Description
The Tiptop Audio Buchla 245t Sequential Voltage Source is a symphony of innovation and tradition, merging the iconic design of Buchla with modern Eurorack compatibility. This module stands out as a beacon for synthesists who crave the depth and versatility of West Coast synthesis. Engineered in collaboration with Buchla, the 245t is not merely a nod to its legendary predecessors but a faithful recreation that brings the Buchla ethos to the modular world.
The heart of the Buchla 245t is its dual-functionality, featuring both a Pulser and Stored Voltage Stages. These sections work in tandem to provide a richly textured sonic experience, allowing users to store and manipulate control voltages with precision. The Pulser's internal clock offers adjustable pulse width and tempo, providing rhythmic complexity that can be seamlessly integrated into any modular setup. With 4 rows and 5 steps, each capable of storing 4 voltage values, this module offers unparalleled control over your soundscapes.
Designed to be both user-friendly and deeply customizable, the 245t's interface includes start and stop buttons with trigger inputs, CV inputs for pulse width and tempo, and direct step selection. Its compact 30HP size ensures it fits snugly into any Eurorack system, offering the kind of flexibility that modular enthusiasts dream of.
