Overview of the Fantom-S
 
LFO (Low Frequency Oscillator)
 
Use the LFO to create cyclic changes (modulation) in a sound. The 
Fantom-S 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. 46).

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.

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. 
Use the Layer screen if you want to play two or more patches 
together (Layer) or play different patches in separate areas of the 
keyboard (Split).
Use the Mixer screen if you want to “mix” by individually adjusting 
the pan and level settings for each of the sixteen parts.
Because the Fantom sound generator can control multiple sounds 
(instruments) it is called a Multi-timbral sound generator.
