Mixland Vac Attack

Gain reduction, gain, knee and mix with the whole sidechain EQ on page one, then LF push, HF push and THD on page two. Mapped to the left channel, so the plugin's Stereo Link needs to be on for the right to follow. That switch is on a button.

Tested with the device Somebody has run this into the gear it was made for.

The zip holds a mono and a stereo version, and the Roto needs both. Open ROTO-SETUP with the Roto in PLUGIN mode, then File > Import each file.
