Wave Packets is the first Eurorack module from design team Auza. 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 the four primary dimensions of time, depth, frequency and wave shape. With five distinct unipolar and bipolar outputs, an infinite and unique range of shapes and sounds can be produced: an envelope growing from nothing to wild oscillation, a punchy bass drum with monstrous pitch decay, a ping-multiplied burst generator, an amplitude-varying LFO or timbre-morphing oscillator. Our novel model combines frequency-dynamic oscillation and function generation for crafting modulation and audio signals that fuel creativity. What emerges is a highly versatile production tool kit in 16HP.

The module 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 summarised as: the pure contour, the unipolar wave, the resonating contour, the capsulated oscillator and the pure oscillator. As the outputs are simultaneously utilisable 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 utilising multiple outputs at the same time, Wave Packets can act as a hub for orchestrating movement across new and exciting patches.
