samplist wants to
control pitch amplitude and lfo rate with one controller, and filter frequency
and volume with another.
 
cord - source > destination : amount

00 - pitchwheel > CO3 amt : +1%
01 - pitchwheel > CO4 amt: +42%
02 - pitchwheel > LFO1Rt : +3%
03 - LFO1~ > pitch : 0%
04 - LFO1~ > finepitch : +8% 
05 - modwheel > filter frequency : add to taste :-)
06 - pitchwheel > CO7 amt : smallish%
07 - LFO2~l > AmpVol : 0%
same for LFO2 rate as for LFO1 rate, though maybe use lag on it, and I've got
both LFOs set to 2.29 rate, sine wave.

SO, your left hand is free to operate both pitch wheel and mod wheel at the
same time. The pitch wheel controls both depth and rate of the vibrato, and the
modwheel controls tone. If the filter frequency (low pass) is set low enough,
the modwheel will control the volume too. If your keyboard has a sensitive
enough pressure response  you'd probably be better off using that than the mod wheel. Hope you like it!
