Performances are sluggish, 
or have interruptions
The sound will be interrupted if the maximum polyphony 
is exceeded.
Try reducing the number of notes that are played.
In some cases, sustained notes with a long release might cause 
processing to continue even though the notes are no longer actually 
audible. In such cases, the polyphony of the performance data differs 
from the number of notes that you hear.

Is there an Aftertouch or other such large Control Change 
at the point where the song performance is sluggish?
If the data is no longer needed, delete the data. p. 93
Is the data concentrated at the beginning of the beats in 
the sequence data?
Try spreading the data apart so that it does not occur at the same 
timing. It is easy for data to be concentrated at the first beat of the 
song if you use step recording to enter the song data, or if you apply 
quantization after realtime input from the keyboard. This causes a large 
amount of data to be sent to the FANTOM in a short time, possibly 
causing a delay in note processing.
p. 86
Problems with saving
A scene sounds different 
than when you saved it
Save the tones.
If you edit the tones used by scene, or if the temporary tones of the 
scene were rewritten from an external MIDI device, you’ll need to save 
those tones as well.
p. 48
Check the effect settings.
It might be that the master effect (system effect) settings have 
changed.
p. 55
Arpeggio and controller 
settings differ between 
studio sets
Check the arpeggio and controller settings.
Arpeggio and controller settings are independently saved for each 
scene.
p. 31
Problems with external MIDI devices
No sound from an external 
MIDI device
Does the MIDI transmit channel of the zone set to EXT 
match the MIDI receive channel of the connected device?
Match the zone’s transmit channel with the connected device’s receive 
channel.
For details, refer to “Parameter Guide” (PDF).
–
Is the zone that you want to output MIDI unlit, or set to 
EXT?
Unless the current zone is unlit, or unless one of the zones is set to EXT, 
playing the keyboard will not transmit MIDI messages.
p. 8
Is the zone set to EXT assigned to output MIDI?
Unless the zone set to EXT is the current zone, or unless the keyboard 
is connected via a layer that includes another current zone, MIDI 
messages are not transmitted.
p. 8
Exclusive messages are not 
received
Could Receive Exclusive be turned “OFF”? Turn Receive Exclusive “ON.” p. 115
Does the transmitting unit’s Device ID number match the 
FANTOM’s Device ID number?
Set the Device ID numbers. p. 115
When the tone’s bend range 
is large (48), the pitch does 
not rise to its full extent 
when a MIDI pitch bend 
message is received
Although a tone’s bend range can be set in a range of 
0–48, there are some waves for which the pitch cannot 
rise to the full extent of the pitch bend message, causing 
the pitch to stop rising at a certain point. We guarantee 
that the pitch will rise at least to a pitch bend range 
setting of 12, but please use caution if you specify a bend 
range that is greater than this.
