Performance file
A performance file consists of a group of 32 performances.
The P-250 features one special performance file that consists of unique preset performances. It is called the “preset perfor-
mance file.” You can edit any performance in the preset performance file to create a new performance, and store the edited 
performance file in memory (as described later). For more information on using the performance file, see “Handling Perfor-
mance Files [PERFORM.FILE]” (page 42).
A performance file stored in memory can be controlled from a connected computer. For more information on connecting a 
computer, see “Connecting to a Personal Computer” (page 19).

■Songs
The P-250 enables you to record and play back your keyboard performance, as well as to recall and play 
back the internal demo songs. The P-250 features sixteen recording tracks, which enable you to record 
different parts on different tracks or play only the selected tracks.
See “Song Operation” (page 46) for more information on using songs.
Song file
A song can be stored as a song file in memory (as described later). See “Song Playback” (page 51) for information on song 
files.
You can import a P-250 song file into a connected computer (page 19). The imported song file is in the “SMF format 0.” You 
can also import song data as a song file from a computer into the P-250 for playback. Refer to “Connecting to a Personal 
Computer” (page 19) for information on connecting the P-250 to a computer.
The following song data can be played on the P-250:
•Sequence Format

Refer to “Data compatibility” on page 88 for more information on formats.
■About P-250 Memory
Storage memory
Storage memory is an area in memory that stores performance files and multiple song files. The performance files and song 
files in storage memory are not erased when the power to the P-250 is turned off. The memory size is approximately 1.5 MB.
Current memory
Current memory is a memory area that contains the currently-selected performance files and song file. You can recall a per-
formance in the performance file in current memory from the top panel. A song in current memory is recorded or played 
back.
 CAUTION
The content of current memory is erased when the power is 
turned off.

							P-25037
Basic Operation
Basic Operation■Effect Structure
The P-250 features system effects and inser-
tion effects.
System effects
The system effects are applied to all parts globally. 
The amount of effect can be set per part. The P-
250 system effects include one reverb and one 
chorus. The amount of reverb and chorus is set via 
the “ReverbSend” (page 66) and “ChorusSend” 
(page 67) parameters in the “VOICE EDIT” menu.
•Reverb
Reverb can add a natural ambience and space to a 
sound, simulating the natural reverberation of a con-
cert hall or live venue.
Refer to the “XG Effect Type list” on page 12 of the 
separate “Data List” for a complete list of reverb types 
included in the P-250.
•Chorus
Chorus adds spread and spaciousness, and is an effect 
that modifies the sound of a single instrument to simu-
late a group of the same instrument.
Refer to the “XG Effect Type list” on page 12 of the 
separate “Data List” for a complete list of chorus types 
included in the P-250.
Insertion effects
Insertion effects are applied to specified parts. The 
P-250 features three insertion effect channels, 
which means that you can apply the insertion 
effects to three parts.
The amount of insertion effect is adjusted via the 
“Dry/WetBalance” parameter (page 68) in the 
“VOICE EDIT” menu.
■Using the Effects
Reverb
Press the [REVERB] button repeatedly to toggle 
the reverb on and off.
When the reverb is turned on, the indicator above 
the [REVERB] button lights up.
Even if the reverb effect is turned off, a “soundboard 
reverb” effect is applied when you select the GRAND 
PIANO1 or GRAND PIANO2 voice group.
Reverb On/Off is a performance parameter (page 
30).
Chorus
Press the [CHORUS] button repeatedly to toggle 
the chorus on and off.
When the chorus is turned on, the indicator 
above the [CHORUS] button lights up.
You can turn the chorus effect on or off by pressing the 
[CHORUS] buttons on the panel or by setting the 
“ChorusOnOff” parameter in the “VOICE EDIT” menu 
(see page 67). The [CHORUS] button setting on the 
panel is cancelled if you select another voice. The 
“ChorusOnOff” parameter setting is saved for each 
voice. That is, if you select a voice, the chorus setting 
is automatically turned on or off, depending on the 
saved chorus setting.

							Basic Operation
38   P-250
Basic Operation
■Using the Master Equalizer
The five-band (LOW, LO-MID, MID, HI-MID, 
HIGH) Master Equalizer enables you to adjust 
the sound quality.
For example, you can enhance the high range 
of the P-250 sound so that it will stand out 
from an ensemble. Or, you can boost the lower 
range to create a dynamic sound. Use the mas-
ter equalizer to suit the situation or to produce 
a desired tonal color.
Raise or lower the MASTER EQUALIZER slid-
ers to boost or cut the corresponding fre-
quency band.
All parameters accessed via the [MASTER EQ EDIT] 
button are performance parameters (page 30).
■Using the Pitch Bend and 
Modulation Wheels
You can apply real-time vibrato or a pitch bend 
effect to a sound by using the pitch bend and 
modulation wheels. Using these wheels will 
increase the expressiveness of the sound, partic-
ularly in solo phrases.
Pitch bend wheel
Use the pitch bend wheel to bend notes up or 
down while playing the keyboard to add a pitch 
bend effect.
 “PitchBendRange” is a performance parameter 
(page 30).
Modulation wheel
You can apply vibrato effects to the sound, or change 
the amount of reverb or modulation effects, by mov-
ing the modulation wheel up and down.
TIP
To set the master equalizer frequency and Q, use the 
[MASTER EQ EDIT] button (page 71), which also enables 
you to set the gain. However, the latest gain setting by the 
sliders or [MASTER  EQ EDIT] button will remain in effect.
TIP
The master equalizer is globally applied to the P-250 the 
sound currently being played.
TIP
You can also access the channel equalizer via the [VOICE 
EDIT] button. This equalizer enables you to adjust the 
sound of each voice independently. (page 68)
TIP
When you set the “EqualizerLock” parameter (page 79), 
which is accessed via the [OTHER SETTING] button, to 
ON, the master equalizer settings will not be affected by 
performance recall or MIDI song playback.
HIGH HI-MID
MASTER EQUALIZER
LOWLO-MIDMID
When the corresponding slider is set to center, the equal-
izer level is set to normal.TIP
The pitch bend effect is applied only to the sound you are 
playing on the keyboard.
TIP
To set the bend range, use the “PitchBendRange” parameter, 
which is accessed by the [OTHER SETTING] button (page 79). 
TIP
If you set the “PitchBendRange” parameter too high, high 
notes may sound out of tune.
TIP
You can specify in Edit mode the effect you wish to control 
with the modulation wheel (see page 69). 
TIP
If you do not need to use the modulation wheel, you can 
turn it off so that you will not activate it accidentally during 
performance, or to avoid unnecessary transmission of MIDI 
messages (see page 69). 
TIP
The modulation wheel for some voices is disabled by 
default. In that case, operating the wheel will have no effect, 
unless you turn the wheel on.

■Using Pedals
The P-250 features four pedal jacks. Differ-
ent pedals can be used for various pur-
poses, as described below.
See page  23 for information on connecting 
the pedals.
Applying the sustain effect
Connect the included foot pedal FC3 to the PEDAL [1 
(SUSTAIN)] jack to sustain the current sound.
When you press and hold down the pedal, the effect 
is applied and all notes being played will sustain, 
even after you release the keys.
If you press the pedal while you are playing the 
“GrandPiano 1” voice, the soundboard and string res-
onance effects (sustain sampling) are applied.
Applying the sostenuto effect
Connect the included foot pedal FC3 to the PEDAL 
[2(SOSTENUTO)] jack to add a sostenuto effect to the 
current sound.
When you press the pedal, the effect will be applied 
to only the notes you are playing at that time, and the 
effect can remain longer even after you release the 
keys. The effect will not be applied to notes you play 
after you press the pedal.
Applying the soft effect
Connect the included foot pedal FC3 to the PEDAL [3 
(SOFT)] jack to add a soft effect to the current sound.
When you press and hold down the pedal, all the 
notes you play after you press the pedal will sound 
softer. (Note that the effect is not applied to the notes 
you were playing when the pedal was pressed. Press 
the pedal just before you start playing the notes to 
which you wish to apply the effect.)
Applying the expression effect
Connect an optional FC7 foot controller to the PEDAL 
[4(AUX)] jack to add an expression effect to the cur-
rent sound.
The faster you press the foot controller, the greater the 
effect applied.
■Using Panel Lock
The Panel Lock function temporarily disables 
the operation of the P-250 panel (locks the 
panel controls) so that you will not inadvert-
ently change the voice or mode during perfor-
mance.
Press the [PANEL LOCK] button twice quickly to 
turn the panel lock on or off.
When the panel is locked, [PANEL LOCK] 
appears on the display.
NOTE
This section explains how to use the pedals based on the 
default settings after the power is turned on. Since you can 
assign various functions to the pedal jacks, the resultant 
effect may differ, depending on the default settings. For 
more information, refer to [Pedal 1]/[Pedal 2]/[Pedal 3]/
[Pedal 4] (page 69) in the Voice Edit section.
TIP
Use the “SustainSamplingDepth” parameter in the “OTHER 
SETTING” menu to adjust the depth of the resonance effect 
for the damper pedal (page 78).
When you press the pedal here, 
the sound of notes you are 
playing, as well as subsequent 
notes will sustain.
When you press the pedal here, 
the sound of notes you are 
playing at the moment will 
sustain.
TIP
Use the “PedalStart/Stop” parameter in the “OTHER SET-
TING” menu to assign the Start/Stop function (same as the 
[START/STOP] button on the panel) to the pedal connected 
to the PEDAL [2 (SOSTENUTO)], [3 (SOFT)], or [4 (AUX)] 
jack (page 78).
TIP
You can reverse the effects of the pedals (such as on/off 
status and intensity) using the “PedalType” parameter 
(page 78) in the “OTHER SETTING” menu.
