Buchla 259e Twisted Waveform Generator

The Buchla 259e Twisted Waveform Generator is a unique and powerful analog synthesizer module designed by Don Buchla. It is a complex oscillator that produces a wide range of complex waveforms, including sine, sawtooth, triangle, and pulse waves. It has been used by a variety of artists, including Aphex Twin, Autechre, and Squarepusher.

The 259e Twisted Waveform Generator works by combining two oscillators with different waveforms and then modulating them with a variety of parameters. This allows for a wide range of complex waveforms to be created. It also features a voltage-controlled filter, an envelope generator, and a voltage-controlled amplifier. Additionally, it has a built-in noise generator and a variety of modulation sources, including an LFO, an envelope follower, and a sample-and-hold circuit.
