In/Out When set to “In” the algorithm is active; when set to “Out” the algorithm is bypassed.
Out Gain An overall level control of the EQ Morpher output.
Out Pan Provides panning of the output signal between left and right output channels. A setting of
-100% is panned left and 100% is panned right. For EQ Morph, this is a stereo panner
which pans the entire stereo image as is done with the input sends on the INPUT page
when set to the “SP” mode.
Out Width The width of the stereo fi eld is controlled by this parameter. A setting of 100% is the same
full width as the input signal. At 0% the left and right channels are narrowed to the point
of being mono. Negative values reverse the left and right channels. This parameter is
available in EQ Morpher and not Mono EQ Morpher.
Morph A>B When set to 0% the “A” parameters are controlling the fi lters, and when set to 100%, the
“B” parameters control the fi lters. Between 0 and 100%, the fi lters are at interpolated
positions. When morphing from A to B settings, the A fi lter #1 will change to the B fi lter
#1, A fi lter #2 moves to B fi lter #2, and so on.
FreqScale The fi lter frequencies for the A and B parameter sets may be offset with the FreqScale
parameters. After setting the fi lter parameters, the FreqScale parameters will move each of
the four fi lter frequencies together by the same relative pitch.
For the two fi lter sets A & B, there are four fi lters 1, 2, 3 and 4:
Freq The center frequency of the bandpass fi lter peak in Hz. This frequency may be offset by
the FreqScale parameter.
Width The bandwidth of the bandpass fi lter in octaves. Narrow bandwidths provide the most
convincing vocal sounds.
Gain The level of the bandpass fi lter output. At 0 dB, a sine wave at the same frequency as the
fi lter will be neither boost not cut. At settings greater than 0 dB, the (hypothetical) sine
wave is boosted, and below 0 dB the sine wave is cut. Signals at frequencies other than the
fi lter frequency are always cut more than a signal at the fi lter frequency. The amount that
other frequencies are cut depends on the bandwidth of the bandpass fi lter.
