Wet/Dry The relative amount of input signal and fl anger signal that is to appear in the fi nal effect
output mix. When set to 0%, the output is taken only from the input (dry). When set to
100%, the output is all wet. Negative values polarity invert the wet signal.
Out Gain The overall gain or amplitude at the output of the effect.
Fdbk Level The level of the feedback signal into the delay line. The feedback signal is taken from the
LFO1 delay tap. Negative values polarity invert the feedback signal.
Xcouple How much of the left channel input and feedback signals are sent to the right channel
delay line and vice versa. At 50%, equal amounts from both channels are sent to both
delay lines. At 100%, the left feeds the right delay and vice versa. Xcouple has no effect if
Fdbk Level is set to 0%.
HF Damping The amount of high frequency content of the signal sent into the delay lines. This control
determines the cutoff frequency of the one-pole (-6dB/octave) lowpass
fi lters.
LFO Tempo Basis for the rates of the LFOs, as referenced to a musical tempo in bpm (beats per
minute). When this parameter is set to “System”, the tempo is locked to the internal
sequencer tempo or to incoming MIDI clocks. When it is set to “System”, sources (FUNs,
LFOs, ASRs etc.) will have no effect on the Tempo parameter.
LFO Period Sets the LFO rate based on the Tempo determined above: the number of beats
corresponding to one period of the LFO cycle. For example, if the LFO Period is set to “4”,
the LFOs will take four beats to pass through one oscillation, so the LFO rate will be 1/4th
of the Tempo setting. If it is set to “6/24” (=1/4), the LFO will oscillate four times as fast as
the Tempo. At “0”, the LFOs stop oscillating and their phase is undetermined (wherever
they stopped).
Noise Gain The amount of noise (dB relative to full scale) to add to the input signal. In many fl angers,
you can hear the noise fl oor of the signal being fl anged, but in the K2661, if there is no
input signal, there is no noise fl oor unless it is explicitly added. [Flanger 2 only]
Noise LP The cut-off frequency of a one pole lowpass fi lteracting on the noise injection signal. The
lowpass removes high frequencies from an otherwise pure white noise signal. [Flanger 2
only]
StatDlyCrs The nominal length of the static delay tap from the delay input. The name suggests the tap
is stationary, but it can be connected to a control source such as a data slider, a ribbon, or a
