Description
The Stepper Acid is a 16-step Eurorack sequencer built for speed, performance, and full-blown tweakability. With x0x-inspired controls, per-step probability, glide, ratchets, and swing, it nails that hands-on acid sequencing feel—no menus, no shift layers, just instant access to everything. Patterns can be chained, transposed, reversed, randomised, or modulated on the fly.
LED sliders give you real-time feedback, while the onboard clock and CV control keep it locked to your system. Whether you’re after classic acid lines or unpredictable rhythmic chaos, Stepper Acid delivers—fast, fluid, and fierce.
The Stepper Acid features a 16-step CV/gate sequencer with 64 pattern slots, per-step glide, ratchets, probability, and direction modes including reverse, random, and pendulum. It offers CV transpose, an onboard quantiser with 0–5V or 0–10V output range, and an internal clock with tap tempo plus clock and reset I/O. Compact and skiff-friendly at 34HP wide and 40mm deep.
Includes ribbon cable.
