Troubleshooting
Problem
Power will not turn on
No sound
Sound Does Not Stop
No sound from Human
Voice/Vocal Designer/
Vocoder
The volume level of the
926b
instrument connected to
LINE INPUT is too low
Pitch is wrong
Something is wrong with
the sound when you play in
a high register
What to check
Is the AC adaptor connected correctly?
Are your amp, speakers, or headphones connected correctly?
Is the VP-7's volume at a high enough level?
Could Bypass be on?
If the input from the microphone is at too high a level, acoustic feedback could be produced, or
the sound might continue sounding endlessly. Adjust the level of the microphone's input.
If a keyboard is connected and you've selected a Vocoder sound, vocalizing into the microphone
will not produce sound unless you are also playing the keyboard.
If a keyboard is connected, there will be no sound unless the MIDI channels of the keyboard and
the VP-7 match.
Check the VP-7's MIDI receive mode and your keyboard's MIDI transmit channel.
Could Bypass be on?
Is the microphone switched on?
Is the microphone connected correctly?
Is the microphone input level raised?
Is the volume balance (Harmony) set appropriately?
When set to LR Output Mode, only the direct sound from the microphone will be output from OUT-
PUT (R). The sound from Human Voice/Vocal Designer/Vocoder will be output from OUTPUT (L).
To revert to the normal stereo output, you'll need to switch the unit off, then back on again.
Could you be using a connection cable that contains a resistor?
Use a connection cable that does not contain a resistor.
Is the tuning set correctly?
When playing high notes on the VP-7, you might notice that the sound stops or the pitch fails to
rise, or you might hear noise that changes depending on the keys you play (warbling, chirping,
rustling, beeping, buzzing, etc.). This occurs mainly when you exceed the upper limit of pitches
that the VP-7 is able to produce, and will be heard for notes that you will normally not use; it does
not indicate a malfunction.
