Cause/Action
Page
Power does not turn on
Is the AC adaptor connected correctly?
Nothing appears in the
screen
Since the VIMA uses a liquid crystal screen, it may happen that no text or graphics
appear in the screen if the temperature is below zero degrees Celsius (32 degrees
Fahrenheit).
–
The screen shows vertical
lines / Color is washed-out
at the edge of the screen
These are due to the nature of a liquid crystal screen, and are not malfunctions.
You can adjust the screen brightness to minimize these artifacts.
Pedal does not work, or is
“stuck”
Is the pedal connected correctly?
Plug the cable firmly into the pedal connector.
Device connected to the input
jacks has insufficient volume
Could you be using a connection cable that contains a resistor?
Use a connection cable that does not contain a resistor.

No sound
No sound
Could the VIMA’s volume or the volume of the connected equipment be turned
down?
Could headphones be connected?
Could there be a plug inserted in a headphone jack?
The speakers will not produce sound if headphones (or anything else) are
connected to the headphone jack.
Could the [BALANCE] knob be set all the way toward “KEYBOARD” or “SONG”?
No sound (when a MIDI de-
vice is connected)
Are all devices powered on?
Are the MIDI cables connected correctly?
Do the MIDI channels of the VIMA and the connected device match?
Not all the notes you play
are sounded
The maximum simultaneous polyphony is 64 notes. If you are playing along with
a song and making heavy use of the damper pedal, the number of notes the VIMA
is attempting to produce may exceed the maximum polyphony, meaning that
some of the notes will drop out.
