Stereo Waves

DirectMusic Producer supports the use of both mono and stereo wave files. You can insert both types of waves into the project tree, and open them with Wave Editor, or drag them into the Waves folder of a DLS collection for use when designing DLS instruments. You can also insert both types of waves into the Wave Track of a segment.

The icon of the wave shows whether it is mono or stereo. The following figure shows a DLS collection containing the icons of four mono waves and one stereo wave, Bright Trumpet2.

Mono and stereo waves

When you open a stereo wave in Wave Editor, both the left and right channels of the wave are displayed in the editing window. The following figure shows the Bright Trumpet2 stereo wave, with the left channel on top.

Stereo wave in Wave Editor

Stereo waves are edited just as if they were a single wave. You cannot edit the two channels independently.

DLS Designer divides stereo waves into two separate waveforms for the left and right channels. For example, a stereo wave in the Waves folder of an instrument called "Applause" is available for selection in a region as either the stereo version, "Applause", or as either of the channels, "Applause (Left)" and "Applause (Right)".

Because multiple layers are supported only by DLS Level 2 synthesizers, only a single channel is heard when the instrument is played on a DLS1 synthesizer. To support both levels of synthesizer, place a mono version of the wave in the bottom layer and the stereo version in another layer. Use conditions to play the first layer only on DLS1 and the next two layers only on DLS2. For more information, see Conditional Regions and Articulations.
