It has a three arguments, the input 00008 patchpoint, the output patchpoint, and the release parameter. The release 00009 value controls how quickly the envelope responds to amplitude changes. It 00010 generally should have a value between 0.9 and 0.99. 00011 00012 This version operates at the sample-level. It is more responsive than the 00013 tick-level version (AmpenvfollowtUG). 00014 00015 Original Author: David A.
