Press has six styles: Clean for transparent control, Punch for drums, Opto for vocals, Vintage with colour and feedback, Bus to glue the mix and Master for gentle work on a whole track. The scrolling graph shows input, output and gain reduction over time, and the curve next to it shows the threshold and knee. There's lookahead, hold, auto release, parallel compression (Mix) and an external sidechain for pumping to the kick.
