There are three pedals: Damper, Soft, and Sostenuto. You can enjoy expressive performances that feel
closer to that of a grand piano using the pedals.
Damper Pedal
Pressing the damper pedal while playing will cause the notes you play to be sustained.
When a grand piano tone is selected, you can also create a resonance effect (Damper Resonance)
similar to when using a damper pedal on an acoustic grand piano. The pedal also supports half-pedal
operation, so pressing the pedal part way applies only a partial damper effect.
Soft pedal
Pressing this pedal while playing suppresses notes played on the keyboard after the pedal was
pressed, and makes them sound softer. The AP-300 supports half-pedal operation.
Sostenuto Pedal
Only the notes of the keys that are depressed when this pedal is pressed are sustained, even if the
keyboard keys are released, until the pedal is released.

Recording a Performance
EN-65
The Digital Piano has two recording functions: a MIDI Recorder and an Audio Recorder. Depending on
the type of data you want to record or play back, you will need to switch the [Recorder] setting between
<MIDI Recorder> and <Audio Recorder>.
MIDI Recorder
Performances are converted to MIDI data
*
and recorded to two tracks (data domain where
performances are recorded) in the internal memory.
• Keyboard performance information (keys touched and released, touch strength, etc.) is recorded as
MIDI data.
• MIDI data has the benefit of being extremely small in size compared to audio data, and it can be
edited at a later date, e.g., on a computer.
• One song can be recorded. When a new recording is made, the previous recording is erased.
• The maximum number of notes that can be recorded in one song is approximately 10,000 notes as a
total for both tracks.
* MIDI
MIDI is an abbreviation for Musical Instrument Digital Interface. It is a unified standard that allows
performance information (keys pressed and released, touch strength, etc.) to be exchanged between
electronic musical instruments or between electronic musical instruments and computer equipment,
regardless of manufacturer. The performance information exchanged is called MIDI data.

Audio Recorder
Convert your performance into audio data
*
and record it to a USB Flash Drive.
• The sound itself is recorded as audio data, similar to recording on a portable music player or tape
recorder.
• Audio data files are extremely large in size compared to MIDI data. However, they have the
advantage of being easy to listen to on a computer or portable music player.
• Up to 25 minutes and up to 99 files can be recorded on a USB flash drive.
* Audio Data
Audio data recorded with this Digital Piano is saved in WAV file format (linear PCM, 16 bit, 44.1 kHz,
stereo).
You can also:
Record a performance while playing back a song recorded using the MIDI Recorder
• For information about data file formats that are supported by this Digital Piano, see “Types of Data
that Can be Handled by this Digital Piano”.
• Data recorded on the Digital Piano can be saved to a USB flash drive. See “Saving MIDI Recorder
Songs to a USB Flash Drive”.

Troubleshooting
Cause: a. Gloved hands, fingernails, a stylus, etc. were used to touch the buttons.
b. The touch button sensitivity setting is not appropriate.
Solution: a. Firmly touch the touch buttons with bare fingers.
b. Change the touch button sensitivity setting. For more information, see “When Touch
Buttons Do Not Respond”.
Cause: a. The volume is turned down with the volume knob.
b. Headphones are connected. Or, the headphone conversion plug is left in the
PHONES/OUTPUT jacks.
c. The [Local Control] setting is turned <Off>.
d. The [Speaker Out] setting is set to <Off>.
Solution: a. Turn the volume knob.
b. Unplug the headphones or conversion plug from the PHONES/OUTPUT jacks.
c. Set the [Local Control] setting to <On>. For more information, see “Local Control”.
d. Set the [Speaker Out] setting to <Auto> or <On>. For more information, see “Speaker

Cause: a. The keyboard key tone (Transpose) has been changed from the default setting.
b. The fine tuning (Tuning) setting for sound pitch is set to a frequency other than
440.0 Hz.
c. Octave shift is set.
d. Scale Tuning is set to something other than the equal temperament.
Solution: a. Reset [Transpose] to the default setting. Or, turn the power off and then back on. For
details, see “Changing the Pitch in Semitone Steps (Transpose)”.
b. Set the [Tuning] setting to 440.0 Hz. Upper2 Detune: Lower Restore Detune to the
default setting. For details, see “Fine-tuning (A-tuning)” and “Fine-Tuning the Upper2
Part (Upper2 Detune)”, “Fine-Tuning the Lower Part (Lower Detune)” for more
information.
c. Set the Octave Shift setting to 0. For details, see “Shifting by Octaves (Octave Shift)”.
d. Set the Scale Tuning setting to equal Temperament.

Troubleshooting
EN-123
Sound does not become stronger or weaker when I change the way I play (touch).
The tone of the sound, effects, and so forth, do not change (i.e., the Digital Piano
does not return to its default settings), even after turning the power off and back on
again.
Cannot send or receive MIDI when connected to a computer.
Some tones have the same timbre but slightly different sound quality and volume
depending on keyboard position.
When pressing buttons, the sound that is being played is temporarily interrupted or
the sound quality sounds slightly different.
I don’t know how to delete a User Song.
I can’t play songs recorded directly to a USB Flash Drive.
Cause: [Touch Response] is set to <Off>.
Solution: Set [Touch Response] to a setting other than <Off>. For details, see “Changing the
Volume Made by the Strength of Pressure Placed on a Key (Touch Response)”.
Cause: [Auto Resume] is set to <Enable>.
Solution: Turn [Auto Resume] to <Disable> then turn the power off and back on again. For more
information, see “Saving the Digital Piano Settings (Auto Resume)”.
Solution: • Check that the Digital Piano is properly connected to the computer with a USB cable, or
that the correct is selected in the settings of the computer’s music software.
• Turn off the power to this Digital Piano and close the music software on your computer, then
turn on the power to this Digital Piano and restart the music software on your computer.
Cause: This is a boundary between sound ranges caused by electronic processing called digital
sampling
*
and is not a malfunction.
* This process records the original sound of the instrument in
multiple ranges, including
low,
mid, and high ranges, and creates a single tone in order to re
produce the sound
quality of each rang
e of the original instrument.
Cause: When using Layer, Duet, playing a Built-in Song, or using the recording function, multiple
parts sound simultaneously. If you press buttons in such a case, the tone-specific internal
effect settings will be automatically changed, and depending on the part, this
phenomenon may occur, but it is not a malfunction.
Solution: Deletion of User Songs can be executed from a smart device connected to the Digital
Piano. For details, see the instruction manual for the dedicated app.
https://web.casio.com/app/en/music_space/manual/
Solution: Try formatting the USB flash drive in exFAT format on your computer and then formatting
it on the instrument. For more information, see “Formatting a USB Flash Drive”.

– A roomy, well ventilated location.
Do not cover the AC adaptor with newspaper, table cloth, curtain, or any other type of fabric.
– Use a power outlet that is located near the Digital Piano.
This will let you immediately unplug from the power outlet should any problem occur.
• When using the AC adaptor, place it on the floor with its label surface downwards. The AC adaptor
becomes prone to emitting electromagnetic waves when the label surface is facing upwards.
