Troubleshooting
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.
You can use the Track Edit operation Data Thin (p. 143) to thin
out unwanted messages.
No Sound from connected MIDI device.
Check the following points.
Is the instrument set to transmit MIDI messages?
In Patch Mode
Kbd Patch Rx/Tx Channel parameter (Keyboard part) (p. 197)
Pad Patch Rx/Tx Channel (Pad part) (p. 197)
In Performance Mode
KBD switch (p. 68).
Exclusive messages are not received.
Check the following points.
Is the instrument set to receive Exclusive messages?
Set the Receive Exclusive parameter to “ON” (p. 198).
Does the Device ID number of the transmitting device match
the Device ID number of the Fantom-Xa?
Check the Device ID parameter (p. 197).
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-Xa 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-Xa’s MIDI Receive
channel are matched. The MIDI Receive channel used by the
Fantom-Xa 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
Mode (p. 194) is set to MIDI. Set the USB mode to Storage.
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
Local Switch parameter (p. 197).
In Performance Mode
KBD switch (p. 68).
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.
