The Effects
36
RATE - Controls the frequency of the Low Frequency Oscillator (LFO). Use low settings with
higher depths for slow moving sounds. Increase the rate for vibrato effects. Set fully CCW to sync
the LFO to the Global LFO1 oscillator.
DEPTH - Sets the maximum delay variation. Higher depths increase the amount of detuning.
Usually the rate and depth settings should be varied inversely, i.e. if you increase the rate decrease
the depth however some unique sounds can be obtained using high rates and depths.
MIX - Sets the ratio of wet and dry. Duplicated from MIX page. A setting of 50% produces the most
prominent effect. Try setting the mix to 100% for vibrato effects.
TEMPO - Locks the rate to the global tempo. For example, if the global tempo is 120 bpm and the
tempo is set to a quarter note (1/4) then the LFO rate will be 2 Hz (120 bpm / 60 seconds = 2). To
ignore the global tempo set the tempo control to
NONE.
Advanced Parameters
BASS - Adjusts the bass response of the wet signal. The bass can be boost or cut up to 12 dB.
TREBLE - Adjusts the treble response of the wet signal. The treble can be boost or cut up to 12 dB.
BASS FREQ - Adjusts the corner frequency of the bass control.
TREBLE FREQ - Adjusts the corner frequency of the treble control.
DELAY TIME - Adjusts the minimum delay time of the delay line. This can provide subtle changes
in the character of the effect.
LFO PHASE - Adjusts the phase difference between the left and right lfo waveforms. For
maximum stereo spread set this to 180 degrees. For a mono chorus simply set this to zero.
LFO TYPE - Selects between the various waveforms for the LFO. Sine is the most commonly used
waveform. NOTE: only the sine type is allowed for more than two voices. If the number of voices
is set to more than two the LFO type will be reset to sine. If the number of voices is greater than two
and the LFO type is changed to something other than sine the number of voices will be reset to two.
For different chorus effects try experimenting with the type parameter. The Trapezoid waveform is
of particular interest as it was used in a classic “Dimension” chorus processor. Set the LFO Phase
to 90 degrees to duplicate the sound of this particular processor.
AUTO DEPTH -
When this is set to
LOW
or
HIGH
the depth is automatically scaled for the rate.
Lower rates therefore increase the actual depth and vice-versa. The
HIGH
setting allows greater
maximum depth. This greatly simplifies adjusting the rate and depth and gives the most musical
results. For wild sounds you may wish to set this to
OFF
which decouples the controls allowing for
full depth swing even at fast rates.
PHASE REVERSE -
When this is set to
ON
the phase of the right channel is reversed on the effected
signal. This increases the stereo imaging.
