Description

Mooloolaba Music is excited to announce that the Walrus Audio Qi Etherealizer is now available in our inventory.

The Qi Etherealizer, which is pronounced “chee ethereal-izer,” serves as a multi-effects pedal developed in collaboration with Yvette Young. This unit integrates Chorus, Delay, Granular effects, and Reverb to provide a creative playground for those focused on atmospheric exploration.

Inspired by Yvette Young—who is celebrated for her leadership of the math rock group Covet, her fondness for guitar pedals, and her pioneering fingerstyle technique—the Qi embodies her method of crafting lush, developing soundscapes. The name itself references the life energy present in all living things, and the pedal is engineered to provide dynamic layers, expansive atmospheres, and rich textures. By merging Yvette’s artistic perspective with modern design, the Qi provides access to otherworldly and immersive sounds.

Within a stereo field, the Qi enables you to combine and adjust chorus, delay, and grain effects, running them in either series or parallel to build a unique universe of sonic possibilities. You can toggle settings instantly by simultaneously depressing the Bypass and Freeze stomp switches, which also allows you to bypass the grain, delay, and chorus controls or save your own presets. Whether you prefer a standard chorus enhanced with slight delay or want the Qi to envelop your sound in lush, glitchy, and unexplainable ambient washes, this pedal is designed to revitalize your personal style.

The Qi represents the debut product from our proprietary digital processing platform, MDSP. This platform was created in-house by our engineering team to establish a new standard for innovative design and high-fidelity audio, offering a long-term source of inspiration for creators in need of forward-thinking and practical equipment.

At the heart of the MDSP platform lies the ARM-based Cortex M7, a high-performance processor recognized as the leader in its class. Because of its established success in advanced electronics, the Cortex M7 has been specifically adapted to process sophisticated audio algorithms for our platform. By integrating a DSP and a microcontroller into one compact unit, this system enables a modular, small-scale design that integrates easily into various pedal formats.

This mini, modular design philosophy allows Walrus Audio to expand the limits of what is possible in audio processing. Because the MDSP platform offers enhanced capabilities, we are able to develop and run more complex algorithms than previously possible, which opens up exceptional creative potential for audio professionals and musicians.

Furthermore, the MDSP platform utilizes a premium audio codec that supports higher bit depth, faster sample rates, an improved signal-to-noise ratio, and greater headroom. These features guarantee superior audio quality, establishing a new benchmark for digital signal processing across the music industry. The launch of MDSP highlights the dedication of Walrus Audio to equipping creators with modern tools that foster creativity and innovation.

Features

Global Controls

Space KnobSpace adds a delightfully charming reverb to your affected signal. Use this knob to modify the mix and decay of the reverb. Go from smaller room sounds to a huge, diffused ambient reverb at maximum settings. It’s lush and complimentary, and adding it in with the other effects will put you squarely in dreamscape territory.

Tone Knob:  The Tone parameter controls the cutoff of a synth-style resonant low pass filter, allowing you to shape the tone of the effect output.

Series and ParallelIn series, effects will feed into each other in the order of Chorus > Delay > Grain > Output.

In parallel, all of the effect outputs on Chorus, Delay, and Grain are summed together and do not feed into each other. The top row of knobs will act as level controls, and the user can control the level of each effect.

The Mix/Dry parameter controls the mix of wet and dry signal in series mode and dry level in parallel mode.

Grain Controls

The featured Grain effect features two ‘flavors’ of operation:

Grain Cloud: This mode triggers small samples (grains) randomly from your playing, which gives you unpredictable, yet charming glitchy texture for your sound. The X knob controls the length of time between grains, so you can go from dense clusters to sparse accents.

Phrase Sample: This mode triggers grains rhythmically from your playing. Initial peaks in your playing are detected and grains are played back starting at these peaks, creating a rhythmic and intentional effect. The X knob controls the tempo at which the samples will be played back. Turning the X knob to the minimum position will sync the Phrase Sample time to the Delay time so that repeated grains are in time with the Delay repeats.

The Grain effect also features 5 playback modes that dictate different ways the grain samples are projected.

• x1: Normal

• x2: Double-speed and +1 octave

• x.5:  Half-speed and -1 octave

• REV: Reverse playback

• RNDM: Randomized combination of the previous four modes.

Delay Controls

The delay effect is a full, clean digital delay that offers repeats for up to two seconds. Use the time knob to control the time between delays as well as the feedback knob to control the amount of delays. The TAP/OSC switch on the bottom right of the pedal can also be used to control the delay effect via tap tempo, or when held down will ramp up the feedback and cause the delay to oscillate.

Subdivisions

Delay trails can be projected in three subdivision modes:

  • Quarter Note
  • Dotted Eighth Note
  • Eighth Note

Chorus Controls

The Chorus effect offers two modes:

Tri Chorus: A multi-dimensional chorus favorite. Lush, complex, modulated sounds combining three voices for a full, vibrant sound. 

Stereo Chorus: This mode is a classic chorus effect but with the modulation of the chorus being offset 180 degrees to the right channel to achieve the stereo width effect.
