"The Transgressor combines a transient designer with two equalizers. No big deal you say? Any EQ plug-ins will do? Au contraire mon frère. Transgressor not only lets you equalize the attack and sustain portions of the instrument’s envelope individually (yes, you read that right; attack can be equalized differently from sustain), but it also lets you dial in the specific low, mid, and high frequencies independently on each."
"Hybrid transient designer with two 3-band equalizers with selectable slopes"
A transient processor is a system that recognises the difference between the transient (attack) portion of a sound, and the bit after it, and can adjust the characteristics of either part of the signal.
