Molot, by vladg/sound, is described as a compressor that will add lots of color to your sound and is not for beginners. Although it was designed as a buss compressor due to the relatively high cpu load and the overall sound of the compressor, it is also right at home on individual tracks if your system can handle the cpu load. Molot can not only provide compression, but also saturation characteristics and harmonics as well as oversampling with non-linear phase response to give depth. Those elements can be switched off under the hood, but they are on by default.
