Silence/zero input signal as a trigger (logical operators?)

This might be a basic question but I’m wrapping my head around how to allow silence (or lower volume) to act as a trigger/gate signal to fire for example a sample player. Basically, I need trigger signals when an input signal is low or zero. I know that Lojik package has some logical operators but cannot figure out how to do it. Or probably there’s an easier way? Would really appreciate any help!

Nothing extra is needed I think.

  1. Use an Envelope Follower to generate a signal corresponding to volume.
  2. Edit the desired trigger control to fire when the incoming signal (from the envelope follower) goes low by setting its output mode to ‘trigger on fall’.
