VCM Flanger
These effects emulate the characteristics of analog flanger
used in the 1970s, recreating a warm, high-quality flanger
effect.
VCM Phaser Mono, VCM Phaser Stereo
This effect emulates the characteristics of analog phasers
used in the 1970s, recreating a warm, high-quality phaser
effect.
VCM Auto Wah, VCM Touch Wah, VCM Pedal
Wah
These effects emulate the characteristics of analog Wah
used in the 1970s, recreating a warm, high-quality wah-
wah effect.
REV-X is a reverb algorithm developed by Yamaha. It
provides a high-density, richly reverberant sound quality,
with smooth attenuation, spread and depth that work
together to enhance the original sound.
The MOTIF XF features two types of REV-X effects: REV-X
Hall and REV-X Room.
Effect Parameters
Each of the Effect Types has parameters determining how
the Effect is applied to the sound. A variety of sounds can
be obtained from a single effect type by setting these
parameters. For information about the Effect parameters,
see below.
Preset settings for parameters of each effect type are
provided as templates and can be selected in the Effect
Type selection display. To get a desired effect sound, try
first selecting one of the Presets close to your imagined
sound, then change the parameters as necessary.
n
Some parameters below may appear in different effect types
with the same name, but actually have different functions
depending on the particular effect type. For these parameters,
two or three types of explanations are given.

Parameter name
Descriptions
AEG Phase
Offsets the phase of the AEG.
AM Depth
Determines the depth of the amplitude modulation.
AM Inverse R
Determines the phase of the amplitude modulation for the R
channel.
AM Speed
Determines the amplitude modulation speed.
AM Wave
Selects the wave for modulating the amplitude.
AMP Type
Selects the amplifier type to be simulated.
Analog Feel
Adds the characteristics of an analog flanger to the sound.
Attack
Determines the amount of time that elapses between the playing
of a key and the start of the compressor effect.
Attack Offset
Determines the amount of time that elapses between the playing
of a key and the start of the wah effect.
Attack Time
Determines the attack time of the envelope follower.
Bit Assign
Determines how the Word Length is applied to the sound.
Bottom
*1
Determines the minimum value of the wah filter.
BPF1–10 Gain
Determines each output gain of BPFs 1 – 10 of the Vocoder
effect.
Click Density
Determines the frequency at which the click sounds.
Click Level
Determines the click level.
Color
*2
Determines the fixed phase modulation.
Common Release
This is a parameter of “Multi Band Comp.” This parameter
determines the amount of time that elapses between the
releasing of a note and the end of the effect.
Compress
Determines the minimum input level at which the compressor
effect is applied.
Control Type
This is a parameter of “Control Delay.” When set to “Normal,” the
delay effect is always applied to the sound. When set to
“Scratch,” the delay effect is not applied if both the Delay Time
and Delay Time Offset are set to “0.”
Damper Control
When the half-damper compatible FC3 footswitch is connected
to the SUSTAIN jack, the Damper Control parameter is controlled
by the FC3 over a range of 0 – 127, allowing for partial damper
effects, such as is available on an actual grand piano.
Decay
Controls how the reverb sound decays.
Delay Level C
Determines the level of the delayed sound for the center channel.
Delay Mix
Determines the level of the delayed mixed sound when multiple
effects are applied.
Delay Offset
Determines the offset value of the delay modulation.
Delay Time
Determines the delay of the sound in note value or absolute time.
Delay Time C, L, R
Determines the delay time for each channel: center, left and right.
Delay Time L>R
Determines the amount of time between the moment the sound is
input from the L channel and the moment the sound is output to
the R channel.
Delay Time Ofst R
Determines the delay time for the R channel as offset.
Delay Time R>L
Determines the amount of time between the moment the sound is
input from the R channel and the moment the sound is output to
the L channel.
Delay Transition
Rate
Determines the speed (rate) at which the delay time is changed
from the current value to the specified new value.
Density
Determines the density of the reverberations or reflections.
Depth
When “Space Simulator” is selected, this parameter determines
the depth of the simulated room.
When “VCM Flanger” is selected, this parameter determines the
amplitude of the LFO wave which controls the cyclic change of
the delay modulation.
When “Phaser Type” is selected, this parameter determines the
amplitude of the LFO wave which controls the cyclic change of
the phase modulation.
Detune
Determines the amount of pitch to be detuned.
Device
Selects the device for changing how to distort the sound.
Diffusion
Determines the spread of the selected effect.
Direction
Determines the direction of the modulation controlled by the
envelope follower.
Divide Freq High
Determines the high frequency for dividing the entire sound into
three bands.
Divide Freq Low
Determines the low frequency for dividing the entire sound into
three bands.
Divide Min Level
Determines the minimum level of the portions extracted via the
slice effect.
Divide Type
Determines how the sound (wave) is sliced by the note length.
Drive
When one of the distortion, noisy and slice effects is selected,
this parameter determines the extent to which the sound is
distorted.
When one of the misc effects is selected, this parameter
determines the extent to which the enhancer or talking modulator
is applied.
