• Are the VL7 outputs properly connected to the amplifier/mixer
inputs?
• Are the connection cables shorted, open, or otherwise faulty?
• Is the VL7 connected to a high-sensitivity microphone or instru-
ment input on your amplifier or mixer? Try turning the VL7
DOWN controls down to avoid overloading the amplifier/mixer
inputs.
• Check the level and pan controls on the sound system/mixing
console being used with the VL7.

those of the external MIDI device used (page 153)?
