Buchla 250e Dual Arbitrary Function Generator
A dual-channel modular synthesizer module capable of complex voltage control, sequencing, and modulation.
Overview
The Buchla 250e Dual Arbitrary Function Generator is a modular electronic music module designed and manufactured by Buchla. It features two independent channels, each with 16 programmable stages, allowing for precise control over time and voltage. The module functions as a complex envelope generator, a dual 16-stage sequencer, and a modulation source, either individually or in combination. Each stage can be set as a rise or fall segment with independent adjustment of time and voltage level, and the entire system supports voltage control over stage time, voltage level, and curve shape.
The 250e can be clocked internally or externally and offers multiple run modes including run once, loop, or be triggered. Its flexibility makes it a powerful tool within Buchla's modular ecosystem for generating evolving control signals and intricate sequences.
