Auza Wave Packets ‘A Versatile New Wave Source’ For Eurorack Modular Synths

Audio design duo Auza has introduced their first Eurorack module, Wave Packets, which they describe as “a highly versatile production tool kit in 16HP”.

Capable of generating complex envelopes, modulation signals and audio, the module allows you to sculpt your sound by producing time-limited signals or “wave packets”.

Each wave packet is determined in four primary dimensions: time, depth, frequency and wave shape. With five distinct unipolar and bipolar outputs, a wide range of shapes and sounds can be produced: an envelope growing from nothing to wild oscillation, a punchy bass drum, a ping-multiplied burst generator, an amplitude-varying LFO or timbre-morphing oscillator.

Wave Packets can operate in three excitation modes: trigger, gate, and cycle.

Once animated, the 3 depth sliders sculpt the wave packet’s overall contours, whilst the wave shape, glide and 3 frequency controls determine its oscillations through time.

The five outputs map five distinct interactions between the contour function and oscillations. These can be summarized as: the pure contour, the unipolar wave, the resonating contour, the capsulated oscillator and the pure oscillator.

The module is fully self-patchable, allowing for new wave packet models to be achieved. Examples include patching a unipolar output into wave shape CV for morphing across timbres, or patching a bipolar output into depth CV to achieve audio-rate modulation. By using multiple outputs at the same time, Wave Packets can also act as a hub for orchestrating movement across patches.
