Walrus Audio Fundamental Series Ambient Pedal

The Qi is the first creation to emerge from our groundbreaking proprietary digital processing platform, MDSP. Designed in-house by our talented engineering team, MDSP sets a new benchmark for high-fidelity audio and innovative design, delivering decades of inspiration to creators seeking practical yet forward-thinking gear.

At the core of MDSP is the powerful ARM-based Cortex M7 processor, renowned as the highest-performing processor in its class. With a proven history in high-level electronics, the Cortex M7 has been meticulously tailored for advanced audio algorithm processing in the MDSP platform. This unique system integrates a microcontroller and a DSP into a single compact unit, enabling a smaller, modular design that can seamlessly adapt to a wide range of pedal formats.

This modular and "mini" approach empowers Walrus Audio to push the boundaries of audio processing. The enhanced capabilities of Walrus’s MDSP allow for the development and implementation of more sophisticated algorithms than ever before, delivering unparalleled creative possibilities for musicians and audio professionals alike.

The MDSP platform also boasts a superior audio codec, supporting faster sample rates, increased bit depth, greater headroom, and an exceptional signal-to-noise ratio. These enhancements ensure outstanding audio performance, setting a new standard in digital signal processing for the music industry.

The introduction of MDSP reflects Walrus Audio's commitment to providing creators with cutting-edge tools that inspire innovation and creativity. The Fundamental Ambient offers a great entry point into ambient exploration, because vast ambient sounds shouldn’t just be for pricier pedals. The Fundamental Ambient brings expansive pillowy reverb to the Fundamental Series with three atmospheric modes in a compact size. With Ambient’s three reverb algorithms, you can experiment with deep, dark pad-like sounds to AM Radio-like lo-fi sounds with the flip of a switch. Deep – A dark ambient reverb with an added low octave, perfect for creating murky, cavernous sustain or adding a touch of moody atmosphere. Lush – A breathy, expansive reverb featuring ultra-long sustain. Perfect for generating silky pads and immersive soundscapes with every note. Haze – A textured, lo-fi reverb featuring distortion, sample rate reduction, and a resonant bandpass tone control, great for vintage or experimental tones.
