Before You Play

Using the Pedals

The pedals perform the following operations. You’ll use them mainly when playing piano.

About the Adjuster

If you feel that the pedal is unstable (for example if you’ve moved the HP307 to a different location), you can adjust the adjuster located on the bottom of the pedals as follows.

Soft Pedal

Sostenuto Pedal

Damper Pedal

Damper Pedal (right pedal)

Use this pedal to sustain the sound.

While this pedal is held down, notes will be sustained for an extended time even if you release your fingers from the keyboard.

The length of sustain will change subtly depending on how deeply you press the pedal.

When you press the damper pedal of an acoustic piano, a slight noise is heard when the damper frees the strings, and a richly spacious resonance is added by the strings that vibrate in sympathy with the strings of the notes you actually play. The HP307 replicates the sound created when the damper releases the string (“damper noise”) and the sympathetic vibration (“damper resonance”).

You can modify the sound of the damper releasing the string and the sound of the sympathetic vibration (p. 35).

Sostenuto Pedal (center pedal)

The notes you are pressing when this pedal is depressed will be sustained.

Soft Pedal (left pedal)

This pedal is used to make the sound softer.

Playing with the soft pedal depressed produces a sound that is not as strong as when otherwise played with the equivalent strength. This is the same function as the left pedal of an acoustic piano.

The softness of the tone can be varied subtly by the depth to which you press the pedal.

You can switch the function of the sostenuto pedal and soft pedal (p. 58).

If you disconnect the pedal cord from the HP307 while the power is turned on, the pedal effect will remain applied. You must connect or disconnect the pedal cord while the HP307’s power is switched off.

Adjuster

Turn the adjuster to lower it until the adjuster is in firm contact with the floor. The pedal may be damaged if there is a gap between the adjuster and the floor. In particular, when you’ve placed the HP307 on carpet, you must turn the adjuster until it is pressing firmly against the floor.
