Stereo Chorus
Chorus samples the input, slightly detunes it and mixes it with the original
signal to produce a somewhat thicker, shimmering sound. Use it to thicken up
background vocals, or to double the sound of brass and woodwind instruments.
Where as DELAY L/R set the total amount of delay for the left and right channel,
WIDTH determines the amount of modulated delay. SPEED sets the modulation
speed. MIX adjusts the balance of the dry and wet signals. You can further sculpt
the sound by trimming some of the low and high end from the effected signal
with the LO and HI CUT knobs. Additionally, the PHASE knob can tweak the
phase offset of the LFO between left and right channel and the SPREAD knob
adjusts how much of the left channel is mixed into the right and vice versa.
Finally, the WAVE knob blends between the "Danish-style" digital triangular
chorus sound and the classic analog sine wave.
Stereo Flanger
The Flanger emulates the phase-shifting sound (comb-filtering) originally
created by applying pressure against the flange of the reel on a tape recorder.
This effect creates a unique "wobbly" sound that is quite dramatic when used on
vocals and instruments.
The controls of this effect are nearly identical to the Chorus effect block.
Additionally, the FEEDBACK can be adjusted with positive and negative amounts
and also band-limited with the FEED HC (high-cut) and FEED LC (low-cut) knobs.
Stereo Phaser
A Stereo Phaser, or phase shifter, applies multiple STAGES of modulated filters to
the input signal to create a "notch" in the frequency response, and then applies
a MIX with the original for a "swirling" effect. Use the Stereo Phaser to add a
"spaced-out" sound to vocal or instrument tracks.
SPEED adjusts the LFO rate and DEPTH sets the LFO modulation depth. The BASE
knob adjusts the frequency range of the modulated filters. The resonance is
adjusted with the RESO knob. The WAVE knob shapes the symmetry of the LFO
waveform and PHASE dials in an LFO phase difference between the left and right
channel. The modulation source can also be the signal envelope, which produces
vowel-like opening and closing tones. The ENV MOD knob adjusts how much this
effect takes place (positive and negative modulation is possible), and the ATTACK,
HOLD and RELEASE knobs all tailor the response of this feature.
Dimensional Chorus
The Dimensional Chorus offers the most user-friendly and classic sounds,
best described as "space" and "dimensional". The 4 MODE buttons can
be engaged individually or simultaneously for light chorus or very thick,
exaggerated modulation.
Mood Filter
The Mood Filter uses an LFO generator and an auto-envelope generator to control
a VCF (voltage-controlled filter), as well as a side chain function where the
channel B signal controls the envelope of channel A. When applied to electronic
instruments, the Mood Filter can be used to emulate the natural sound of
acoustic instruments. (Inspired by the MiniMoog)
This filter can be modulated with the signal's envelope using the ENV MOD
(with positive and negative amounts), ATTACK and RELEASE knobs, or the
LFO can modulate the filter. The WAVE knob selects between 7 different wave
forms – triangular, sine, saw plus, saw minus, ramp, square, and random.
The PHASE can be off set by up to 180 degrees. The SPEED knob adjusts the rate
of the LFO and the DEPTH adjusts the amount of LFO modulation. Adjust the
resonance of the filter until self-oscillation with the RESO(nance) knob.
BASE adjusts the range of the filter from 20 Hz to 15 kHz. The MODE switch
selects between low pass (LP), high-pass (HP), band-pass (BP) and Notch. Use the
MIX knob to blend the effected signal with the dry sound. With the 4 POLE switch
engaged, there will be a steeper slope than the OFF (2 pole) setting. The DRIVE
knob adjusts the level and can also introduce an overdrive effect (as with real
analogue filters) if pushed hard. In Sidechain mode, only the left input signal is
processed and fed to both outputs. The envelope of the right input signal can be
used as a modulation source.
Rotary Speaker
Rotary Speaker emulates the sound of a Leslie rotating speaker. The Rotary
Speaker provides more flexibility than its electro-mechanical counterpart,
and can be used with a variety of instruments, and even vocals, to create a
whirling, psychedelic effect.
The LO SPEED and HI SPEED knobs adjust the rotational speed of the
SLOW and FAST Speed selection, and can be toggled with the FAST button.
The ACCEL(eration) knob adjusts how quickly the speed increases and
decreases from the Slow mode to the Fast mode. The rotation effect can also
be disengaged with the STOP button, which will stop the movement of the
speakers. DISTANCE adjusts the distance between the Rotary speakers and the
virtual microphone.
