Wet/Dry The relative amount of input signal and effected signal that is to appear in the final 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 amount that the feedback tap is fed to the input of the delay.
HF Damping The amount of high frequency content of the signal to the input of the delay. This control
determines the cutoff frequency of the one-pole (-6dB/octave) lopass filters.
LF Damping The amount of low frequency content of the signal to the input of the delay. This control
determines the cutoff frequency of the one-pole (-6dB/octave) lopass filters.
Tempo Basis for the rates of the delay times, 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.
Diff Dly The length that the diffuser smears the signal sent to the input of the delay.
Diff Amt The intensity that the diffuser smears the signal sent to the input of the delay. Negative
values decorrelate the stereo signal.
LoopLength The delay length of the feedback tap in 24ths of a beat.
Fdbk Image Sets the amount the stereo image is shifted each time it passes through the feedback line.
Tap n Delay Adjusts the length of time in 24ths of a beat each output tap is delayed.
Tap n Shapr Adjusts the intensity of the shaper at each output tap.
Tap n Pitch Adjusts the frequency in semitones of the comb filter at each output tap.
Tap n PtAmt Adjusts the intensity of the comb filter at each output tap.
Tap n Level Adjusts the relative amplitude that each output tap is heard.
Tap n Bal Adjusts the left/right balance of each output tap. Negative values bring down the right
channel, and positive values bring down the left channel.
