Troubleshooting
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 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 (Owners
Manual; p. 90, p. 111).
• 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 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 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, 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.
You can use the Track Edit operation Data Thin to thin out
unwanted messages. For details refer to Owners Manual (p. 151).
Issues Related to MIDI and External
Devices
No Sound from connected MIDI device.
Check the following points.
• Is the instrument set to transmit MIDI messages?
• In Patch Mode
Patch/Rhythm Tx Ch parameter (SYSTEM/MIDI)
• In Performance Mode
Ext Switch parameter (PERFORMANCE/Zone)
• Does the MIDI transmit channel for the Fantom's keyboard
controller section match the MIDI receive channel for the
connected MIDI device?
• In Patch Mode
Patch/Rhythm Tx Ch parameter (SYSTEM/MIDI)
• In Performance Mode
Transmit Channel parameter (PERFORMANCE/Zone)
Exclusive messages are not received.
Check the following points.
• Is the instrument set to receive Exclusive messages?
Set the Rx Exclusive parameter (SYSTEM/MIDI) to “ON”
(Owner’s Manual; p. 183).
• Does the Device ID number of the transmitting device match the
Device ID number of the Fantom?
Check the Device ID parameter (SYSTEM/MIDI) (Owner’s
Manual; p. 183).
* If you wish to rewrite the User memory settings by System Exclusive
messages, set the Exclusive Protect parameter to “OFF” (Owner’s
Manual; p. 183).
I connected an external sequencer or MIDI
keyboard to the MIDI IN connector, and
attempted to play a Fantom 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's MIDI Receive channel
are matched. The MIDI Receive channel used by the Fantom in Patch
or Rhythm Set mode is set with the Patch/Rhythm Rx Ch parameter
(SYSTEM/MIDI). Rhythm Set performance data is generally
received on MIDI Channel 10, but factory settings have the Patch/
Rhythm Rx Ch parameter value set to 1.
