The “fixed intervals” mentioned above are generally expressed as the “sampling frequency.” 48 kHz (kilo- hertz) means that sampling is performed 48,000 times each second, and that the interval is 1 (second)/48,000 (times) = approximately 0.00002083 (seconds) = approximately 0.02083 mS (millisecond).

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. The infinite number of levels in the analog signal are converted into digital data with a finite number of levels. With 16 bit resolution, each level is indicated 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 can hold a maximum of 4,000 samples in its internal memory.

The TRITON can share a single waveform among multiple samples. This allows you to create multi- ple samples with different playback addresses from the same waveform without wasting internal memory. For example, suppose that you have waveform data that records a voice saying “One- Two-Three.” This single piece of waveform data could be shared by three samples, with the play- back of sample A producing “One-Two-Three,” sample B producing “One-Two,” and sample C producing “Two-Three.” Refer to “Copy Sample” (p.83) in the Parameter Guide.

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 and assigning a sepa- rately recorded sample to each portion of the pitch range, you can produce a more natural sound. For example, you might record one sample per octave, and assign each of these samples to an index (keyboard area). All of the instrumental sounds in the TRITON’s internal preset ROM multisamples are constructed in this way.

You can use a multisample to arrange multiple phrase samples or rhythm loops across the keyboard, and play two or more 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 intervals, and played as phrase variations with different playback pitches.

The TRITON can hold a maximum of 1,000 multisam- ples 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 song. 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).
