The Magnetic Freak Boolean Logic Latched is a compact, Buchla-compatible, fully analogue logic module designed for generating complex, clock-driven rhythmic sequences, capable of operating up to audio rates with no latency.
This precision-built module provides a dual-stage Boolean logic system allowing users to manipulate simple clock signals into intricate rhythmic patterns ideal for IDM (Intelligent Dance Music) and experimental sound design. The module offers seven logic operations including Off, AND, NOR, XOR, OR, NAND, giving complete control over gate signal combinations. Each of the two logic inputs labelled A and B feeds into a rotary selector that determines the operation, while the results output in real-time via the red "Direct" connector. The system can cascade signals, using the outputs of the first two logic stages as inputs for a third-level operation, enabling even more complex logic structures.
The latching function samples and holds the status of all logic outputs upon receiving a trigger at the violet "Latch" input or via the manual push-button. This allows precise resynchronisation of unsynchronised or random sources, locking rhythmic variations in place until the next trigger arrives. This feature works in tandem with the real-time outputs, providing both immediate and held signal states simultaneously.
An integrated clock divider outputs five subdivisions of the input clock (1/2, 1/3, 1/4, 1/6, 1/8), providing stable timing signals that serve as reliable sources for logic operations. This ensures users can derive multiple, synchronised rhythmic signals from a single clock source. For greater patching efficiency, the module includes zones for banana bridges, reducing cable clutter and facilitating compact signal routing.
Owing to its analogue circuitry, the BOOLEAN LOGIC LATCHED operates reliably at high frequencies, supporting audio-rate signals up to 20 kHz. This enables its use beyond traditional rhythmic applications, offering possibilities for complex modulation or audio-rate experimentation.
The unit fits a standard 1U format with slotted 3.2 mm fixation holes and requires a minimum installation depth of 35 mm. The module consumes 50 mA at +15V and processes gate inputs ranging from 0V to 10V, detecting signals from 3V upwards. It emits 13V gate pulses, with each connection point featuring an LED for clear visual feedback on timing and signal status.
The Boolean Logic Latched excels in building IDM-style rhythms from minimal inputs, resynchronising multiple LFOs, and introducing evolving, organic variations when fed with unsynchronised clocks. Its ability to operate at audio rates extends its usefulness to experimental sound design and modulation beyond traditional rhythm generation.
