Portamento

Portamento causes the pitch of a note to glide up or down from the pitch

of the previously played note. Portamento is turned on and off using

the

portamento switch, but the rate must also be set. If the portamento

button is on, but

rate amount is set to 0, portamento has no effect.

RATE PORTAMENTO

The Portamento controls

There are four modes that determine how portamento behaves.

Fixed Rate (FR): The time to transition between notes varies with the

interval between the notes; the greater the interval, the longer the transi-

tion time. The portamento rate is xed. This is the default portamento

mode.

Fixed Rate A (FRA): The same as Fixed Rate, but portamento is only

applied when playing legato. That is, portamento only occurs when a

note is held until the next note is played. This effectively allows porta-

mento to be turned on and off from the keyboard.

Fixed Time (FT): Portamento is set to a xed time, regardless of the

interval between notes.

Fixed Time A (FTA): The same as Fixed Time, but portamento only

occurs when playing legato.

To select a portamento mode:

1. Press and hold the portamento switch. The numeric display shows the

currently selected portamento mode.

2. To select a different mode, continue to hold down the portamento

switch then press the bank/decrement and tens/increment switches to

step through the other choices.

3. When nished, release the portamento switch.
