Using Other Functions
About the confirmation sound
When# you press and hold down the A 7, B7, and C8 keys simul- taneously at the right end of the keyboard, or you press a key where a function has been assigned, you will hear the confir- mation sound. You can turn this sound off, as described below.
While simultaneously #pressing and holding down the A 7, B7, and C8 keys, press the A#0 to turn off the confirmation sound. To turn on the confirmation sound, repeat the previous procedure# but press the B0 instead of A 0.
The default setting (when you turn on the unit) is "Confirmation sound On.”
In addition to selecting a preset sound or demo song, the SP-170 enables you to use various functions by pressing and holding down the A#7, B7, and C8 keys and pressing a key to where the corresponding function has been assigned. Please refer to the “MIDI” section on the next page for more information on MIDI channels and program change messages.
While pressing and holding down the A#7, B7, and C8 keys, do not play the key- board. Otherwise, you might get an unexpected result.
Effects (Reverb and Chorus)
You can use a reverb effect to add reverberation and depth to the sound, and a chorus effect to add width and space.
•While simultaneously pressing and holding down the A#7, B7, and C8 keys, press
the A5 key to turn on the reverb effect. To turn off the reverb effect, repeat the pre- vious procedure but press the C#5 key instead of A5.
•While simultaneously pressing and holding down the A#7, B7, and C8 keys, press
the B5 key to turn on the chorus effect. To turn off the chorus effect, repeat the previous procedure but press the A#5 key instead of B5.
You can apply effects to each preset sound. When you turn on the power to the unit, the effects will use the optimum settings for each preset sound.

Key Touch Control function
The Key Touch Control function enables you to change the way your playing strength affects the sound output level. You can set this function using the white keys in a range from D2 to F2. (See the figure on the left.)
•To play fortissimo with soft strokes (Light touch), press and hold down the A#7, B7, and C8 keys (at the right end of the keyboard), and press the D2 key.
•To play fortissimo with very strong strokes (Heavy touch), press and hold down the A#7, B7, and C8 keys, and press the F2 key.
•To simulate a normal piano touch (Standard touch), press and hold down the A#7, B7, and C8 keys, and press the E2 key.
The default setting (when you turn on the unit) is Standard touch.
F3 key
+5 semitones. Playing the C3 key will sound the F3 pitch.
C3 key
0. Normal state.
F#2 key
-6 semitones. Playing# the C3 key will sound the F 2 pitch.
Transpose function (Shifting the key)
In some cases, a song may be written in a difficult key (e.g., using many black keys), or you may wish to shift the key to match another instrument or vocalist. In such cases, you can transpose (shift the key) to use an easier fingering (without playing too many black keys), or to use the same familiar fingering to play in a different key. This is called the Transpose function. You can shift the key in a range of eleven semitones.
For example if you transpose upward by one semitone, playing the notes shown in the upper score to the left will produce the pitches shown in the lower score.
•To transpose the key, press and hold down the A#7, B7, and C8 keys, and press a key from F#2 to B3 or from C#3 to F3. The name of the key that you pressed will become
the transposed key. For example, if you wish to use the C3 key to play note A2 (lower by three semitones), press and hold down the A#7, B7, and C8 keys, and press the A2 key. If you wish to use the C3 key to play note D#3 (higher by three semitones), press and hold down the A#7, B7, and C8 keys, and press the D#3 key.
To reset the Transpose function to “No Transposition (+/-0),” press and hold down the A#7, B7, and C8 keys, and press the C3 key.
The default setting (when you turn on the unit) is “No Transposition.”

Here's how to make fine adjust- ments to the pitch.
When you're playing together with other instruments, you can use this method to fix any slight differences in pitch between in- struments.
Pitch Control function (Tuning)
You can adjust the tuning of the SP-170 in half-step (0.5) Hz intervals over a range of 427.5 - 452.5 Hz (Hertz) by using the E5 and F5 keys.
•While pressing and holding down the A#7, B7, and C8 keys (on the right end of the keyboard), press the E5 key repeatedly to lower the pitch in 0.5Hz steps, or the F5 key repeatedly to raise the pitch in 0.5Hz steps.
•To reset the pitch to 440Hz, press and hold down the A#7, B7, and C8 keys, and press the E5 and F5 keys simultaneously.
The default setting (when you turn on the unit) is A4=440Hz.
MIDI
Using the MIDI OUT jack
The MIDI OUT jack transmits MIDI messages. When you play the keyboard, the MIDI messages will be output to control (e.g, play the sound of) an external MIDI device. Use an optional MIDI cable to connect the MIDI OUT jack of the SP-170 to the MIDI IN jack of an external MIDI device.

Changing the MIDI channel
If you're using the SP-170 as a controller to play the sound from a connected MIDI de- vice, the MIDI channel of the SP-170 must match that of the external MIDI device.
To change the MIDI channel (1-16) that MIDI data is being transmitted from via the MIDI OUT jack on the rear panel, press and hold down the A#7, B7, and C8 keys simul- taneously, and press one of the keys ranging from C4 to D#5. The default MIDI channel (when you turn on the unit) is “1.”
Transmitting Program Change and Control Change messages
You can change the program number of the connected MIDI device from the SP-170. When you select a preset sound on the SP-170 (see “Playing Different Sounds” on page 4), it transmits a MIDI Program Change number (PC#) as shown in the table on the left. To disable this transmission (DIS), press and hold down the A#7, B7, and C8 keys simulta- neously, and press the G#3 key. To enable this transmission (ENA), repeat the previous procedure but press the A3 key instead.
The SP-170 also transmits Control Change messages to control Damper (CC64), Bank Se- lect (CC64), etc. of the connected MIDI device. To disable this transmission (DIS), press and hold down the A#7, B7, and C8 keys simultaneously, and press the A#3 key. To enable this transmission (ENA), repeat the previous procedure but press the B3 key instead.
The default setting (when you turn on the unit) is ENA (transmitted) for both Program and Control Change messages.

Troubleshooting
|
If you suspect any malfunction, check the following suggestions. If the problem per- |
|
sists, contact your nearest Korg distributor. |
Power does not turn on |
· Make sure that the AC adapter is properly connected to the SP-170 and the AC outlet. |
|
· Make sure that the power switch on the rear panel is set to ON. |
No sound from the speakers |
· Rotate the [VOLUME] knob on the rear panel toward MAX. |
|
· The speakers will be muted if the headphones are connected. |
Sound is interrupted |
· The preset sounds of the SP-170 have been created by sampling (recording) the |
|
sounds of actual instruments, then analyzing and processing the samples. When |
|
you press a key, some sounds play a single piece of sampled data, while other |
|
sounds play two pieces of sampled data. The SP-170 uses two pieces of data for most |
|
of its preset sounds. When one of these two-sample sounds is selected (regardless of |
|
whether the damper pedal is being pressed), the maximum polyphony is 60 notes. |
|
However, with two Piano sounds, the maximum polyphony is 120 notes. If the maxi- |
|
mum polyphony is exceeded, some of the notes will be lost. |
The pitch or tone of the piano sounds wrong in some key regions
·The SP-170’s piano sounds replicate the sound of an actual piano as faithfully as pos- sible. This means that in some regions of the keyboard, you may feel that the over- tones seem stronger, or that the tone or pitch seems wrong. This is not a malfunction.
Pedal is not effective · Make sure that the pedal cable is properly connected.
Connected MIDI device does not respond to MIDI messages
·Make sure that all MIDI cables are properly connected.
·Make sure that the SP-170 is transmitting MIDI data on the same MIDI channel as that of the connected MIDI device.
