GETTING STARTED
POWER
After safely connecting the supplied power supply firstly to the piano and then the mains, turn on the piano by pressing the POWER switch. The display will light up.
AUTO POWER OFF
The unit will Auto Power Off after 30 minutes of no operation, except when playing demo songs.
SETTING THE VOLUME
It is advised to set the [MASTER VOLUME] to “MIN” when powering on the piano, and then adjust the volume to your desired level when playing.
CONNECTIONS
USING HEADPHONES
The SDP-3 has a 1/4” output jack (PHONES) for connecting standard stereo headphones. The output volume level is controlled using the main master volume wheel. The internal speaker system is automatically muted when a pair of headphones is plugged into the PHONES jack.
USING AN EXTERNAL SOUND SYSTEM
The LINE OUT (R) and (L)(MONO) phono sockets can be used to connect the piano to an external sound system, such as a keyboard amplifier, inter-face, or mixer. When using one cable (for mono output), insert your cable into the (L)(MONO) out-put. Connecting two cables sends separate left and right audio signals down each cable, giving you stereo output.
AUX INPUT
The Aux Input 3.5mm jack allows you to mix an external sound source (such as a smartphone or MP3 player) with the piano’s internal sounds, for playback through the piano’s in-built speakers or headphone output. The volume of the Aux Input is controlled by the external sound source.
MIDI OUTPUT
Use this output to transfer MIDI data, including note and touch velocity, via a 5-pin MIDI cable (not included).
USING USB MIDI
The SDP-3 allows the transfer of MIDI via USB from the piano to an audio interface or “host.” Use the audio interface to control the MIDI signal.
SUSTAIN PEDAL
The foot pedal included with your digital piano can be connected to the SUSTAIN input and, when held down, allows the sound of the notes played to decay slowly, or “sustain.” A piano-style foot pedal may also be used. The sustain input will auto-detect the polarity of the sustain pedal used. Ensure the piano is turned off before connecting the pedal, otherwise it may not be recognised by the piano correctly. To change the polarity of the pedal, hold the foot pedal down during power up.
USING DC POWER INPUT
The power input is used to connect the piano to mains power. Only use the included power supply unit (PSU).
USING BATTERY POWER
Ensure all batteries are inserted correctly, as indi-cated by the +/- polarity markings. Replace all the batteries at the same time. Do not combine old and new batteries and do not mix battery types, as this can cause overheating, fire, or battery fluid leakage. Remove the batteries from the instrument if it is not to be used for a long period of time.
DEMO SONGS
The SDP-3 features 16 demo songs, each demonstrating a different voice.To select a demo song, press the [METRONOME] and [TEMPO] buttons simultaneously. The first demo song will feature the Piano 1 voice. The metronome and tempo buttons will flash. During playback, another demo song may be chosen by pressing a different voice select button. Alternatively, use the data control wheel to select different demo songs.To stop the demo song. Press the [METRONOME] and [TEMPO] buttons together again. To replay the current song from the beginning, press the flashing voice select button.
SELECTING A VOICE
The piano has 16 different built-in voices. These digitally sampled musical instrument sounds may be selected one at a time or layered to produce two voices at once. To select a main voice, press the appropriate voice select button on the right side of the front panel. This will select the voice name above the button. Pressing the [BANK] button allows you to then select the second set of voice names below the voice buttons. The data control wheel can also be used to select the different voices
LAYER MODE
In layer mode, two voices may be played simultaneously, each at individually selected volumes. To add a second voice to the currently selected one, first press the [LAYER] button and then use the data control wheel to select the desired layer sound. Both the selected voice button lights will be on when the sounds are layered. Please refer to the Function Menu for how to adjust the volume, octave, and pan (how much sound source is sent to the left and right speakers) settings of both the main and layer voices.
To exit the layer mode, press the [LAYER] button again.
SPLIT MODE
The piano keys can be “split” into two sections, allowing different voices to be played in the left and right hands. To add a second voice on the left-hand section of the piano to the voice currently selected, press the [SPLIT] button and use the data control wheel to select the desired left-hand voice. The point at which the piano is split can also be adjusted by holding down the [SPLIT] button for 2 seconds and then playing the desired split point key. Please refer to the Function Menu for how to adjust the volume, octave, and pan settings of the split voices. To exit the split mode, press the [SPLIT] button again.
REVERB & CHORUS
The in-built reverb and chorus effects can be added to selected voices and help add expression to your playing. The settings will be retained even when the power is turned off/on.
REVERB

CHORUS

The time signature of the metronome can be set using the data control wheel. The selected time signature will be shown on the display. The options are as follows: 2/2, 1/4, 2/4, 3/4, 4/4, 5/4, 6/4, 3/8, 6/8, 7/8, 9/8, 12/8. Please refer to the Function Menu for how to adjust the volume of the metronome.\
TEMPO

The speed of the tempo will be shown on the display. To turn off the metronome, press the [METRONOME] button again.
TWIN MODE
The SDP-3 can be divided into two sections that both play the same notes, voice, octave, and volume. This provides an ideal teaching function, allowing two people to play the same notes simultaneously. When using this mode, keys A1 to C3 make up the left-hand section and keys C#3 to C7 make up the right-hand section. To enter/exit the twin mode, press the [LAYER] and [SPLIT] buttons together. Using the twin mode will automatically exit the layer and split modes.
EQ ADJUSTMENT

The metronome can be turned on by pressing the [METRONOME] button, if desired. The metronome sound acts as a guide and will not be recorded. Recording will begin as soon as you start to play. The selected track light will flash throughout. To stop recording, press the [TRACK] button. Recordings will be stored even when the piano is turned off/on.
PLAYBACK
To listen to your recorded tracks, press the [PLAY] button. If there is nothing recorded on the track, the display will show “None.” To stop playback, press the [PLAY] button again. Playback will also stop automatically at the end of the recording. The tempo of your recorded track can be changed by pressing the [TEMPO] button and using the data control wheel to set the new tempo.
CLEARING RECORDED TRACKS
To erase the recorded tracks, select the track you want to clear and then hold down the [TRACK] button for 3 seconds to delete the recording. When recording a new track, any previous recording on that track will automatically be deleted.
FACTORY RESET
