Troubleshooting
Can I record an audio source such as guitar or vocals at the
same time that I record a MIDI performance from the JUNO-G’s
keyboard?
It’s not possible to record on an audio track at the same time
that you record MIDI from the JUNO-G’s keyboard. Record
your performance on the JUNO-G’s keyboard as MIDI, and
then overdub your audio performance on an audio track.
Sound Device Tones Are Switched Arbitrarily
Use the Microscope (p. 99) to check the following points.
• Has an unneeded program change been input? Or are there
duplicate program changes?
• Were any mistakes made in setting the data MIDI channels
when Program Change messages were input?
Data supposed to be present does not appear in microscope.
Check the following points.
• Are the wrong tracks selected?
• In View Select (p. 101), is any data set not to be displayed?
When I play back song data, I hear the sounds of the GM sound
generator.
If the song data contains GM System On, GM2 System On, or
GS Reset MIDI messages, the sound generator will switch to
GM mode. To prevent this, turn the following reception settings
“OFF” (p. 161).
[SYSTEM SETUP] MIDI Receive: Receive GM System On,
Receive GM2 System On, and Receive GS Reset On
Music data (GM scores) does not play back correctly
Check the following points.
• Has the Receive General MIDI/General MIDI 2 System On
Switch been turned ON?
Set the Receive GM System ON/Receive GM2 System ON
parameter (SYSTEM/MIDI/RX) to “ON” (p. 161).
• Are you trying to start playback from midway through the
song?
The beginning of a GM score song contains a General MIDI/
General MIDI 2 System On message. In some cases, a GM score
cannot be played back correctly unless this message is received.
• Are you trying to play song data designed for the GS Format?
When the JUNO-G receives a GS Reset message, the JUNO-G is
enabled for the GS format. This permits playback of music data
bearing the GS logo (GS music data). However, data created
exclusively for the Sound Canvas Series may not play back
properly on the JUNO-G.
After using a song recorder to play a song, sounds stopped
playing, and no sound is played even when Program Changes
are sent.
It could be that a Bank Select in the song data that is not
specified by the JUNO-G was encountered in the song. No
sound is played if the tone group is not one designated by the
JUNO-G with Bank Select MSB/LSB. Note that if you omit the
Bank Select, and send only the Program Change, the tone in the
currently selected group that has the specified Program Change
number will play. Try reselecting the tone using the panel
controls. Furthermore, when selecting tones from an external
MIDI device, be sure to send the Bank Select MSB/LSB and the
Program Change as a single set for reliable reproduction. First
sending the MSB and LSB (the order in which these are sent
does not matter), followed by the Program Change.
In some cases, you may be unable to hear any sound after
playing the last song that was faded-out. This may be because
the volume has been lowered by volume messages or
expression messages. Check the value of these messages, and
set them to appropriate values.
Performances are sluggish, or have interruptions.
Problems of sluggish and interrupted performances can crop up
very easily when the song recorder or sound generator used for
the performance has to handle heavy data loads.
Main causes and possible corrective measures are considered
below.
• Are more than 128 voices playing simultaneously?
Reduce the number of voices. The composition of JUNO-G
Patches is such that up to eight Waves may be used for one
Patch. When using such Patches, even though only one sound
may be heard, it is actually eight sounds that are being played
simultaneously. In addition, with certain sounds like
continuous sounds with long releases, even though the actual
sound may not be audible to you, processing for playing the
sound is still underway, so in these cases as well, the
performance data can differ from the actual number of voices
being played.
• Are you using a Patch that uses a lot of LFO?
Try changing to a different Patch. LFO processing invariably
places a big load on the machine, so heavy use of the LFO slows
down processing for the JUNO-G overall, which can end up
having affecting the expression of sounds themselves.
• Is the data concentrated at the beginning of the beats in the
sequence data?
Avoid overlapping data with the same timing by setting an
offset of 1–2 clocks instead. Data may easily become
concentrated at the beginning of the beats in the song data
when, for example, the song data is input using Step Recording,
or if the data is quantized after being input with a keyboard in
real time. Because of this, large amounts of data are sent to the
JUNO-G, and the processing for expressing sounds becomes
bogged down.
• Is there a Program Change at the point where the song
performance is sluggish?
Change the position of the Program Change. When Program
Changes are inserted in songs, processing time for switching
patches increases, which may then cause the performance to
become sluggish.
• Is there a System Exclusive message at the point where the song
performance is sluggish?
Move the location of the data. System Exclusive messages
