In addition to the tuning method described on page 24, overall tuning can also be accom-
plished via the F1 function.
After selecting “F1”, use the [–/NO] and [+/YES] buttons to lower or raise the pitch in 
approximately 0.2 Hz increments (the first time the [–/NO] or [+/YES] button is pressed 
simply switches to the tuning value display without actually changing the tuning). The overall 
tuning range is from 427.0 Hz to 453.0 Hz (corresponding to the A3 note’s Hz). Press the [–/
NO] and [+/YES] buttons simultaneously to recall the default value “440.0 Hz”.
Tenths of a Hertz are indicated on the LED display by the appearance and position of one or 
two dots, as in the following example:
After selecting “F2.
Y”, press the [+/YES] button to engage the scale function sub-mode, 
then use the [TEMPO/FUNCTION# , ] buttons to select the desired scale function, as 
listed below. 
F2.1: Scale................................................................................................
In addition to the standard Equal Temperament tuning, the P-120/P-120S includes 6 classic 
tunings that you can select and use to play music of the corresponding period, or experiment 
with in a more modern context. The tunings are:
1: Equal Temperament 5: Mean Tone
2: Pure Major 6: Werckmeister
3: Pure Minor 7: Kirnberger
4: Pythagorean
Use the [–/NO] and [+/YES] buttons to select the number of the desired tuning.
 Press the [–/NO] and [+/YES] buttons simultaneously to recall the default settings 
(Equal Temperament tuning).
F2.2: Base Note.......................................................................................
Unlike Equal Temperament tuning, these classic tunings must be tuned to a specific key. 
Use the [–/NO] and [+/YES] buttons to select the key you want the previously selected 
tuning to be based. The selected key will appear on the display, followed by a low bar if flat 
(e.g. “A_”) or a high bar if sharp (e.g. “F~”).
Press the [–/NO] and [+/YES] buttons simultaneously to recall the default settings “C”.
• The base note setting is effective for tunings other than the Equal Temperament tuning.

F3.1: Dual Balance..................................................................................
The volume levels of the two voices combined in the dual mode can be adjusted as required 
by using this function. Use the [–/NO] and [+/YES] buttons to adjust the balance as 
required. The balance range is from 0 through 20. A setting of “10” produces equal balance 
between the two dual-mode voices. Settings below “10” increase the volume of the 2nd Voice 
in relation to the 1st Voice, and settings above “10” increase the volume of the 1st Voice in 
relation to the 2nd Voice (“1st” and “2nd” is explained on page 18). Press the [–/NO] and 
[+/YES] buttons simultaneously to recall the default setting (different for each voice combi-
nation).
You can set one voice as the main voice, and another voice as a softer, mixed voice.
F3.2: Dual Detune....................................................................................
This function makes it possible to detune the 1st and 2nd dual-mode Voices to create a 
thicker sound. Use the [–/NO] and [+/YES] buttons to set the amount of detuning as 
required. The detune range is from –10 through 10. A setting of “0” sets both voices to the 
same pitch. Settings below “0” increase the pitch of the 2nd Voice in relation to the 1st Voice, 
and settings above “0” increase the pitch of the 1st Voice in relation to the 2nd Voice (“1st” 
and “2nd” is explained on page 18). Press the [–/NO] and [+/YES] buttons simulta-
neously to recall the default setting (different for each voice combination).
F3.3: 1st Voice Octave Shift....................................................................
F3.4: 2nd Voice Octave Shift...................................................................
Depending on which voices you combine using the dual mode, the combination may sound 
better if one of the voices is shifted up or down an octave. Use the [–/NO] and [+/YES] 
buttons to set the octave of the 1st or 2nd Voice as required (“1st” and “2nd” is explained on 
page 18). The available settings are “0” for normal pitch, “–1” to shift the pitch down one 
octave, and “1” to shift the pitch up one octave. Press the [–/NO] and [+/YES] buttons 
simultaneously to recall the default setting (different for each voice combination).

F5.2: Sustain Sample Depth...................................................................
The GRAND PIANO 1 and 2 voices feature special “Sustain Samples” that recreate the 
unique resonance produced by an acoustic grand piano’s soundboard and strings when its 
damper pedal is pressed. The effect is can be controlled with the P-120/P-120S’s sustain pedal 
or the AUX PEDAL to which the sustain function has been assigned. This function lets you 
adjust the depth of this effect. The effect depth range is from 0 through 20. A setting of “0” 
produces no effect, while a setting of “20” produces maximum effect depth. Press the [–/
NO] and [+/YES] buttons simultaneously to recall the default setting of “12”.
F5: Pedal Functions ________________________________
1. Soft Pedal
The soft pedal reduces the volume and slightly 
changes the timbre of notes played while the 
pedal is pressed. The soft pedal will not affect 
notes which are already playing when it is 
pressed.
2. Sostenuto Pedal
If you play a note or chord on the keyboard and 
press the pedal while the note(s) are held, 
those notes will be sustained for as long as the 
pedal is held (as if the sustain pedal had been 
pressed) but all notes played thereafter will not 
be sustained. This makes it possible to sustain 
a chord, for example, while other notes are 
played “staccato.”
• Organ, string and choir voices will 
continue to sound for as long as the 
sostenuto pedal is depressed.
3. Expression
This mode allows control of dynamics during 
performance.
4. Sustain Pedal (ON/OFF)
The sustain pedal functions in the same way 
as the damper pedal on an acoustic piano. In 
this case the AUX PEDAL operates as an ON/
OFF switch so when the pedal is pressed, 
notes played have a long sustain. Releasing 
the pedal immediately stops (dampens) any 
sustained notes.
5. Sustain Pedal (Continuous)
The sustain pedal functions in the same basic 
way as the damper pedal on an acoustic piano 
however, in this case the pedal operates as 
continuous controller so the further down the 
pedal is pressed, the longer notes will sustain 
(can be used like a half pedal effect).
6. Variation
This mode allows switching of the Voice’s vari-
ation on or off. In this mode, the AUX PEDAL 
functions in the same manner as the [VARIA-
TION] button on the panel.
7. Song Start/Stop
This mode allows starting/stopping of song 
playback. In this mode, the AUX PEDAL func-
tions in the same manner as the SONG 
[START/STOP] button on the panel.
• We recommend that an optional foot 
controller FC7 be used with mode 3 
(Expression). In mode 5 (Sustain 
Pedal [Continuous]), we recommend 
that the supplied pedal be used. For 
all other modes, we recommend 
either the supplied pedal or the 
optional FC4 foot switch be used.

F5.3: Soft Pedal Effect Depth.................................................................
This function sets the depth of the soft pedal effect. The effect depth range is from 1 to 5. A 
setting of “1” produces minimum effect depth while a setting of “5” produces maximum effect 
depth. Press the [–/NO] and [+/YES] buttons simultaneously to recall the default setting 
of “3”.
F5.4: SUSTAIN PEDAL Type....................................................................
F5.5: AUX PEDAL Type............................................................................
Depending upon the pedal that is connected to the SUSTAIN PEDAL jack or AUX PEDAL 
jack, the effect produced by operating the pedal (ON/OFF, dynamics, etc.) might be reversed. 
If that is the case, use this setting to correct pedal operation. The setting range is from 1 to 2. 
Press the [–/NO] and [+/YES] buttons simultaneously to recall the default setting of “1”.
• Make sure that the power is switched OFF when connecting or disconnecting the pedal.
• If the SUSTAIN PEDAL type is set to “2”, disconnecting the sustain pedal while the power is switched 
on may leave the sustain active, causing notes to sustain indefinitely. In this case, switch the power 
“OFF” then back “ON”.
The volume of the metronome sound can be changed. After selecting “F6”, use the 
[–/NO] and [+/YES] buttons to set the metronome volume as required. The volume range 
is from 1 through 20. A setting of “1” produces minimum sound, while a setting of “20” pro-
duces maximum metronome volume. Press the [–/NO] and [+/YES] buttons simulta-
neously to recall the default setting “10”.
This function sets the volume at which a “canceled” part is played during preset song play-
back (see page 17 for information on the “preset song part cancel” function). Use the 
[–/NO] and [+/YES] buttons to set the volume as required. The volume range is from 0 
through 20. A setting of “0” produces no sound, while a setting of “20” produces maximum 
volume. Press the [–/NO] and [+/YES] buttons simultaneously to recall the default setting 
“5”.
Adjust the part volume to a comfortable level to use the “canceled” part as a guide to play 
along with. Set to “0” if you don’t want to hear the part.
 SHORTCUT:You can jump directly to the metronome functions by pressing the 
[TEMPO/FUNCTION#] button while holding the METRONOME [START/
STOP] button.

After selecting “F8.
Y”, press the [+/YES] button to engage the MIDI function sub-mode, then 
use the [TEMPO/FUNCTION# , ] buttons to select the desired MIDI function, as listed below. 
• The side-panel HOST SELECT switch must be set to “MIDI” in order to use the MIDI connectors. When you 
use the TO HOST connector, set the HOST SELECT switch to the appropriate position for the type of com-
puter you are using (see page 41). In this situation, all MIDI settings described below will have affect on the 
MIDI signal in and out of the TO HOST connector.
• Always use a high-quality MIDI cable to connect MIDI OUT to MIDI IN terminals. Never use MIDI cables 
longer than about 15 meters, since cables longer than this can pick up noise which can cause data errors.
F8.1: MIDI Transmit Channel Selection.........................................................
F8.2: MIDI Receive Channel Selection..........................................................
The MIDI system allows transmission and reception of MIDI data on 16 different channels. Mul-
tiple channels have been implemented to allow selective control of certain instruments or devices 
connected in series. For example, a single MIDI sequence recorder could be used to “play” two dif-
ferent instruments or tone generators. One of the instruments or tone generators could be set to 
receive only on channel 1, while the other is set to receive on channel 2. In this situation the first 
instrument or tone generator will respond only to channel-1 information transmitted by the sequence 
recorder, while the second instrument or tone generator will respond only to channel-2 information. 
This allows the sequence recorder to “play” two completely different parts on the receiving instru-
ments or tone generators.
F8: MIDI Functions _________________________________
 A Brief Introduction to MIDI
MIDI, the Musical Instrument Digital Interface, is a 
world-standard communication interface that allows MIDI-
compatible musical instruments and equipment to share 
musical information and control one another. This makes it 
possible to create “systems” of MIDI instruments and equipment that offer far greater versatility and control than is available 
with isolated instruments. For example, most MIDI keyboards (including the P-120/P-120S, of course) transmit note and veloc-
ity (touch response) information via the MIDI OUT connector whenever a note is played on the keyboard. If the MIDI OUT 
connector is connected to the MIDI IN connector of a second keyboard (synthesizer, etc.) or a tone generator (essentially a syn-
thesizer with no keyboard), the second keyboard or tone generator will respond precisely to notes played on the original trans-
mitting keyboard. The result is that you can effectively play two instruments at once, providing thick multi-instrument sounds.
This same type of musical information transfer is used for MIDI sequence recording. A sequence recorder can be used to 
“record” MIDI data received from a P-120/P-120S, for example. When the recorded data is played back, the P-120/P-120S auto-
matically “plays” the recorded performance in precise 
detail.
The examples given above really only scratch the sur-
face. MIDI can do much, much more. The P-120/P-120S 
MIDI functions allow it to be used in fairly sophisticated 
MIDI systems.

In any MIDI control setup, the MIDI channels of the transmitting and receiving equipment must 
be matched for proper data transfer. A “Multi-timbre” receive mode is also available, which allows 
simultaneous reception of different parts on all 16 MIDI channels, allowing the P-120/P-120S to 
play multi-channel song data received from a music computer or sequencer. There’s also a “1-2” 
mode which allows simultaneous reception on channels 1 and 2.
Use the [–/NO] and [+/YES] buttons to select the desired transmit or receive channel. The 
transmit channel parameter can also be turned “OFF” if you don’t want the P-120/P-120S to transmit 
any MIDI data. To select the multi-timbre receive mode, set the receive channel to “ALL”. Select “1-
2” for multi-timbre reception on channels 1 and 2 only.
Press the [–/NO] and [+/YES] buttons simultaneously to recall the default setting: transmit = 
“1”; receive = “ALL”.
• In the dual mode first voice data is transmitted on its set channel, and in the split mode right voice data is 
transmitted on its set channel. In the dual mode second voice data is transmitted on the next greater channel 
number of the set channel, and in the split mode left voice data is transmitted on the next greater channel 
number of the set channel. In either mode, no data is transmitted if the transmit channel is set to “OFF”.
• Demo/preset song data and recorder playback data are not transmitted via MIDI.
• No MIDI reception occurs when the demo/preset song mode is engaged.
• Program change and other like channel messages received will not affect the P-120/P-120S’s panel settings 
or what is being played on the keyboard.
F8.3: Local Control ON/OFF...........................................................................
“Local Control” refers to the fact that, normally, the P-120/P-120S keyboard controls its internal 
tone generator, allowing the internal voices to be played directly from the keyboard. This situation is 
“Local Control On” since the internal tone generator is controlled locally by its own keyboard.
Local control can be turned OFF, however, so that the P-120/P-120S keyboard does not play the 
internal voices, but the appropriate MIDI information is still transmitted via the MIDI OUT connec-
tor when notes are played on the keyboard. At the same time, the internal tone generator responds to 
MIDI information received via the MIDI IN connector.
Use the [–/NO] and [+/YES] buttons to turn local control “On” or “OFF”. 
Press [–/NO] and [+/YES] buttons simultaneously to recall the default setting “On”.
F8.4: Program Change ON/OFF.....................................................................
Normally the P-120/P-120S will respond to MIDI program change numbers received from an 
external keyboard or other MIDI device, causing the correspondingly numbered voice to be selected 
on the corresponding channel (the keyboard voice does not change). The P-120/P-120S will nor-
mally also send a MIDI program change number whenever one of its voices is selected, causing the 
correspondingly numbered voice or program to be selected on the external MIDI device if the device 
is set up to receive and respond to MIDI program change numbers.
This function makes it possible to cancel program change number reception and transmission so 
that voices can be selected on the P-120/P-120S without affecting the external MIDI device.
Use the [–/NO] and [+/YES] buttons to turn program change transmission and reception 
“On” or “OFF”. 
Press the [–/NO] and [+/YES] buttons simultaneously to recall the default setting “On”.
• For information on program change numbers for each of the P-120/P-120S’s voices, refer to page 51 in the 
MIDI Data Format section.

F8.5: Control Change ON/OFF.......................................................................
Normally the P-120/P-120S will respond to MIDI control change data received from an external 
MIDI device or keyboard, causing the voice on the corresponding channel to be affected by pedal 
and other “control” settings received from the controlling device (the keyboard voice is not affected). 
The P-120/P-120S also transmits MIDI control change information when the pedal or other appro-
priate controls are operated.
This function makes it possible to cancel control change data reception and transmission so that, 
for example, the P-120/P-120S’s pedal and other controls can be operated without affecting an exter-
nal MIDI device.
Use the [–/NO] and [+/YES] buttons to turn control change transmission and reception “On” 
or “OFF”. 
Press the [–/NO] and [+/YES] buttons simultaneously to recall the default setting “On”.
• For information on control changes that can be used with the P-120/P-120S, refer to the MIDI Data Format on 
page 50.
F8.6:  MIDI Transmit Transpose.......................................................................
This function allows the MIDI note data transmitted by the P-120/P-120S to be transposed up or 
down in semitone increments by up to plus or minus 12 semitones. The pitch of the P-120/P-120S 
itself is not affected.
Use the [–/NO] and [+/YES] buttons to set the desired amount of MIDI transmit transposi-
tion. The range is from “–12” (down one octave) through “0” (no transposition) to “12” (up one 
octave). 
Press the [–/NO] and [+/YES] buttons simultaneously to recall the default setting “0”.
F8.7: Panel/Status Transmit............................................................................
This function causes all the current P-120/P-120S panel settings (selected voice, etc.) to be trans-
mitted via the MIDI OUT terminal. This is particularly useful if you will be recording performances 
to a MIDI sequence recorder such as the Yamaha MIDI Data Filer MDF3 which will be used to con-
trol the P-120/P-120S on playback. By transmitting the P-120/P-120S panel settings and recording 
them on the MIDI sequence recorder prior to the actual performance data, the P-120/P-120S will be 
automatically restored to the same settings when the performance is played back. 
Press the [+/YES] button to transmit the panel/status data. “End” will appear on the LED dis-
play when the data has been successfully transmitted.
• See page 51 for list of the “Panel Data Contents” transmitted by this function.
• Panel setting data that is transmitted to an external device can only be reloaded on another P-120/P-120S. 
Panel setting data can also be directly transferred to or from another P-120/P-120S.
F8.8: Bulk Data Dump.....................................................................................
This function is used to transmit all data stored in the User Song Recorder memory to a MIDI data
