The front panel features a digital display, three control buttons (Volume, Program, Reverb), and a large rotary data knob. The display shows the current setting for the selected parameter.
Figure 2: Rear panel connections of the PianoBox Mini.
The rear panel includes a headphone output, MIDI IN port, USB Host port, DC5V Micro-USB charging port, and the power button.
4.2. Connecting a USB MIDI Keyboard
To use your USB MIDI keyboard without a computer, connect the USB cable from your keyboard directly to the USB HOST port on the PianoBox Mini. The PianoBox Mini can also provide power to your USB keyboard (up to 500 mA).
4.3. Connecting a Standard MIDI Device
For keyboards or other MIDI devices with a standard MIDI OUT port, use the included 3.5 mm TS to MIDI cable. Connect the 3.5 mm end to the MIDI IN port on the PianoBox Mini and the 5-pin DIN end to the MIDI OUT port of your external device.
4.4. Charging the Battery
Connect the included Micro-USB cable to the CHARGE port on the PianoBox Mini and the other end to a standard USB power adapter (not included) or a computer USB port. The low battery indicator will illuminate when charging is required. A full charge provides up to five hours of battery life.
5. Operation
5.1. Powering On/Off
Press and hold the Power Button on the rear panel to turn the unit on or off.
5.2. Adjusting Volume
Press the VOLUME button. The display will show the current volume level. Rotate the large DATA knob to increase or decrease the volume. The volume range is typically from 0 to 127.
5.3. Changing Programs (Sounds)
Figure 3: Display showing a program number.
Press the PROGRAM button. The display will show the current program number. Rotate the large DATA knob to cycle through the 128 available General MIDI sounds. Each number corresponds to a specific instrument sound.
5.4. Adjusting Reverb
Press the REVERB button. The display will show the current reverb level. Rotate the large DATA knob to adjust the amount of reverb applied to the sound.
5.5. Using with Computer Software (Latency Reduction)
When using music software (e.g., Sibelius, Finale, PrintMusic, MusicTime, Sonar, Pro Tools), the PianoBox Mini can help eliminate latency. Connect a USB MIDI interface (such as the MidiLink Mini, not included) from your computer to the PianoBox Mini. Configure your music software to use the PianoBox Mini for audio playback instead of your computer's internal soundcard. This setup bypasses potential delays between striking a key and hearing the sound.
6. Maintenance
6.1. Battery Care
To prolong battery life, avoid fully discharging the unit frequently. Recharge the battery when the low battery indicator appears. If storing the unit for an extended period, ensure it has a partial charge (around 50%) and recharge every few months.
6.2. Cleaning
Wipe the unit with a soft, dry cloth. Do not use liquid cleaners or abrasive materials, as they may damage the surface or internal components.
7. Troubleshooting
- No Sound: Ensure the unit is powered on, volume is up, and headphones/speakers are connected correctly. Check MIDI connections and ensure the correct program is selected.
- Unit Not Powering On: Ensure the battery is charged. Connect the Micro-USB cable to a power source and try again.
- USB Keyboard Not Working: Verify the USB cable connection. Ensure the USB keyboard is compatible and does not exceed the 500 mA power limit of the PianoBox Mini's USB Host port.
- Latency Issues with Software: Confirm your music software is configured to output MIDI to the PianoBox Mini via your MIDI interface, and that the PianoBox Mini is selected as the audio output device.
