Overview of the Fantom-XR
LFO (Low Frequency Oscillator)
Use the LFO to create cyclic changes (modulation) in a sound. The
Fantom-XR has two LFOs. Either one or both can be applied to effect
the WG (pitch), TVF (filter) and/or TVA (volume). When an LFO is
applied to the WG pitch, a vibrato effect is produced. When an LFO is
applied to the TVF cutoff frequency, a wah effect is produced. When
an LFO is applied to the TVA volume, a tremolo effect is produced.
LFO is not included in the rhythm tones (percussion instrument sounds).
Patches
Patches are the basic sound configurations that you play during a
performance. Each patch can be configured by combining up to four
tones. How the four tones are combined is determined by the
Structure Type parameter (p. 51).

Rhythm Sets
Rhythm sets are groups of a number of different percussion
instrument sounds. Since percussion instruments generally do not
play melodies, there is no need for a percussion instrument sound to
be able to play a scale on the keyboard. It is, however, more
important that as many percussion instruments as possible be
available to you at the same time. Therefore, each key (note number)
of a rhythm set will produce a different percussion instrument.
fig.04-004.e
Each percussion instrument consists of the following four elements.
(For details, refer to the explanations for “Tones.”)
WG (Wave Generator)
TVF (Time Variant Filter)
TVA (Time Variant Amplifier)

Performances
A performance has a patch or rhythm set assigned to each of the 16
parts, and can simultaneously handle 16 sounds.
Because the Fantom sound generator can control multiple sounds
(instruments) it is called a Multi-timbral sound generator.

Part
On the Fantom-XR, a “part” is something to which you assign a
patch or rhythm set. In Performance mode, each performance has
sixteen parts, and you can assign a patch or rhythm set to each part.
Example 1:A Patch consisting of only one Tone
(Tones 2–4 are turned off).
Example 2: A Patch consisting of four Tones.
