Audio Assault has released the Transfreak Transient Designer plugin for Mac OS X and Windows (VST2, VST3, AU, AAX & RTAS).
Transfreak includes improved transient control from Multi-Transient/Transient as well as separate 2x controls for attack and sustain. Transfreak also includes equalizers acting on the attack/sustain designed to pinpoint the character a user wants when boosting/removing attack and/or release.
Transfreak includes a reverb that acts solely on the sustain, and can be used to change the character of a room or even replace it altogether. Transfreak has saturation with pre/post filters, tone and mix controls and an equalizer acting on the stereo signal. Transfreak also includes a clean mode switch when pushing attack to extremes.
