Steady State Fate Ultra Random Analog

Six flavors of analog randomness in 10hp

10 HP Eurorack module

The Ultra-Random Analog is a comprehensive analog random voltage generator offering six distinct random outputs including stepped, slewed, toggled, fluctuating, and pulsed random signals alongside a vactrol-based integrator. Its musical character is deeply organic and unpredictable, capable of generating everything from slow evolving generative melodies to chaotic audio-rate noise and rhythmic random gate sequences. The module excels at injecting life and variation into patches through its deeply interconnected internal normalization and 1V/Oct tracked clock.
