Aloysius Eurorack Trapezoid Generator Module

Expert Sleepers Aloysius: Analog Trapezoid Powerhouse

Aloysius is a characterful function generator that recreates the distinctive AHDW (Attack/Hold/Decay/Wait) envelope popularized by vintage British synthesizers.By adding a "Wait" stage to the traditional envelope cycle, it allows for rhythmic gaps in modulation that are perfect for sparse, pulsing textures.When set to Auto-mode, it becomes a versatile analog LFO where every stage can be manipulated via external CV.Because the circuit is entirely analog with discrete logic, the response is instantaneous and smooth, making it a "must-have" for users who value organic, non-quantized modulation.

Key Features:

• Classic Trapezoid Configuration: Authentic AHDW stages for unique envelope shaping.

• Independent Shape Control: Continuously variable Attack and Decay curves (Exponential to Logarithmic).

• Self-Oscillation Mode: Transforms into a complex LFO with the flick of a switch.

• Comprehensive CV I/O: Dedicated CV inputs for every envelope stage.

• Discrete Analog Design: No microcontrollers or digital artifacts for a pure sonic path.
