Yamaha MOTIF XS7 Manuel D’Utilisation

Follow the instructions below to apply the Portamento to 
the current Voice you play on the keyboard. 

Select a Voice to which the Portamento is applied. The 
Portamento is effective especially for a Voice that 
sustains or continues to sound while the key is being 
held down. 

For best results, set this to a relatively high value. 

It is a good idea to press a certain note then press the 
one octave higher or lower note for confirming how the 
Portamento is applied. 

You can change the tonal color or timbre of the sound by 
editing the EG/EQ settings for all Elements making up the 
Voice. The EG settings made here will be applied to the 
same parameters in the Amplitude EG display (page 123) 
and Filter EG display (page 119) for all Elements as an 
offset. In other words, editing the value here will add to or 
subtract from the current value. Accordingly, if the 
parameter has been already set to the maximum or 
minimum value, its value will not be changed even if you 
set the parameter to higher or lower value in this display. 
Note that the EQ settings here are applied to the Voice 
directly. 

Using the AEG, you can control the transition in volume 
from the moment the sound starts is to the moment the 
sound stops. 

Attack (Attack Time)

Determines the speed of attack from the time a key is played 
until the maximum initial level of the EG is reached. 

Decay (Decay Time)

Determines how fast the volume falls from maximum attack 
level to the sustain level. 

Sustain (Sustain Level)

Determines the sustain level at which the volume will continue 
while a note is held, after the initial attack and decay. The 
smaller the value, the sharper the sound.

Release (Release Time)

Determines how fast the volume falls from the sustain level to 
zero when a note is released. 

Settings: -64 – +0 – +63
n When a Drum Voice is selected, the Sustain Level and 

Release Time are not available. “---” appears at each of 

the corresponding columns and these parameters cannot 

be edited. 

Using the FEG, you can control the transition in tonal color 
(Cutoff Frequency) from the moment the sound starts to the 
moment the sound stops. Actual transition of tonal color 
differs depending on the Filter type (page 117) of the Voice 
Element. 

Attack (Attack Time)

Determines the speed of filter variation from the time a note is 
played until the maximum initial level of the Cutoff Frequency 
is reached. 

Decay (Decay Time)

Determines how fast the Cutoff Frequency falls from maximum 
attack level to the sustain level. 

Release (Release Time)

Determines how fast the Cutoff Frequency falls from the 
sustain level to zero when a note is released. 

Depth

Determines the range over which the cutoff frequency of the 
Filter EG changes. A setting of 0 will result in no change in the 
cutoff frequency. The farther from 0 the value is, the larger the 
range of the cutoff frequency. For negative values, the change 
of the cutoff frequency is reversed. 

Settings: -64 – +0 – +63

This unit modifies the tonal color of the sound by cutting 
the output of a specific frequency portion of the sound. 
Actual tonal color differs depending on the Filter type 
(page 117) of the Voice Element. The Low Pass Filter cuts 
the signals above the Cutoff Frequency while the High 
Pass Filter cuts the signals below the Cutoff Frequency. 

Cutoff

Determines the Cutoff Frequency for the Filter, when the Low 
Pass Filter is selected, for example, the larger the value the 
brighter the decay.
