This rack includes a third party plugin and requires bx_stereomaker. It is worth picking up when it goes on sale. I save this rack on my default audio and MIDI channels. It features true mono and true panning thanks to a Max for Live utility, along with low pass and high pass filter controls. The stereo width knob spreads sounds without ruining the mono signal and is worth its weight in gold. There is also built in overdrive distortion and a quick phase flip knob to help keep everything in phase.
