Overview of the Fantom
About Simultaneous Polyphony
The Fantom can play a maximum of 64 sounds simultaneously. The 
following paragraphs discuss what this means, and what will 
happen when more than 64 simultaneous voices are requested from 
the Fantom.
Calculating the Number of Voices 
Being Used
The Fantom is able to play up to 64 notes simultaneously. The 
polyphony, or the number of voices (sounds) does not refer only to 
the number of sounds actually being played, but changes according 
to the number of tones used in the patches, and the number of 
Waves used in the tones. The following method is used to calculate 
the number of sounds used for one patch being played.
(Number of Sounds Being Played) x (Number of tones Used by 
Patches Being Played) x (Number of Waves Used in the tones)
For example, with a patch combining four tones, each of which uses 
two Waves, the actual number of sounds being played comes to 8. 
Also, when playing in Multitimbre mode or Performance mode, the 
number of sounds for each part is counted to obtain the total number 
of sounds for all parts.
How a Patch Sounds
When the Fantom is requested to play more than 64 voices 
simultaneously, currently sounding notes will be turned off to make 
room for newly requested notes. The note with the lowest priority 
will be turned off first. The order of priority is determined by the 
Voice Priority
Voice Priority can be set either to “LAST” or “LOUDEST.” When 
“LAST” is selected, a newly requested note that exceeds the 64 voice 
limit will cause the first-played of the currently sounding notes to be 
turned off. When “LOUDEST” is selected, the quietest of the 
currently sounding notes will be turned off. Usually, “LAST” is 
selected.
Note Priority in Multitimbre/
Performance Mode
Since Multitimbre/Performance mode is usually used to play an 
ensemble consisting of several patches, it is important to decide 
which parts take priority. Priority is specified by the 
Voice Reserve
 
Voice Priority
 setting of the patch 
will apply.
Voice Reserve
The Fantom has a 
Voice Reserve
 function that lets you reserve a 
minimum number of notes that will always be available for each 
part. For example if Voice Reserve is set to “10” for part 16, part 16 
will always have 10 notes of sound-producing capacity available to it 
even if a total of more than 64 notes (total for all parts) are being 
requested. When you make Voice Reserve settings, you need to take 
into account the number of notes you want to play on each part as 
well as the number of tones used by the selected patch (p. 102, p. 
118).
It is not possible to make Voice Reserve settings that would 
cause the total of all parts to be greater than 64 voices.
