Using the shoe Snap to Grid can make you make detailed work to the Envelope: You can set it shorter tho, and even chop the sound more precisely at certain level. That is set to -18dB and is more like a cut of the sounds that go below -18dB. The Cut you see in this Maximus Envelope. To be able to gate you need to set the proper Envelope in Maximus: You can turn off all bands in the Maximus, and only let Master Channel keep working for you. Mostly without the need for chopping, you can use Maximus. To be able to gate your breath or something that is noise in your vocal recording.
