The Stellar emulations are modelled upon particular vintage compressors in which the attack and release time controls functioned opposite to the way they normally do. For the majority of compressors, rotating an attack or release time control clockwise would increase the release time. For these particular vintage compressors, however, the release time is longest at the fully counter-clockwise position, and shortest at the fully clockwise position. This peculiarity has been emulated in the Liquid Mix emulation in order to maintain the highest level of authenticity.
