UZZ - VCV Rack
16-step sequencer for VCV Rack 2.x. Precise timing, structured improvisation and total modular flexibility. Each step has Pitch, Octave, Duration, Mod1/Mod2 and Prob/Pulse. Ten direction modes, semitone accumulator and global multiplicative probability.
From Max for Live to VCV Rack
UZZ was born as a Max for Live device. This port to VCV Rack 2.x preserves the original philosophy: precise timing, structured improvisation and total modular flexibility. Designed for live performance and studio, it prioritizes editing speed and immediate musicality.
Each step has its own Pitch, Octave, Duration relative to tempo, Mod1, Mod2 and a bipolar Prob/Pulse knob. The active window is configurable (Start + number of steps) with wrap-around. Semitone accumulator, global multiplicative probability and polyphonic gate output complete the module.
Step modes
Fires the step normally.
Advances but generates no gate or pitch.
Skips the step without consuming clock time.
Adds semitones to the pitch accumulator.
Subtracts semitones from the pitch accumulator.
Multiplies the gate according to the Prob/Pulse knob.
Gate active while clock pulse arrives.
Holds the pitch and gate of the previous step.
Per-step parameters
Pitch 0–12 semitones. Octave shift −2 to +2.
Relative to tempo. Controls the articulation of each note.
Two independent CV outputs. Context menu: unipolar (0–10 V) or bipolar (±5 V).
Bipolar knob: left side = gate probability; right side = pulse multiplier.
10 direction modes
Advances step by step.
Goes backwards step by step.
Back and forth without repeating endpoints.
Back and forth repeating endpoints.
Random step on each pulse.
Wanders without losing the beat.
Alternates even and odd steps.
Defined jumps between steps.
Advances from the edges toward the center.
Advances from the center toward the edges.
Global control
Row Randomize & Shift
Row Randomize
Button and CV input to re-randomize each row: Pitch, Oct, Mode, Dur, Mod1, Mod2, Prob.
Row Shift ↑/↓
Arrows to shift all values in each row, including the Prob/Pulse row.
