Chapter 5. Creating Patches
Using Controllers to Change How 
Sounds Are Played (CONTROL)
The parameters in this group determine how various 
controllers will affect the Patch and its Tones.
PATCH KEY MODE 
(Patch Key Assign Mode)
fig.05-33
Assign (Key Assign)
Specifies whether the Patch will play polyphonically (POLY) 
or monophonically (MONO). The MONO setting is effective 
when playing a solo instrument Patch such as sax or flute.
POLY
: Two or more notes can be played simultaneously.
MONO
: Only the last-played note will sound.
Legato (Solo Legato Switch)
Solo Legato is valid when the Assign parameter is set to 
MONO. This setting specifies whether the Solo Legato 
function will be used (ON) or not (OFF).
When the Legato parameter is ON, pressing one key when 
another is already pressed causes the currently playing 
note’s pitch to change to that of the newly pressed key while 
continuing to sound. This can be effective when you wish to 
simulate performance techniques such as a guitarist’s 
hammering on and pulling off strings.
Legato Retrigger (Legato Retrigger Switch)
Legato Retrigger is enabled when the Assign parameter is set 
to MONO, and the Legato parameter to ON. The setting 
determines whether sounds are replayed (ON) or not (OFF) 
when performing legato. This is normally set to ON. When 
OFF, when one key is held down and another key is then 
pressed, only the pitch changes, without the attack of the 
latter key being played. Set this to OFF when performing 
wind and string phrases or when using modulation with the 
mono synth keyboard sound.
PATCH PORTAMNT (Patch Portamento)
fig.05-34
Sw (Portamento Switch)
Specifies whether the portamento effect will be applied (ON) 
or not (OFF).
When the Sw parameter is set to OFF, all of the following 
Portamento settings are disabled.
Time (Portamento Time)
When portamento is used, this specifies the time over which 
the pitch will change. Higher settings will cause the pitch 
change to the next note to take more time.
Mode (Portamento Mode)
Specifies the performance conditions for which portamento 
will be applied.
NORMAL
: Portamento will always be applied.
LEGATO
: Portamento will be applied only for notes played 
legato (i.e., when you press a second key before releasing the 
first.
Type (Portamento Type)
Specifies the type of portamento effect.
RATE
: The time it takes will depend on the distance between 
the two pitches.
TIME
: The time it takes will be constant, regardless of how 
far apart in pitch the notes are.
What is Portamento?
Portamento is a function that causes the Patch’s pitch to 
change smoothly from one note to the next note played. 
With the Assign parameter set to MONO, portamento is 
especially effective when simulating playing techniques 
such as a violin glissandos. Portamento can also be 
applied when Key Assign is polyphonic (POLY).
