BOOL is a compact, CV-controlled logic utility for turning clocks, gates and modulation signals into new rhythmic patterns.

Select AND, OR, XOR, NAND, NOR or XNOR directly from six dedicated mode buttons. Independent THR A and THR B controls let each input respond at a different voltage, with dedicated CV inputs for moving those thresholds as part of a patch. Fixed Schmitt hysteresis keeps comparisons stable near the threshold.

GATE provides the selected Boolean result at 0/+5 V. TRIG creates a pulse on each rising edge of that result, with a 1–100 ms PULSE control and dedicated TIME CV for expressive pulse-width modulation. Separate output activity LEDs make short events easy to see.

Features • Six directly selectable logic functions: AND, OR, XOR, NAND, NOR and XNOR • Independent −5 to +5 V thresholds with dedicated CV inputs • 0.2 V Schmitt hysteresis • 0/+5 V GATE and rising-edge TRIG outputs • Pulse width from 1 to 100 ms, with exponential TIME CV modulation • Separate gate and trigger activity indicators • 12 HP panel

Patch two clocks into A and B to create coincidences with AND, combine events with OR, or use XOR to pass events that occur on only one input. Modulate a threshold with an LFO to change a gate pattern over time, or use TIME CV to vary trigger width.

Unpatched operands are treated as false. Inverted functions can therefore produce a high GATE with no input patched. TRIG does not emit a pulse merely because a patch loads with its result already high.
