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 seing (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 transmied 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 Dierent Sounds” on page 4),
it transmits a MIDI Program Change number (PC#) as shown in the table on the le. 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 seing (when you turn on the unit) is ENA (transmied) for both Program
and Control Change messages.
