Media mode information

Chunks that are supported

When loading

AIFF files

When data is loaded into the TRITON Le, the following four chunks are referenced: Common chunk, Sound Data chunk, Marker chunk, and Instrument chunk. Other chunks are ignored.

Restrictions on the parameters in each chunk are described below.

Common chunk

Only one (mono) or two (stereo) channels are supported. Sample sizes of 1–16 bits are supported. If the sample data is 8 bits or less, it will be loaded as 16 bit data with the lower 8 bits always at 0.

Sound Data chunk

Offset and block size are ignored. (Block-Aligning Sound Data is not supported.)

Marker chunk

Up to eight markers are supported. The ninth and subse- quent markers will be ignored.

Instrument chunk

If the loop play mode is ForwardBackwardLooping, this will be handled as ForwardLooping.

baseNote, detune, lowNote, highNote, lowVelocity, highVe- locity, gain, and releaseLoop will be ignored.

WAVE files

When loading, the TRITON Le references the Format Chunk, Sample Chunk, and Wave Data. Limitations are dis- cussed below.

Format chunk

Standard PCM format is the only format category that is supported.

Only one (mono) or two (stereo) channels are supported. Sample sizes of 1–16 bits are supported. If the sample data is 8 bits or less, it will be loaded as 16 bit data with the lower 8 bits always at 0.

Sample Chunk

Only the loop data is referenced. If there is multiple loop data, the loop with the greatest number of loop playback times (Play Count) will be used. Even if the Type is Alternat- ing or Backward, it will be handled as Forward Loop.

Wave data

The Wave List chunk is not supported.

When exporting

AIFF files

When exporting, the TRITON Le will use the Common Chunk, Sound Data Chunk, Marker Chunk, and Instrument Chunk.

Limitations on the parameters within each chunk are dis- cussed below.

Common Chunk

The number of channels is fixed at 1 (mono).

The sample size is fixed at 16 bits.

Marker Chunk

Two markers are used as Loop Start Address and End Address respectively.

Instrument Chunk

The loop play mode is fixed at Forward Looping. Zone data of the multisamples will not be exported.

WAVE files

When exporting, the TRITON Le will use the Format Chunk, Sample Chunk, and Wave Data. Restrictions are given below.

Format Chunk

The format category is fixed at standard PCM format. The number of channels is fixed at 1 (mono).

The sample size is fixed at 16 bits.

Sample Chunk

The Type is fixed at Forward Loop.

Zone data of the multisamples will not be exported.
