VCM is a technology that authentically models the elements in
analog circuitry (such as resistors and capacitors). Effect types
using the VCM technology produce the uniquely warm
characteristics of vintage processing gear.
VCM Compressor 376
This effect emulates the characteristics of analog compressors,
used as standard effects in recording studios. It frames and
thickens the sound, and is suitable for drum and bass sounds.
VCM Equalizer 501
This effect emulates the characteristics of analog equalizers
used in 1970s. It adds drive to the sound by reproducing
distortion typical of analog circuits. It consists of two shelving-
type filters and three peaking-type filters.
VCM Flanger
This effect emulates the characteristics of analog flanger used in
the 1970s, recreating a warm, high-quality flanger effect.
VCM Phaser Mono, VCM Phaser Stereo
These effect emulate 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-RACK XS features two types of REV-
X effects: REV-X Hall and REV-X Room.
Effect Parameters
Each of the Effect Types has parameters that determine 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 by the “Preset” parameter 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. For details
about the preset settings of each effect type, refer to the
separate Data List booklet.
Effect Parameters making up the affect of the Effect Type are
listed here in alphabetical order.
n Each name of the parameters listed below is indicated with its full or
complete spelling, although it is indicated with the abbreviated spelling on
the LCD. The discrepancy in the name may make it difficult to find the
desired parameter. In such a case, confirm the parameters belonging to
the Effect Type you want to edit by referring to the Effect Parameter List in
the separate Data List booklet.
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.

Effect parameters
Parameter name Description
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 Determines the wave of the amplitude modulation.
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.
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 When the Reverb effect is selected, this determines the
density of the reverberations.
When the Early Reflection is selected, this determines the
density of the 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 the 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.
