DLS Level 1 and Level 2

Beginning with the DirectX 8.0 release of DirectMusic Producer, you can design DLS collections to take full advantage of the Downloadable Sounds Level 2 standard. Previous releases of DirectMusic Producer included support only for Level 1.

DLS Level 2 provides several new options for designing DLS instruments:

In addition to mono wave files, you can insert stereo waves into the Waves folder of a DLS collection, and integrate them into DLS 2 instruments.

DLS Level 2 allows all DLS instruments to have a separate region, based on its own wave sample, for each of the 128 MIDI notes. DLS Level 1 instruments have a maximum of 16 regions.

DLS Level 2 enables each MIDI note to derive from multiple waves. Waves can be layered to achieve a richer timbre, or can be used singly at different note velocities.

The Low Frequency Oscillator capabilities of the articulation are doubled, from one to two LFO controls. The first is designated for volume while the second is for pitch or filter modulation.

DLS Level 1 supported envelopes with four segments for volume and pitch articulation: Attack, Decay, Sustain and Release. Level 2 adds Delay and Hold.

Sounds can be tailored to the features available on the synthesizer.
