What it is and what it was built for
A Eurorack module for generating structured, responsive randomness in timing and control voltage. Built for live modulation, generative composition, and breaking out of repetitive patterns—not for sound generation or sequencing.
How it works, in terms a player would use
It generates jittered clocks and random CVs in three parallel streams. The t section splits a master clock into three gate outputs. X 1–3 each output independent random voltages, clocked either by individual t outputs or a shared external clock. Y delivers a slow, smooth, full-range voltage unaffected by DEJA VU. DEJA VU toggles between reusing past values and sampling fresh hardware randomness. STEPS quantizes incoming CV by progressively eliminating notes from a chromatic scale based on occurrence frequency. Six C-rooted scale memories are selected via LED feedback and button presses.
What it does better than anything else
It links timing, pitch, and memory in one module better than any other Eurorack device. Its DEJA VU section uniquely ties reuse probability to live performance—past choices directly shape future ones. Its STEPS quantizer learns from your input instead of imposing fixed scales. Its t section delivers three interlocking, jittered gate streams from a single source—no routing required.
What it does badly
It does not generate audio. It cannot store or recall user sequences beyond six scale slots. It offers no MIDI, no USB, no patch memory, no visual feedback beyond LEDs. Its randomness is not tunable in real time without holding buttons and adjusting parameters mid-flow. It gives no indication of internal state beyond blinking LED colour and rate.
What people made with it
People used it to drive drum machines, modulate filter cutoffs, trigger melodic phrases, and create evolving rhythmic textures. Its ability to learn scales from incoming CV made it central to live-keyboard improvisation and modular jamming where tonal coherence emerged from interaction, not pre-programming.
Who should use it, and who should not
Modular players who treat randomness as a collaborator—not a substitute for intention. Those who want CV that adapts, remembers, and misbehaves in musically useful ways. Not for beginners seeking immediate melodic results, or for users needing recall, sync, or audio output.
Is it worth your time
Yes—if you need generative timing and CV that responds to your playing, not just random noise. It demands hands-on engagement: no presets, no menus, no screen. Its value lies in how it interrupts habit and forces new decisions—not in stability or recall.
