/ 9. STEREO FLANGE / This effect produces a pleasant "swirling" sound which can effectively thicken and add warmth to the sound of an instrument. The flanging effect is produced by MOD. DEPTH (dB) DIRECT SIGNAL L(R)/R(L) [MOD. DLYJ (TIME) Modulation Frequency (MOD. FRQ): 0.1 Hz - 20.0 Hz Sets the speed of modulation, and hence the rate at which the effect varies. Modulation Depth (MOD. DEPTH): 0% - 100% Sets the amount of delay time variation, thus adjusting the depth of the effect. Modulation Delay (MOD. DLY): 0.1 ms - 100.0 ms This sets the basic delay time from the initial direct sound to the beginning of the flange effect. Feedback Gain (F.B. GAIN): 0% - 99% Determines the amount of flange signal which is fed back to the input of the processor for further modulation. More feedback increases the overall cornplexity, "strength" and decay time of the effect. / 10. CHORUS / Like flanging, chorus serves to thicken the sound of an instrument, creating the effect of several instruments playing at once. The chorus effect splits the incoming signal into three signals placed at the center left and right of the stereo image. The delay time and level of the three signals are then modulated by the LFO (Low Frequency Oscillator). 1dB) DIRECT SIGNAL AM DEPTH Modulation Frequency (MOD. FRQ): 0.1 Hz - 20.0 Hz Sets the speed at which the effect varies. Delay Modulation Depth (DM DEPTH): 0% - 100% This sets the amount by which the delay time of one delay signal is varied in relation to the other, and thus the depth of the CHORUS effect. Amplitude Modulation Depth (AM DEPTH): 0% 100% Sets the amount by which the amplitude (level) of the input signal is varied. / 11. STEREO PHASING / Phasing is basically a "gentler" version of the flange effect, lending a smooth, animated quality to the original sound. (dB) L L,R R MOD. DEPTH .4 II MOD. DLY (TIME) Modulation Frequency (MOD. FRQ): 0.1 Hz - 20.0 Hz Sets the speed at which the phasing effect varies. Modulation Depth (MOD. DEPTH): 0% - 100% Sets the amount of delay time variation, thus adjusting the depth of the effect. Modulation Delay (MOD.
