To meet this objective and to be ready for all the situations: drums, guitars, bass, vocal and much more. FAC Transient includes, in addition to the classic amplification or attenuation of the attack and sustain portion of your instrument, a fine control of the detection circuit involved in the processing. Without going into technical details, there are three envelopes built from their respective detection circuits. The first one is the contour of the input signal, this includes similar processing available in Maxima and brings you control of the treshold, time and detector algorithm. The second and third one define the contour of the attack and sustain portions and brings you a total control of the depth and duration of each stage. FAC Transient gives you all you need to design the shape of your instruments and provides them the place they deserve in your mix.
