Troubleshooting
 
• 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 
Fantom-X, 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 
contain large amounts of data, thus placing a heavy burden on 
sequencers and sound modules. Try repositioning data and 
changing System Exclusive messages to Control Changes for 
any data for which Control Changes can be substituted.
• Is there an Aftertouch or other such large Control Change at the 
point where the song performance is sluggish?
Move the location of the data. If the data is no longer needed, 
delete the data. In some cases, when using a keyboard that 
features aftertouch to input data, you may end up inputting 
huge amounts of data before realizing this is happening. Such 
large amounts of data can place an excessive load on your 
sequencer and sound module.
 
No Sound from connected MIDI device.
Check the following points.
• Is the instrument set to transmit MIDI messages?
 
In Patch Mode
 
 
In Performance Mode

Exclusive messages are not received.
Check the following points.
• Is the instrument set to receive Exclusive messages?
• Does the Device ID number of the transmitting device match 
the Device ID number of the Fantom-X?
• Are you attempting to write to the User area? Data can be 
written to the User area only in Librarian mode.
I connected an external sequencer or MIDI keyboard to the 
MIDI IN connector, and attempted to play a Fantom-X rhythm 
set, but there was no sound. Why?
Check to make sure that the MIDI Transmit channel of the 
external MIDI device and the Fantom-X’s MIDI Receive channel 
are matched. The MIDI Receive channel used by the Fantom-X 
in Patch mode is set with the Kbd Patch RX/TX Channel 
parameter (keyboard part) and Pad Patch RX/TX Channel 
parameter (pad part). Rhythm Set performance data is generally 
received on MIDI Channel 10.
Messages from MIDI IN are not being received.
Additionally, the MIDI IN connector cannot be used if USB 
When using sequencing software, operating the knobs or other 
controls does not affect the sound.
For some sequencing programs, System Exclusive messages are 
not transmitted by the Thru function. If you are using such 
sequencer software and want to record system exclusive 
messages, turn on the following parameters.
 
In Patch Mode
 
 
In Performance Mode
 
When the Bend Range for a Patch is increased (48), the pitch 
does not rise sufficiently, even when a MIDI Pitch Bend 
message is received.
While Patch Bend Ranges can be set anywhere between 0 and 
48, when certain Waves in which the pitch is raised (in the + 
direction) are used, the pitch may stop rising at a fixed point, 
rather than continuing to go up. Although a value of 12 is 
ensured for the upper limit of raised pitches, use caution when 
setting the Bend Range above this figure.
