If you encounter one of the problems listed below, please check the possible causes and
solutions before you assume that your RY20 is faulty.
■ Troubleshooting
Problem Possible Causes and Solutions
No sound Make sure the VOLUME control is turned up to a reasonable level.
The VOLUME control affects the level of both the OUTPUT jacks
and the PHONES jack.
Check the levels set in the MIDI functions, Volume and Expression
(seepage 116).
The level of the drum pad is set to zero (see page 86).
The pattern or song that you selected is empty.
The tracks of the selected pattern or song have been muted (see
page 20).
If you are using an external sound system, check the connections
between the RY20 and the sound system. Look for possible
connection failures or shorts.
Make sure the volume control(s) on your external sound system is
turned up to a reasonable level.
Make certain that the RY20 is properly connected to the Yamaha
AC adaptor that is included and that the power is turned
ON.
Distorted sound Bad connections and faulty audio cables can cause distorted sound.
Make sure the cable plugs are clean and that all cable connections
are secure.
If your RY20 is connected to an external sound system, check that
the RY20 VOLUME control is not turned up too high, thereby
overloading the input to your sound system and causing distortion.
The pads produce sound, but the
songs or patterns will not play
This problem is most likely caused by an improper MIDI Sync
setting (see page 110). If you are not synchronizing the RY20 to an
external MIDI clock signal, make sure the MIDI Sync is set to
“INT” (internal clock).
If you are synchronizing the RY20 to an external MIDI device and
have set the MIDI Sync to “MIDI” (MIDI clock), make sure that the
MIDI OUT connector of the external MIDI device is properly
connected to the RY20 MIDI IN connector and that the external
device is transmitting an appropriate MIDI clock signal to the
RY20.
The RY20 does not respond to
MIDI control
Check that the RY20 MIDI channels are set to match the channels
of the controlling MIDI device. The RY20 has three MIDI channel
settings – drum channel (page 111), bass channel (page 112), and
program change channel (page 113). Make sure these parameters
are set properly for the type of MIDI control you are attempting.
Check your MIDI connections and cables carefully.
