MAX FOR LIVE | VOID ECOSYSTEM > MIDI BEAT REPEAT
Probabilistic Beat-Repeat & Ratchet Engine. A high-performance MIDI device powered by a custom C external, designed to transform any incoming note into evolving rhythmic patterns with musical precision and probabilistic depth.
1. The Canvas: 32-Step Probability Heatmap
Driven by a custom C engine, each of the 8 pitch lanes carries a 32-step density field — not a step sequencer, but a probability map read continuously against the phasor timeline.
Column Brightness: The intensity of each column equals the likelihood of a repeat firing at that phase position. Draw curves, create gradients, or fill with structured randomness. All Mode: A single full-height canvas drives all incoming notes from one unified probability field. Selected Mode: Each pitch is routed to its own independent lane, enabling per-note rhythmic behavior within a single device instance. Randomize: Zone-based binary fill generates rhythmically coherent density patterns with a single click. Each press creates a new seed.
2. The Engine: Subdivision Variation
Each repeat is anchored to its theoretical grid position, with variation adding a controlled offset drawn from a discrete set of musical subdivisions.
Grid: Base repeat interval synced to Live's tempo. Supports standard note values and triplets. Variation: At 0%, all repeats land exactly on the grid. Higher values allow each repeat to independently draw from ÷4, ÷2, ×1, ×2, or ×4 subdivisions — creating rhythmic bursts and unexpected slowdowns while preserving the musical pulse. Each Mode: Every repeat draws its own subdivision independently for maximum rhythmic chaos. First Mode: Only the first repeat is shifted; subsequent repeats lock back to the grid for a controlled pickup effect. Randomize Count: Instead of a fixed repeat count, the engine draws a random value between 1 and the set maximum for each trigger event.
3. The Decay: Velocity Attenuation
The repeat chain follows a per-event exponential decay curve driven by the original note's velocity.
Attenuation: Each successive repeat loses velocity following a mathematically defined curve. The harder the incoming hit, the more dramatic the fade across the chain. Visual Feedback: The engine display shows bar height proportional to velocity ratio, with a connecting curve tracing the decay envelope across all repeats.
4. The HUD: Three-Layer Live Feedback
The interface provides real-time causality — you see exactly what happened and why, at every moment.
Blue (left edge): Dry note arrived on this lane. Always fires, regardless of probability outcome. Lime (left edge): Ratchet triggered — the probability gate passed and repeats were scheduled. Teal (right edge): Each individual scheduled repeat fires. The tac-tac-tac made visible.
