About DSP
DSP makes it possible to digitally produce complex acoustic effects. The DSP is assigned to each tone whenever you turn on Digital Piano power.
Using the Digital Piano’s Pedals
Your Digital Piano comes equipped with three pedals: damper, soft, and sostenuto Pedal Functions

  • Damper Pedal
    Pressing the damper pedal while playing will cause the notes you play to reverberate for a long time. Halfpedal operation (pressing the pedal part way) is also supported.
    • When one of the GRAND PIANO tones or the MODERN piano tone is selected, using the damper pedal adds damper resonance that is similar to that produced on an acoustic grand piano.

  • Sostenuto Pedal
    Only the notes of the keys that are depressed when this pedal is pressed are sustained until the pedal is released.

  • Soft Pedal
    Pressing this pedal while playing suppresses notes played on the keyboard after the pedal was pressed, and makes them sound softer.

• If pressing the pedal does not produce the desired effect, it could mean that the pedal cord is not connected properly. Refer to step 1 under “To connect the cable” (page EN-34).

Disabling Damper Noise Output
Damper noise is a slight metallic ringing sound that is generated as the damper of an acoustic piano separates from the wires pedal when the damper pedal is pressed. The damper resonance of your Digital Piano normally includes damper noise, but you can perform the procedure below to disable its output. Damper noise can be applied to the four piano tones (three GRAND PIANO tones and MODERN).

  1. While holding down the FUNCTION button, press the Damper Noise keyboard key.
    • For details about using the keyboard keys for settings, see “Keyboard Keys Used for Configuring Settings” (page EN-20).

    CASIO PX-765 Digital Piano - screws

  2. Attach side panels A and B to back board C. Secure side panels A and B to the back board C using the screws you removed in step 1.
    • Attach the side panels so the side of the back board C where the joint connectors are inserted is facing towards the back of the stand.
    • If you have trouble inserting a screw into a joint connector screw hole, use a screwdriver to adjust the joint connector by rotating it.
    IMPORTANT!
    Joint connectors
    • When inserting a screw into a joint connector, keep your finger on the joint connector hole on the back of back board C to make sure the joint connector does not come  out of the hole.

  3. 1. If you plan to locate the piano and stand where it is not against a wall, you need to extend the anti-tip brackets at the base of side panels A and B. Remove the two screws (one on the outside of each side panel) that hold the brackets, and then slide the brackets as shown in the illustration. After extending the anti-tip brackets, reinstall the screws that secure them in place, but do not tighten the screws fully at this time.
    3-2. If you plan to locate the piano and stand against a wall, loosen the two screws (one on the outside of each side panel) that secure the brackets. You do not need to remove the screws in this case.
    • In this case, you do not need to remove the screws. Just loosen them.

  4. Insert angle brackets G into the gap between the anti-tipping bracket and the side panel.

  5. From the outside of side panels A and B, temporarily tighten the screws you loosened in step 3, above.

  6. Place the two ends of the pedal unit D onto the G brackets and secure them with E screws. Finish with H screw caps.

  7. While pressing the pedal unit down towards the floor, securely tighten the screws you partially tightened in step 5.

  8. From the back of the assembled stand, slide the piano into the grooves of side panel A and side panel B.

  • If some keys seem to be raised up after you remove the tape, press down to return them to their normal positions.

Connecting Headphones
Front
Connect commercially available headphones to the PHONES/OUTPUT jacks. Connecting headphones to either of the PHONES/OUTPUT jack cuts off output to the speakers, which means you can practice even late at night without bothering others. To protect your hearing, make sure that you do not set the volume level too high when using headphones.

  • Be sure to push the headphones plug into the PHONES/OUTPUT jacks as far as it will go. If you don’t, you may hear sound from only one side of the headphones.
  • If the plug of the headphones you are using does not match the PHONES/OUTPUT jacks, use the applicable commercially available adaptor plug.
  • If you are using headphones that require an adaptor plug, make sure you do not leave the adaptor plugged in when you unplug the headphones. If you do, nothing will sound from the speakers when you play.

Connecting Audio Equipment or an Amplifier
You can connect audio equipment or a music amplifier to the Digital Piano and then play through external speakers for more powerful volume and better sound quality.
IMPORTANT!

  • Whenever connecting a device to the Digital Piano, first use the VOLUME controller to set the volume to a low level. After connecting, you can adjust the volume to the level you want.
  • Whenever you connect any device to the Digital Piano, be sure to read the user documentation that comes with the device.

Tones and/or effects sound strange. Turning power off and then back on again does not eliminate the problem.
Example: Note intensity does not change even though I alter key pressure.| Turn off Auto Resume, and then turn power off and then back on again.| EN-25
I cannot transfer data after connecting the Digital Piano to a computer.| 1. Check to make sure that the USB cable is connected to the Digital Piano and computer, and that the correct device is selected with your computer’s music software.
2. Turn off the Digital Piano and then exit the music software on your computer.
Next, turn the Digital Piano back on and then restart the music software on your computer.| EN-27
It takes a long time before I can use the Digital Piano after I turn it on.| It takes about 20 seconds after you turn on power to perform the memory format operation. Wait until the format operation is complete. Note that you should take care to avoid turning off the Digital Piano while a data transfer operation with a computer is in progress.| EN-28
A tone’s quality and volume sounds slightly different depending where it is played on the keyboard.| This is an unavoidable result of the digital sampling process,* and does not indicate malfunction.

  • Multiple digital samples are taken for the low range, middle range, and high range of the original musical instrument. Because of this, there may be very slight differences in tonal quality and volume between sample ranges.
    When I press a button, the note that is sounding cuts out momentarily or there is a slight change in how effects are applied.| This happens when the sounds of multiple parts are sounding at the same time while using layer, using the Duet Mode, playing back a built-in tune, recording, etc. Pressing a button when one of these conditions exists will cause the effect setting that is built into the tone to change automatically, which causes notes to cut out momentarily or causes a slight change in how effects are being applied.
    I need to reset all Digital Piano data and settings to their initial defaults.| Hold down the FUNCTION, MIDI REC and E.PIANO 1 buttons, and press the power button to turn on power.
    I need to reset a specific setting to its initial default.| Hold down the FUNCTION button and press the + and – keyboard keys of the setting at the same time.
