Playing the Keyboard in the Voice Play Mode
MOTIF XS Owner’s Manual

Follow the instructions below to apply the Portamento to
the current Voice you play on the keyboard.
1 Press the [VOICE] button to enter the Voice
Play mode.
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.
2 Press the [F2] button to call up the Portamento
display.
3 Set the Portamento Switch to on.
4 Set the Portamento Time.
For best results, set this to a relatively high value.
5 Play two different keys alternatively to confirm
the Portamento.
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.
Changing tonal color—[F3] EG/EQ
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.
1 AEG (Amplitude EG)
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.
2 FEG (Filter EG)
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.
