Troubleshooting
ProblemPossible causesSolution
The P-250 does not turn on. The P-250 has not been plugged in prop-
erly.Securely insert the female plug into the socket on 
the P-250, and the male plug into a proper AC out-
let. (page 16)
A click or pop is heard when the 
power is turned on or off.Electrical current is being applied to the 
instrument.This is normal.
Noise is heard from the P-250 
speakers.A mobile phone is being used near the P-
250 (or the ring tone is sounding).Turn off the mobile phone, or use it further away 
from the P-250. Using a mobile phone in close 
proximity to the P-250 may produce interference.
The overall volume is too low, or 
there is no sound at all.The [MASTER VOLUME] is set too low 
(page 16).Raise the [MASTER VOLUME] level. 
Headphones are connected (applicable 
only if the Speaker setting is [Normal 
HeadphoneSW]). (page 79)Disconnect the headphone plug.
Speaker setting is off. Set “Speaker” to “Normal” or “ON”. (page 79)
The “Local Control” function is set to off. 
(page 74)Turn the “Local Control” function on.
The “InternalTG” is set to off (page 70). Set the “InternalTG” to on.
“Expression” is assigned to one of the 
connected pedals or the modulation 
wheel.Assign any function other than “Expression” to the 
pedal.
The Master EQ gain level is low 
(page 38).Raise the Master EQ gain level.
The Part EQ gain level is low (page 68). Raise the Part EQ gain level.
The keyboard volume is lower 
than the song playback volume.The volume level for the keyboard perfor-
mance is set too low.Move the [SONG BALANCE] slider toward “KEY-
BOARD” to increase the keyboard volume.
The speakers do not turn off 
when a pair of headphones is 
connected.The speaker setting is on. Set “Speaker” to “Normal”. (page 79)
The buttons do not respond. While you are using a function, some but-
tons not used for the function are dis-
abled.If a song is recording or playing, stop recording or 
playback. Otherwise, press the [EXIT] button to 
return to the main screen. Then, perform the 
desired operation.
The sound sustains and does 
not decay when I press the 
pedal to which [Sostenuto] is 
assigned.With the voices in the ORGAN1, 
ORGAN2, STRINGS, CHOIR, or 
SYNTH.PAD group, or part of the XG 
group, the sound continues sustaining 
while you hold down the sostenuto pedal.This is normal.
Higher or lower notes do not 
sound correctly when the trans-
pose or octave setting is made.The setting range for the transposition 
and octave setting is C-2 - G8. (With the 
normal setting, the unit’s 88 keys cover 
the range of A-1 - C7.) If the lowest key is 
set to a note lower than C-2, it will pro-
duce a sound one octave higher. If the 
highest key is set to a note higher than 
G8, it will produce a sound one octave 
lower.This is normal.
The tempo does not change 
even though I recorded with 
tempo changes.Depending on the timing of the tempo 
changes, the changed tempo may not be 
recorded. In this case, the recording will 
be played back at the original tempo.
Make tempo changes when the recording 
track is selected and the red track indica-
tor is flashing. The same trick applies to 
editing the tempo after recording.This is normal.
Check the location at which the tempo was 
changed.

Troubleshooting
Appendix
Performance in Dual or Split 
mode is not recorded.
Track data is lost unexpectedly.For Dual or Split mode recording, the 
recording track for the second voice or 
the voice for the left-hand part is automat-
ically assigned (page 50). Therefore, if 
the track already contains data, the data 
will be overwritten during recording. Also, 
switching to Dual mode or Split mode in 
the middle of a song is not recorded. 
Therefore, the notes you play with the 
second voice (or the notes lower than the 
Split point) will not be recorded.This is normal.
I cannot change the time signa-
ture in the song after recording.Due to limitations, the time signature of 
some recorded songs may not be 
changed after the recording is complete.Press the [TOP] button to locate the top of the 
song, use the B [–]/[+] buttons to locate the mea-
sure in which you wish to change the time signa-
ture, then change it.
The song title is not correct. The “CharacterCode” setting may be dif-
ferent than that used when you named 
the song. Also, if the song was recorded 
on another instrument, the title might be 
displayed incorrectly.Use the “CharacterCode” parameter (page 55) in 
the “SONG FILE” menu to change the setting. 
However, if the song was recorded on another 
instrument, changing the “CharacterCode” param-
eter setting may not resolve the problem.
When I turn on the power to the 
P-250 in the normal way (without 
trying to reset it to the default 
settings), the performance file 
(that was selected before shut-
down) is not loaded.The “CharacterCode” setting (page 53) 
has been changed since you named the 
performance file.Set the “CharacterCode” parameter to the previ-
ous setting you made when you named the perfor-
mance file.
Before shutdown, the performance file 
was erased.Save the desired performance file to memory and 
load it again.
Storage memory may be defective. If the symptom does not go away, back up the files 
in memory, then set the “FactorySet” parameter to 
“MemoryFileIncluded” and reset the unit to the 
default settings.

Midi Data Compatibility
This section covers basic information on data compatibility, including whether or not other MIDI devices can 
play back the data recorded by P-250, and whether or not the P-250 can play back commercially-available 
song data or song data created for other instruments or on a computer.
Depending on the MIDI device or data characteristics, you may be able to play back the data without any 
problem, or you may have to perform some special operations before the data can be played back. If you run 
into problems playing back data, please refer to the information below.
Basic Check Points
The data and the MIDI device must match in 
regards to the items below.
•Sequence format
•Voice allocation format
Sequence Format
A system that records song data generally utilizes a 
specific “sequence format.”
•Playback is possible only when the sequence for-
mat of the disk matches that of the MIDI device.
[Common Sequence Formats]
■SMF (Standard MIDI File)
This is the most common sequence format.
•Standard MIDI Files are generally available as 
one of two types: Format 0 or Format 1.
•Many MIDI devices are compatible with For-
mat 0, and most commercially available soft-
ware is recorded as Format 0.
•The P-250 is compatible with both Format 0 
and Format 1.
•Performance data recorded on the P-250 is 
saved in SMF Format 0 in memory.
■ESEQ
This sequence format is compatible with many 
of Yamaha’s MIDI devices, including P-250 
series instruments.
•The P-250 is compatible with ESEQ. 
						

							P-25089
Midi Data Compatibility
Appendix
With MIDI, voices are assigned to specific num-
bers, called “program numbers.” The numbering 
standard (order of voice allocation) is referred to as 
the “voice allocation format.”
•Voices may not play back as expected unless the 
voice allocation format of the song data matches 
that of the compatible MIDI device used for 
playback.
[Main Voice  Allocation  Formats]
■GM System Level 1 (logo)
This logo (GM logo) is affixed to tone generators 
and music data that supports “GM system level 
1.”
“GM system level 1” is a standard specification 
for the sound map and MIDI functionality of a 
tone generator, and is designed to ensure that 
music data will produce essentially identical 
playback on tone generators from different man-
ufacturers or models.
•Many MIDI devices are compatible with GM 
System Level 1, as is most commercially avail-
able software.
•The P-250 is compatible with GM System 
Level 1.
■XG (logo)
This logo (XG logo) appears on tone generators 
and music data that supports “XG.”
XG is Yamaha’s tone generator format that 
extends “GM system level 1” to allow richer 
expressive power and future data compatibility.
•The P-250 is compatible with XG.
•Performance data recorded with preset voices 
on the P-250 can be played on other XG-com-
patible instruments.

GRANDPIANO1
(G.PIANO1)
GrandPiano1
This sound was sampled from a full concer t grand 
piano. Three stages of dynamics were sampled, and no 
effort has been spared in making the sound vir tually 
identical to that of an acoustic piano. Even the tonal 
changes produced by the damper pedal and the subtle 
sounds of releasing a key are reproduced. The sympa-
thetic vibration (string resonance) that occurs between 
the strings of an acoustic piano has also been simu-
lated. This sound is suitable for any style of music.
MellowPiano1A warm and mellow piano sound. Ideal for accompani-
ment of ballads or other songs.
RockPianoA bright-sounding piano. Ideal for rock styles.
HonkyTonk
Piano×A honky-tonk style piano. Enjoy a tonal character that is 
quite different than a grand piano.
