CHOP Execute: select the CHOPS. Channels.

code:

 1# me - this DAT
 2# 
 3# channel - the Channel object which has changed
 4# sampleIndex - the index of the changed sample
 5# val - the numeric value of the changed sample
 6# prev - the previous sample value
 7# 
 8# Make sure the corresponding toggle is enabled in the CHOP Execute DAT.
