Connecting a Switch Pedal

When plugged into the FOOTSW jack on the rear-panel, a single switch pedal will, by

default, act like a sustain pedal. Of course this can be changed by programming, as described

in Setup Mode on page 7-1.

If you use a third-party (non-Kurzweil) switch pedal, make sure it’s connected before you

turn on your SP4. This ensures that the pedal will work properly (it might function in

reverse—off when it’s down and on when it’s up—if you turn on your SP4 before plugging

in the pedal). Similarly, don’t press any of your switch pedals while powering up, as the SP4

veriﬁes each pedal’s orientation during power up—if you’re pressing a pedal, you might

cause it to work in reverse.

See Switch Pedal Problems on page 12-5 if you are having trouble with your switch pedal.

Connecting Dual Switch Pedals

The jack will also accept a dual switch pedal having a single stereo plug. The plug should be

wired so that the left pedal connects to the ring contact and the right pedal to the tip contact.

It’s also possible to use two single pedals with this jack: ﬁrst buy a 1/4-inch stereo-to-dual-

mono Y adapter (this will have two mono 1/4-inch phone jacks and a stereo 1/4-inch plug);

then, plug the pedal you wish to use for sustain into the left jack and your sostenuto pedal

into the right jack. Note that the “left” pedal goes into the right jack and vice-versa.

By default, the right pedal will control sustain as before and the left pedal will control the

sostenuto function. If you’re not familiar with traditional piano technique, the sostenuto

(center) pedal on a grand piano allows one to hold chords in the bass while continuing

to play the melody without the latter notes sustaining. Any keys that are down when you

depress the pedal will sustain when you let go of the keys, but new notes played afterward

will not be sustained. Releasing the pedal puts things back to normal. Of course it can be

programmed to do other functions as well.

Connecting a Control Pedal

A control pedal can be very useful for controlling volume, vibrato, or other effect by foot.

The Kurzweil CC-1 control pedal will work best with the SP4, but it is also possible to use

third-party control pedals designed for synthesizers. Note that a volume pedal may or may

not be satisfactory depending on how it is constructed.

See Control Pedal Problems on page 12-6 if you are having trouble with your control pedal.
