Hydra is the multi-armed DSP creature tapping its tentacles into a buffered delay line and creating a range of multi-tap delay rhythmic and spatial effects. The Spread parameter sweeping through rhythmic variations allowing some of the programs bridge the gap between single delays and reverbs by using diffusion while others use taps to create rhythmic patterns.
The basic Hydra algorithm sums the inputs to mono and writes the signal to a single delay line. Multiple output taps are taken from the delay line and spread across the stereo outputs. Each program adds additional features like panning, filtering, pitch shifting and/or diffusion to create a unique Z-DSP Hydra experience. The last two programs add external Clock input for more precise sync to the beat.
Spirals is a pitch and multi-tap delay card for the Z-DSP. This card uses numerous multi-tap delay techniques in combination with dual pitch shifters to create a wide range of harmonizing choruses, echo and harmonic reverb sounds. Programs on this card derive from the complex algorithms found on high-end studio effects processors, which, while powerful, have a complex editing process. On the Z-DSP all of the power of the internal code is controlled by three simple adjustments for sculpting the sound—making the experience more about performance and live tweaking rather than navigating through dozens of menu pages.
