The higher the sampling frequency is, the closer to the
original analog signal the waveform in memory will
be.
Each level is read, and converted into digital data. The
accuracy at this time is determined by the bit resolu-
tion. This process converts an analog signal with infi-
nite resolution into a digital signal with finite
resolution. With 16 bit resolution, each level is indi-
cated in 65,536 steps (the sixteenth power of two).
The greater the bit resolution is, the closer to the origi-
nal analog signal the waveform in memory will be.
48 kHz 16 bit sampling is the same quality as in audio
devices such as DAT. A CD uses 44.1 kHz 16 bit sam-
pling, which is a slightly lower sampling frequency.
Samples and Multisamples
Samples
The data that is recorded (sampled) into internal mem-
ory or loaded from a file is referred to as a sample or
sample file. Samples consist of the actual waveform
data, and parameters that specify how the data will be
played back, such as Start, Loop Start, and End
Address. Samples can be used by multisamples and
drum kits.
The TRITON-Rack can hold a maximum of 4,000 sam-
ples in its internal memory.
The TRITON-Rack can share a single waveform
among multiple samples. This allows you to create
multiple samples with different playback
addresses from the same waveform without wast-
ing internal memory. For example, suppose that
you have waveform data that records a voice say-
ing "One-Two-Three." This single piece of wave-
form data could be shared by three samples, with
the playback of sample A producing "One-Two-
Three," sample B producing "One-Two," and sam-
ple C producing "Two-Three." ( PG p.80).
Multisamples
A multisample consists of settings that make one or
more samples sound in different areas of the keyboard.
A multisample consist of between one and 128
"indexes." Each index contains parameters that specify
the sample that will playback, the zone for which it will
playback, the original pitch key, the playback pitch,
and level etc.
Using multisamples
When sampling an instrument that is able to produce a
wide range of pitches, such as a piano, recording just
one sample and using it (playing it back) over the
entire pitch range will not produce a natural-sounding
result. By using a multisample you can record separate
samples for each pitch range, and assign these samples
to their respective pitch ranges to avoid any unnatural
sounds during playback. For example, you might
record one sample per octave, and assign each of these
samples to an index (keyboard area). All of the instru-
mental sounds in the TRITON-Rack's internal preset
ROM multisamples are constructed in this way.
By assigning multiple samples such as phrase samples
or rhythm loops to a multisample and arranging them
across the keyboard, you can play multiple samples
simultaneously. Since a different phrase could be
assigned to each key, you can perform just as though
you were using a pad-type sampler. Alternatively,
these samples could be assigned at one-octave inter-
vals, and played as phrase variations with different
playback pitches.
The TRITON-Rack can hold a maximum of 1,000 multi-
samples in its internal memory.
A multisample can be selected as the oscillator for a
program, and played as a program. In a combination,
they can be combined with preset programs, and used
in a multi. They can be used with the arpeggiator to
produce interesting results (for example, by using the
arpeggiator to automatically play sound effects or spo-
ken samples).
