Issues Related to Sequencer
Song data 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. 193).
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 Fantom-S receives a GS Reset message, the Fantom-S 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 RD-700.
After recording, the song does not sound
when I play it back.
Have the tracks been muted?
Defeat muting (p. 85).
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 memory card. Conversely, the previous tempo will be
erased when you save the song. When saving songs, carefully check
the current tempo.
Locate Positions set in song have disappeared.
Check the following points.
Was the disk saved in a format other than MRC-Pro format (SMF
0 or 1)? Locate positions will be saved with the song data only
when saving in MRC-Pro format.
Are you using Quick Play? In order to use locate positions, the
song must be loaded into the Fantom-S.
Sound Device Tones Are Switched Arbitrarily
Use the Microscope (p. 162) 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. 164), 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-S was encountered in the song. No
sound is played if the tone group is not one designated by the
Fantom-S 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.
For more about the relationship between the Bank Select MSB/
LSB and corresponding tone groups, refer to
<Bank Select and
Program Change Correspondence Chart>
(Parameter List).
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 64 voices playing simultaneously?
Reduce the number of voices. The composition of Fantom-S
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.
In the Part Information window you can check the number of
notes for which sound is actually being processed (p. 43).
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-S overall, which can end up
having affecting the expression of sounds themselves.
Is the data concentrated at the beginning of the beats in the
