Stereo Flange Dual Flange
FX Lvl Controls the signal input level fed to the Module. Varies from OFF to 100%.
Dry: Lvl Controls the level of the dry (uneffected) signal. Ranges from OFF to 100%.
Balance Controls the left/right positioning of the dry signal in the stereo soundfield. Varies from -99 (all left) to
99 (all right).
Speed Controls the Low Frequency Oscillator (LFO) speed of the flanger.
Range of this control is from 0.06 to 16 Hz.
Depth Adjusts the intensity of the flange effect. High settings of DEPTH combined with high settings of FDBCK
produce dramatic, synth-like results. Varies from. 0 to 30 milliseconds.
FdBck Controls how much of the flanged signal is fed back to the input of the Module. The FDBACK Parameter
is what gives flangers their distinctive voice. Flangers are capable of both positive and negative feedback
loops, so experiment to find the sound you like best. Ranges from -99% to 99%.
WvFrm
Selects which waveform the LFO follows. Options for this control include sine, triangle, SP1 (Special 1),
and SP2 (Special 2). The sine wave setting is probably the most easily recognized, but the smooth
response of the triangle wave or the intensity of SP1 or SP2 typically produce better results.
DlyA - B Controls the delay time of flange voice A or B. Shoter delay time settings produce a more dramatic,
deeper sweeping sounds. Ranges from 0 to 60 milliseconds.
Out A - B Adjusts the overall level of flange voice A or B. Ranges from OFF to 100%.
Pan A - B
Controls the stereo soundfield placement of flange voice A or B. Varies from -99 (all left) to 99 (all right).
✓
Out L - R Adjusts the level of the left or right side of the flanger. Ranges from OFF to 100%.
