Standard MIDI files (SMF) a 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 Rx GM System ON/Rx GM2 System ON parameter
(SYSTEM/MIDI) to “ON” (p. 295).
• 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?
Data created exclusively for the Sound Canvas Series may not
play back properly on the Fantom-G.
After recording, the song does not sound when I play it back.
Have the tracks been muted?
Defeat muting (p. 134).
The tempo is different than the last time I played back the song.
If a song is played back after the tempo is changed, then the
new tempo is not saved unless the song is saved to the user
memory or USB memory. Conversely, the previous tempo will
be erased when you save the song. When saving songs,
carefully check the current tempo.
Sound Device Tones Are Switched Arbitrarily.
Use the Microscope (p. 250) to check the following points.
• Has an unneeded program change been input?
• 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.
• In View Select (p. 252), is any data set not to be displayed?
After using a MIDI sequencer 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 Fantom-G was encountered in the song. No
sound is played if the tone group is not one designated by the
Fantom-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 resettling 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 sequencer 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. 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.
In the Part Information window you can check the number of
notes for which sound is actually being processed (p. 132).
• 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 Fantom-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 tick 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 Fantom-G,
and the processing for expressing sounds becomes bogged
down.
