Sequential Voltage Source

Soundfreak Synthesizer Module

The Soundfreak Sequential Voltage Source is a multi-step sequencer inspired by the classic Buchla Model 123 and 140 architectures. It features eight discrete steps (numbered 1–8), each capable of storing four independent voltages (Rows A–D) via the integrated potentiometer array.

The module offers flexible sequencing modes: it can function as a four-track parallel sequencer (up to 8 steps) or as a chained serial sequencer, providing configurations of up to 16 or 32 steps.

A timing pulse (internal or external) advances the sequencer to the following step. Whenever a step is selected, its LED will light up and its Pulse Output will output a high pulse signal. ​
