What's MIDI?

MIDI (short for Musical Instrument Digital Interface) allows a wide variety of electronic musical instruments, computers and
other related devices to connect and communicate with one another. MIDI carries event messages that specify notation, pitch
and velocity, controls signals for parameters such as volume, vibrato, audio panning, and programs change information to
change the voice selections.
The instrument can output real-time playback information via MIDI messages and control external MIDI devices. The instru-
ment can also accept incoming MIDI messages and generate sound accordingly.

Troubleshooting

Possible Cause and Solution
This is normal and is no cause for alarm.
1. Check if the master volume is set too low.
2. Check if headphones are plugged into the PHONES jack.
3. Check if the R1/R2/L1 voice volume is set too low (in the Mixer).
Using a mobile phone in close proximity to the instrument may
produce interference. To prevent this, turn off the mobile phone or
keep it away from the instrument when in use.
You may be playing keys in the right hand range of the keyboard. To
start the accompaniment with Sync Start, make sure to play keys in
the left-hand range.
Make sure that the tune value is set to 0. Hold down the [+/YES] and
[-/NO] buttons and turn on the power to restore factory settings.
Check if the USB cable is firmly connected. Try connecting another
USB port on the computer. This instrument is plug and play and
should work without installing a driver.
Check if the pedal cable is firmly connected.
Make sure your USB flash drive is in FAT32 format and not multi-parti-
tioned.
The auto power off function will turn off the instrument after a preset
period of time when the instrument is not in use. You can adjust the
auto-off function in the Function Menu.
