ControlIn: read an external control source
ControlIn.kr(source, lagTime)
For more info, see the ExternalControlSource help file.

source - an instance of ExternalControlSource which includes MIDI and Mouse sources, or anything
else that responds to the value message with a Float.
lagTime - an exponential lag time used to smooth the signal. This is useful for de-zippering Mouse
and MIDI controllers. A lag time of zero means no smoothing is done.
