RF Music has released Comp87 MB, a multi-band compressor VST effect plug-in for Windows.
Comp87 has a compress knob that automatically adjusts the threshold, input and gain to make it easier to get the desired results just by tweaking one knob. Other controls are also provided so the user can change them manually to suit their needs.
In the MB version of Comp87, the input signal is being divided into 3 bands (Low, Mid and High) and each band is being processed separately. Two frequency separators, Low-Mid (LMF) and Mid-High (MHF), control the frequencies in which the signal is being split. Each band has its own set of controls like ratio, compression, saturation, Stereo separation, Mix, ON/OFF, Solo/Mute, etc.
