Roland Service Station.

Check the following points.
• Make sure that the JUNO-Di’s AC adaptor is correctly connected to
an AC outlet and to the rear panel power connector, and that the
adaptor itself and AC power cord are connected correctly (p. 17).
• If you’re using batteries, disconnect the AC adaptor from the JUNO-
Di. If batteries are installed, connecting or disconnecting the power
cord from the outlet or connecting or disconnecting the DC plug of
the AC adaptor while the JUNO-Di is turned on will cause the power
to turn off.

Check the level setting.
• The Part level settings may be too low.

Check the Effect settings ON or OFF (p. 61).
Also use the included “JUNO-Di Editor” to check the effect level and
other settings.

operations of the D Beam controller, or by MIDI messages (volume
or expression messages) received from an external MIDI device?

• Has the volume level of the part been lowered?
Check the level of each part (p. 60).

Check the system setting “SOUND” (p. 75).
