Tone generators and oscillators

The oscillators of the TRITON STUDIO are sounded by
two Tone Generators.
Each tone generator is connected to the various PCM
memories as shown in the diagram below.
Tone Generator 1
• ROM: Internal PCM ROM (32 Mbytes)
• RAM: User sample memory (16 Mbytes, expandable
to a maximum of 96 Mbytes)
Tone Generator 2
• Piano: Internal Piano PCM ROM (16 Mbytes)
• EXB-PCM: Expansion PCM ROM (16 Mbytes each;
maximum of 7 boards totaling 112 Mbytes)
PCM memory
ROM (Internal PCM ROM) 32 Mbytes
RAM 96 Mbytes*
(User sample memory)
* = Expandable to a maximum.
Factory settings is 16 Mbytes
Tone Generator 1
Maximum 60 oscillators
Total maximum 120 oscillators
Each tone generator is able to simultaneously sound up to
60 oscillators (i.e., to play the PCM data connected to that
tone generator). Together, the two tone generators are able
to sound up to 120 oscillators.
However, it is not possible, for example, to simulta-
neously play 61 or more oscillators from only the internal
PCM ROM.
PCM memory
Piano (Internal Piano PCM ROM) 16 Mbytes
EXB-PCM (Expansion PCM ROM Slot1) 16 Mbytes
EXB-PCM (Expansion PCM ROM Slot2) 16 Mbytes
EXB-PCM (Expansion PCM ROM Slot3) 16 Mbytes
EXB-PCM (Expansion PCM ROM Slot4)16 Mbytes
EXB-PCM (Expansion PCM ROM Slot5)16 Mbytes
EXB-PCM (Expansion PCM ROM Slot6)16 Mbytes
EXB-PCM (Expansion PCM ROM Slot7)16 Mbytes
Tone Generator 2
Maximum 60 oscillators

Number of voices in each mode

The maximum number of voices that can be played simul-
taneously will depend on the oscillator mode of the pro-
gram.
• For a Single/Drum-mode program, 1 oscillator = 1
voice
• For a Double-mode program, 2 oscillators = 1 voice
Program mode
Single/Drum-mode
Normally, 60 voices can be used.
However a maximum of 120 voices will be available if, for
example, ROM or RAM is used for the High MS, and
Piano or EXB-PCM is used for the Low MS, and you use
velocity switching to play the two tone generators.
Double mode
Normally, 30 voices can be used.
However if OSC1 is sounded by one tone generator and
OSC2 is sounded by the other tone generator (e.g.,
OSC1=ROM, OSC2=Piano), a maximum of 60 voices can
be used. If OSC1 and OSC2 use one tone generator (e.g.,
OSC1=ROM, OSC2=ROM), then a maximum of 30 voices
can be used.
This can also be increased by velocity switch and velocity
zone settings.
Combination, Sequencer, and Song Play modes
Depending on the oscillator mode of the programs you
are using, the maximum number will vary between 60
voices and 120 voices.
(Example)
For single-mode programs that use ROM or RAM, a total
maximum of 60 voices
For single-mode programs that use Piano or EXB-PCM, a
total maximum of 60 voices
Total 120 voices
For double-mode programs that use ROM or RAM, a total
maximum of 30 voices
For double-mode programs that use Piano or EXB-PCM, a
total maximum of 30 voices
Total 60 voices
Sampling mode
Tone generator 1 is always used in Sampling mode.
Mono samples/multisamples
60 voices.
Stereo samples/multisamples
30 voices.
