The XT-CC Console Compressor is the most advanced XT compressor we've developed, with a full suite of professional-level features from our digital consoles including:

A scrolling history of your compressor action; a Program (Pgm) button that controls dynamics while retaining PUNCH; an innovative Depth control to limit the maximum gain reduction, a Sidechain EQ with 7 shapes to focus your compressor's sensitivity, and an External Sidechain input which allows you to choose any other track as the 'key' source for the XT-CC.

Requires: Mixbus or Mixbus32C.

Try the demo pre-installed in Mixbus or Mixbus32C (v7.2 or later).  Or view the plugin's manual page here
