Roland HP507 User Manual

HP507 uses a hammer action keyboard in order to simulate an acoustic piano’s playing touch as realistically as possible. For 

this reason, you’ll hear the hammers thump when you play the keyboard, just as you would when playing an acoustic piano. 

Since this unit allows you to adjust its volume, you might notice the sound of the hammers in certain situations, but this does 

not indicate a malfunction. If vibration transmitted to the floor or walls is a concern, you may be able to minimize the vibration 

by moving the piano away from the wall, or by laying down a commercially available anti-vibration mat designed for use with 

pianos.

–

When 30 minutes have elapsed since you last played or operated this unit, the power will turn off automatically. (This is the 

factory setting). 
If you don’t need the power to turn off automatically, turn the “Auto Off” setting “Off.”

Is the power cord connected correctly?

Could you have turned the power on again immediately after turning the power off?
Allow an interval of at least five seconds before turning the power on again.

Since the HP507 uses a liquid-crystal display, you may find that it is unable to display letters or other things in environments 

where temperatures go below 0 degrees Celsius (32 degrees Fahrenheit).

Is the pedal connected correctly?
Plug the cable firmly into the pedal connector.

If you disconnect the pedal cord from the HP507 while the power is on, the pedal effect may remain “stuck” in the  On condition.
You must power-off the HP507 before connecting or disconnecting the pedal cord.

Could you have changed how the pedal effect is applied?
If the damper pedal part is set to “Right,” the pedal will apply only to the right tone; if it is set to “Left,” the pedal will apply only to 

the left tone.

Could Twin Piano be turned on?
If Twin Piano is on, the right pedal will affect only the right-hand keyboard zone and the left pedal will affect only the left-hand 

keyboard zone.

Could you have changed the function of the pedal?
If you’ve reassigned the function of the center pedal, this pedal will not operate as the sostenuto pedal.

Are you using (optional) Roland USB flash drive?
Reliable performance cannot be guaranteed if you use non-Roland USB flash drive products.

If you are unable to read or write USB flash drive successfully, change the USB memory mode.

Are the external devices connected to more than one AC power outlet?
If you connect external devices, be sure to connect them to the same AC outlet.

If turn off the HP507, or the power is disrupted due to a power failure while you’re connected to a MIDI device, the settings of 

that MIDI device may be altered. If this occurs, power-off the HP507 and your MIDI device. Then power-on the HP507 first, and 

next power-on your MIDI device..

Is the speaker cable connected correctly?

Could the HP507’s volume or the volume of the connected equipment be turned down?

Could there be a plug inserted in a headphone jack?
The speakers will not produce sound if headphones or plug are connected to the headphone jacks.

Has Local Control been set to “Off”?

Could Twin Piano mode be set to “Individual”?
If headphones are connected when Twin Piano is On and the mode is set to “Individual,” notes played in the left-hand keyboard 

zone will not be heard from the headphones connected to the right Phones jack. Similarly, notes played in the right-hand 

keyboard zone will not be heard from the headphones connected to the left Phones jack.

Has Local Control been set to “Off”?
When Local Control is set to “Off,” no sound is produced by playing the song. Set Local Control to “On.”

Could the Song Balance be set to “0”?

Could the Visual Control mode be set to “MVC” or “V-LINK”?
If the Visual Control mode is set to “MVC” or “V-LINK,” the lowest 12 keys of the keyboard (A0–G#1) are used to control images; 

they will not produce sound.

Is the Master Tune setting appropriate?

Is the setting for the Temperament correct?

Is the settings for the Stretch Tuning correct?

The maximum simultaneous polyphony is 128 voices. If you are playing along with a song and making heavy use of the damper 

pedal, the number of notes the HP507 is attempting to produce may exceed the maximum polyphony, meaning that some of 

the notes will drop out.
