The Story of UDW-LE

Introducing Ultrasonic Death Whistle Light Edition (UDW-LE): Embark on a sonic journey where whispers of ancient lore harmonize with deep, mysterious undertones. UDW-LE serves as an introduction, offering a small taste of the rare and unique sounds that characterize our full UDW and UDW-X instruments. This edition previews a small glimpse of the expansive creative potential driven by our MNDALA 2 acoustic synthesis engine.

Captured by our founder, award-winning composer & multi-instrumentalist Brian D’Oliveira, UDW-LE provides a window into our curated collection of unique pre-Colombian Aztec Death Whistles. Researched and handcrafted by Brian over several years, these sounds have been pivotal in the soundtracks of numerous renowned AAA video games he has contributed to.

UDW-LE features a video-game audio-inspired interactive scene, enabling non-linear, multidimensional control and patch creation, facilitating intuitive and seamless musical expression.

Each death whistle tells its own tale, with their names embodying distinct personalities. Meticulously handcrafted, every whistle produces a unique sound, its own signature. The sample maps capture these individual tones, standing by to elevate and enrich your musical compositions.

Available only until Nov 15th, 2023. Get it now!
