Buchla 251e Quad Sequential Voltage Source

The Buchla 251e Quad Sequential Voltage Source is a voltage-controlled analog sequencer designed by Don Buchla in the 1970s. It is a four-channel voltage-controlled analog sequencer that can be used to generate complex patterns of voltage-controlled signals. It has four independent channels, each with its own voltage-controlled clock, reset, and direction controls. Each channel can be set to a different length and can be used to generate a variety of patterns. It also has a built-in voltage-controlled low-pass filter and a voltage-controlled amplifier.

The Buchla 251e has been used by a variety of musicians, including Aphex Twin, Autechre, and Boards of Canada. It is a popular choice for creating complex and evolving patterns of sound. It is also used in modular synthesizers and in live performance.
