1 Center Pedal, 2 Left Pedal
These allow you to select the function to be assigned to the center or left pedal of the pedal unit (sold
separately) connected to the [PEDAL UNIT] jack.
3 Modulation
When a pedal function is set to Modulation ( page 77 ), the pedal can be used to modulate the parameters
below as well as the pitch (vibrato). Here, you can set the degree to which the pedal modulates each of the
following parameters.

Portamento
Time
Determines the pitch transition time when the edited Voice is set to
Mono
above.
NOTE
Portamento is a function that creates a smooth transition in pitch from the first note played on the
keyboard to the next.

Portamento Type Determines how an actual pitch transition time is calculated from the Por-
tamento Time value above.
• Fixed Rate : Make the pitch change rate to 0: max., 127: min. The actual
pitch transition time varies according to the interval between the two
notes.
• Fixed Time : Make the actual pitch transition time to 0: min., 127: max.
The pitch change rate varies according to the interval between the two
notes.
NOTE
The basic rule of Portamento Time is unchanged even if this setting is changed. When the value of
Portamento Time is smaller, the actual time is shorter; when the value is larger, the actual time is
longer.
NOTE
The greater the value of Portamento Time, the clearer the effect of this setting will be.
