Frequently Asked Questions - WK-300 NUX

How do I assemble the stand?

Follow the Quick Installation Guide in the manual. Attach side boards, back board, and headphone hook. Ensure the adjusting screw under the pedal is screwed close to the ground to prevent damage.

Can I connect headphones?

Yes, use a standard 6.35mm stereo headphone. Plugging it into the Headphone Jack on the back panel automatically mutes the built-in speakers.

How do I select different sounds?

Press the [DATA▼/▲] buttons to cycle through 128 tones (listed in the appendix). Press [VOICE] to return to the default grand piano tone.

What does the FUNCTION button do?

Pressing [FUNCTION] activates function selection. While its indicator is on, press a key within 5 seconds to assign a function (e.g., split, dual voice, reverb). It exits automatically after 5 seconds of inactivity.

How can I record my playing?

Press [RECORD] to enter standby (indicator lights). Play any key to start recording (max 48,000 notes). Press [RECORD] again to stop. Use [PLAY/STOP] to listen. Note: recordings are lost when power is off.

What are the dynamic curves and how do I change them?

There are four dynamic curves: Soft, Standard, Hard, and Dynamic On/Off. Press [FUNCTION] then press the corresponding key (as shown in the manual) to adjust touch sensitivity. Default is Standard.

How do I use the metronome?

Press [METRONOME] to start (default 120 BPM). Use [DATA▼/▲] to adjust tempo (20-280 BPM). Press [METRONOME] again to stop. Beat can be set via FUNCTION key to 1-6.

My piano produces no sound when keys are pressed. What should I do?

Check that Master Volume is turned up and no headphones are plugged in. If headphones are connected, speakers are muted. Also ensure power is on and the AC adapter is properly connected.

Can I connect the piano to a computer?

Yes, use a USB cable to connect the USB MIDI Jack on the back panel to your computer. This allows MIDI production and interaction with DAW software.

What should I do if the keys produce no sound or have inconsistent dynamics?

First, ensure Dual Keyboard or Transposition is not active. Reset them via FUNCTION. If dynamics feel different, check the current dynamic curve setting. Otherwise, reset the piano by turning it off and on.

Trouble Shooting

Trouble	Possible Reason/Solution
The digital piano will puff when it is switched on.	Don't worry. This is normal.
Pressing key makes no sound after the power is on.	Please confirm whether the master volume button is set properly or confirm whether the headphone jack is linked to other devices, which will automatically cut off the built-in speaker system.
Notes have different quality under the same sound.	This is normal because different sound sampling ranges make different sound quality.
In pedal sustain function, some sound sustains longer, others shorter.	This is normal. The tenuto of different sounds of this digital piano has been set to optimized length.
The sound is too small.	Please confirm whether the master volume button is set properly.
Some MIDI Data can not be transmitted correctly (Even the MIDI cable is linked correctly).	This is normal. It is related to the original setting.
The speaker will make noise when cell phone is nearby.	The cell phone will jam when it is nearby. The cell phone should be turned off or keep the cell phone away from the digital piano to avoid the jam.
The pitch doesn't match with key actual place while playing.	Maybe the double keyboard function or transposition function is turned on. Turn off double keyboard or reset transposition to zero can solve the problem.

Trouble	Possible Reason/Solution
The sound can not be changed while playing. The pitch doesn't match with key actual place.	Maybe the double keyboard function is turned on and the split point is set to the highest pitch. Turn off double keyboard function and set split point to original status can solve the problem.
The demo song distorts or interrupts.	Maybe it has been playing in maximum power for a long time so that the circuit board self-protection system is activated in case of overheat. Turn down the volume or turn off power for a while can solve the problem.
There are two sounds at the same time while playing.	Maybe you turn on dual voice function. Turn off dual voice function can solve the problem.
The tone's pitch is wrong.	Set scale and tones or set temperament parameter values to zero.
No automatic accompaniment chord.	Confirm whether accompaniment volume or chord function is turned on.
Dynamics is different from before.	This digital piano has four dynamics, light, standard, heavy, off. Maybe you have chosen different dynamics. You can choose the dynamics again according to your demand or reset it.
