Yamaha MOTIF XS8 User Manual

Some preset Arpeggio types include the special sequence 
data called “Accent Phrase,” which will be played back 
only when the velocities higher than a specified value are 
received. This parameter determined the minimum velocity 
that will trigger the Accent Phrase. 

Settings: off, 1 – 127

Determines the start timing of the Accent Phrase when the 
Velocity specified in Accent Vel Threshold above is 
received. When set to off, the Accent Phrase starts as soon 
as the Velocity is received. When set to on, the Accent 
Phrase starts on the beat specified for each Arpeggio type 
after the Velocity is received. 

Settings: off, on

Some Arpeggio types feature the Random SFX function 
which will trigger the special sound such as fret noise of 
the guitar when the note is released. This parameter 
determines whether the Random SFX is active or not. 

Settings: off, on

Determines the offset value by which the Random SFX 
notes will be shifted from their original velocities. If the 
resultant velocity value is less than zero it will be set to 1, 
and if the resultant velocity is greater than 128 it will be set 
to 127. 

Settings: -64 – +0 – +63

When this is set to “on,” the Random SFX special sound is 
played with the pre-programmed velocity. When this is set 
to “off,” the Random SFX special sound is played with the 
velocity generated when the note is pressed. 

Settings: off, on

When this is set to on, Arpeggio playback data is output 
from the MIDI terminal. 

Settings: off (not output), on (output)

Determines the MIDI transmit channel for Arpeggio 
playback data. When this is set to “kbd,” Arpeggio 
playback data is output via the MIDI transmit channel 
(page 137) set in the Performance Play mode. 

Settings: 1 – 16, kbd (Keyboard Channel)

You can control the sound transition from the moment a key 
is pressed to the moment at which it is released. You can 
also adjust the tone brilliance by setting the Cutoff 
Frequency and Resonance. 

Determines the AEG (Amplitude Envelope Generator) 
parameters for each Part. The following parameters can be 
used to control the change in volume from the moment a 
note is pressed on the keyboard to the moment the sound 
stops. The setting made here will be applied to the AEG 
parameters (page 123) of each Voice as offset. 

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. 

Release (Release Time)

Determines how quickly the sound decays to silence after the 
key is released. 

Settings: -64 – +0 – +63

n When a Drum Voice is selected, Sustain Level and 

Release Time are not available. 

Determines the FEG (Filter Envelope Generator) 
parameters for each Part. Using the FEG, you can control 
the transition in tonal color (Cutoff Frequency) from the 
moment the sound starts to the moment it stops. The 
setting made here will be applied to the FEG parameters 
(page 119) of each Voice as offset. 

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.
