It can adjust the following parameters of the sound effects: Chorus: wet or dry mix, depth, feedback, frequency, delay, waveform, and phase. Compressor: gain, attack, release, threshold, ratio, and predelay. Distortion: gain, edge, postEQ center freq, bandwidth, and PreLowpass cutoff. Echo: wet or dry mix, feedback, left delay, and right delay. Flange: wet or dry mix, depth, feedback, frequency, delay, waveform, phase. Gargle: rate. Parametric equalizer: center freq, bandwidth, gain. Reverberation: in gain, reverb mix, reverb time, and highfreq RT ratio.
