Sound Design and the Four-Layer Morphing Engine

The core of Radiant Decay is a four-layer morphing engine. Each layer has its own sound-shaping controls, including attack, release, offset, pitch and pan. Every layer also has its own arpeggiator and filter, and the filter section offers 39 filter types.

The assignable XY pad lets you move between the four layers in real time. Randomize functions and user sample import make it straightforward to push the sound in unexpected directions, and you can blend your own WAV files with the included material and 24 wavetables.

Presets, Contents and Effects

The instrument ships with more than 150 factory presets, browsable in the Preset Browser. You can save your own patches, export them, or import presets, and a random preset generator can produce new starting points.

The library contains 2,551 stereo 24-bit 48kHz WAV samples, and the full install takes 11.4 GB. The built-in FX rack includes convolution reverb with over 100 custom rooms, halls, chambers and FX spaces, along with a range of DSP effects.
