SP2 Performance Features
Rear Panel
MIDI Ports
Use the MIDI Out and MIDI Thru ports to connect to an external sound module such as
Kurzweil K2600R or PC2R. Use the MIDI In port when you are using the SP2 as a sound module
for a sequencer application or another MIDI controller. See "Connecting MIDI" on page 2‐4 for
more information.
USB Port
Use the USB port to connect to a computer. When the SP2 is connected to a computer via USB
cable, it can transmit and receive MIDI data without using MIDI In and Out ports. See
Connecting to a Computer via USB" on page 2‐7 for more information.
The USB port of the SP2 carries only MIDI data, not audio data.
( Universal Serial Bus ) is a serial bus standard to interface devices.
Pedal Jacks
Continuous Control ( CC ) Pedal Jack
You can plug a control pedal in here. A control pedal is very useful when controlling volume,
expression, vibrato, and more MIDI effects with your foot. You can use a Kurzweil CC‐1 pedal
of course, or just use a third‐party control pedal for generic synthesizers. With some pedals, you
may not be able to get the results that you want according to your control pedal setting. If you
need more detailed information about control pedal or having problems making it work
properly, see "Control Pedal Problems" on page 9‐4.
Switch ( SW ) Pedal Jack
Use this jack to plug in a switch pedal. You can plug the single piano pedal that came with your
SP2 here. By default, it will perform a sustain ( or damper ) function. Of course, you can use
Kurzweil KP‐1, KP‐2 or KP‐3 too.
Kurzweil keyboards determine the polarity of the pedal when it is turned on.
If your switch pedal works backwards, you can reverse the polarity by pushing it
while turning on your instrument.
