First of all, thank you for making Q3 so intuitive and fast to use. I love being able to equalize the attack and sustain portion of a sound differently.
That said, I think Q3 would really benefit from a fast attack option. The current attack time seems to be roughly 10 milliseconds and that's too slow to use the dynamic EQ to pass the transients unaffected and only EQ the tail. What instead happens is that the very initial transient is EQd according to the static gain and the dynamic gain only catches up in the later part of the attack stage. An easy example would be clave track where you want to preserve the attacks as-is but decrease the sustain level.
