RedInfoLmu read data from ambient light sensors
Only works on newer portable Mac models running OS X (10.4 or newer).
see also: RedInfoBat RedInfoSms
*kr(trig)
returns 2 channels. left and right sensor data.
zeros if no sensors installed.
trig asks for a new reading.
note: there is only one reading function internally. a trigger will cause global reading for all ugens.
it makes little sense to have this ugen running in multiple synths. use busses.
