Chapter 5.
Waveform Selector - Select from 3 waveforms shapes: Triangle, Sine and Async Sine.
Pre LPF - A lowpass filter placed in front of the feedback loop can be used to attenuate the high frequencies of the
signal. Lower values produce progressively darker tones.
Rate - Determines the frequency of signal modulation. Higher values equal faster rates.
Depth - Sets the depth of the pitch modulation. Higher values equal wider pitch variations.
Delay Time - Adds delay in front of the modulated signal. Higher values equal longer delay line times and can color the
chorusing effect.
Feedback - Controls the amount of effected signal fed back into the input to intensify the chorusing effect.
Reverb Send - ontrols the amount of chorus signal sent to the Reverb effect section.
Level - Adjusts the volume level of the chorus effect.
Pre Low Pass (Pre LP) - A lowpass filter applied to the signal feeding the reverb. Lower values produce progres-
sively darker colors by attenuating the high frequencies.
Pre High Pass (Pre HP) - A high pass filter applied to the signal feeding the reverb. Higher values progressively
attenuate bass frequencies.
Tone Freq. - Set the frequency for a high shelving filter that boosts reverb frequencies above the designated
point.
Tone Gain - Determines the amount of gain applied at the chosen Tone Freq and above.
Time - This parameter controls the reverb decay time (RT60). Larger values equal longer reverb times.
Damp -This high frequency dampening control places a lowpass filter after the reverb and can be used to
attenuate the high frequencies present in the reverb.
Pre Delay - Set the time between the start of the original signal and early reflections.
