Safety and warning instructions 

IMPORTANT! Please read these instructions first! 

IMPORTANT INFORMATION: Complete safety when using the system is only guaranteed by PianoDisc if it has been installed correctly and is used correctly. Do not make any modifications of your own or encourage others to modify any part of the QuietTime systems, if PianoDisc has not specifically approved the modification. 

Read these instructions before operating the system! 

Interference from other devices on the same circuit may cause an unpleasant pop when the devices are switched on or off. Whenever possible, connect the QuietTime system to a dedicated outlet. The PianoDisc warranty does not cover interference caused by other devices, which typically have inadequate filtering circuits. To avoid unwanted popping noises, avoid switching other devices on or off while the QuietTime system is powered. 

Other safety and installation instructions 

You will find information in this list that covers possible personal injuries, electrical shock and causes of fire. WARNING! You must always abide by the basic precautions, including the following instructions, when using electrical equipment: 

1. Read all of the instructions before using the product for the first time. 

2. The product must be connected to the type of power supply stipulated in this user guide or on the product itself. 

3. Never open the QuietTime System case under any circumstances. 

4. Power is supplied through the plug. The system should only be connected to an electrical socket that is suitable for use with the attached plug. 

5. You should always try to keep the power cable a safe distance away from other objects. Make sure the cable is not: 

  • Tangled 

  • Placed in a frequently used area 

  • Trapped beneath the piano 

6. Do not position your piano and the QuietTime System in a location that is in direct sunlight or where they are subjected to water, humidity or hot and cold airflows. 

7. Your QuietTime System should be disconnected from the electrical outlet if it is not used for a long period of time. 

8. Only an authorized service agent should be contacted if your system needs repairing. 9. This product can generate volume levels that cause permanent loss of hearing when used alone or in conjunction with an amplifier, headphones or loudspeakers. Consequently, never run the QuietTime System for too long at a loud volume or even at a volume that is painful on the ears. Please visit an ear specialist before using your QuietTime System again if you experience a loss of hearing or if you experience ringing in your ears. 

10. The product must be installed so that there is adequate ventilation. 

11. Make sure no objects or liquids are able to leak into the system through the openings in the top of the equipment.

d) The system does not appear to work normally or it shows clear signs of working differently; or e) The system has been dropped or severely jolted, or the top of the equipment has been damaged.

General user information 

• Leaving the QuietTime System’s plug perpetually plugged into an electrical outlet causes it to continually draw power (approx. 0.1 Watt) and generate a small amount of heat. Disconnecting the piano’s plug from the electrical supply will completely isolate the unit unless the tone generator also has its own power supply. 

• Ensure the tone generator is always adequately ventilated from above, below and the rear. The QuietTime System’s tone generator must never be placed on a soft surface, such as a cushion or a towel. Never put any objects or containers on top of the tone generator. 

• If the QuietTime System does not respond in any way to your controls, as described in this manual, disconnect the unit from the power supply and contact your piano dealer or PianoDisc.

Calibrating Basic keyboard calibration 

INFO: The piano has to be calibrated after the QuietTime Magic 

Star System has been installed in your piano. The reason for 

this is that the Magic Star tone generator requires 

information about each key’s movement path. 

ATTENTION! Only a few or even none of the keys will function correctly if 

you do not run a calibration. It might also be necessary to 

run a new calibration if the location or the form of keys has 

changed over time, e.g. after the piano has been delivered 

to your house. 

How to perform a calibration: 

Conditions: 

a. Connect the keyboard sensors cable and the power supply to the 

QuietTime tone generator. Turn off the tone generator. 

b. Move the stop rail lever to the “Mute” position (piano switched to 

mute). 

c. Make sure there is nothing on the piano that can press down a key. 

Press and hold the Metr-button and then switch on the Magic Star System. 

Release the Metr-button after 3 seconds. 

The following is displayed after another five seconds: 

KEY SETUP 

Press every key and press [Metr.] when done.

Press each of the 88 keys fully down, one after the other, using your normal force and speed. After you have pressed all the keys, terminate the calibration process by pressing the Metr-button once. 

INFO: It will take a few seconds to save the data. After the data is saved, 

the system automatically returns to the Sound menu. Your 

QuietTime System is now ready. 

Readjusting How to readjust single keys 

single keys 

INFO: Follow the calibration steps listed on the previous page to ensure all 

of the keys are set to the same sensitivity. However, if you believe 

some keys play too loudly or softly, use the following procedure to 

readjust the sensitivity of each of those keys. 

Make sure you switch-off QuietTime System. 

Press and hold down the Rec-button and then switch-on the QuietTime 

System

 

Release the Rec-button after 3 seconds.

Pedal information 

The QuietTime System supports two pedals: the left pedal (soft) and the right pedal (sustain). 

The left pedal (soft) attenuates the tone slightly. 

The right pedal (sustain) lets all of the keys that were played continue to sound until the pedal is released. 

23 

Connecting the Magic Star up to external audio equipment. 

Use an audio cable to connect the QuietTime audio LINE OUT to your stereo system’s input connections. The output signal is an unbalanced, line level signal. 

The following illustration shows you how to connect QuietTime and a professional audio system together: 

LINE OUT

You can also connect an external audio source, such as a CD player, to the QuietTime audio LINE IN port. Connect one end of an audio cable to your audio source’s AUX or Line OUT port, and the other end to QuietTime’s audio line IN port. 

The tone you hear in the headphones is a mixture of the system’s piano tones and the external audio source. 

Use the system’s level control or the external audio source’s volume control to adjust the tone volume. 

LINE IN 

Level control 

24 

Connecting the Magic Star to external MIDI equipment. 

IMPORTANT! Please select Tone 001 Piano2 from the GM sound library to use MIDI. All of the notes played on the piano are then transferred to 

MIDI channel 1, as MIDI data. 

To send MIDI data to a MIDI synthesizer or computer 

Connect QuietTime’s MIDI OUT port to your computer or synthesizer’s MIDI IN port. See the following illustration: 

Note: Many computers do not have an integrated MIDI interface. If you do not have a MIDI interface, you will need to purchase one before you can connect your 

computer to the QuietTime system. 

To receive MIDI data from the MIDI keyboard/synthesizer or computer 

Connect a MIDI cable to the MIDI interface’s MIDI OUT port, then connect the other end to QuietTime’s MIDI IN port. 

INFO: You can have MIDI IN and OUT cables connected at the same time. If you are using a computer, make sure the “Pass Through” is switched off in your software. 

This prevents double notes from being played or recorded.
