Scratch the surface of any synthesizer, and you’ll find the heritage of a few great brands. Buchla has been responsible for some of the most innovative, creative, and sonically spectacular electronic musical equipment ever made, and we’re proud to have such a legendary name in Softube Modular.

In addition to our previously released 259e Twisted Waveform Generator, take advantage of the myriad spectral processing capabilities of the big friendly filter bank, the new 296e Spectral Processor, the only software version of this module officially licensed by Buchla U.S.A.

With the 259e, the answer is - pretty twisted. A coveted dual oscillator module now available for Softube Modular, Buchla 259e Twisted Waveform Generator is the first-ever officially licensed plug-in version of a Buchla product. While the unit can be used for traditional synth patches, its unusual inner workings makes Buchla 259e excel at metallic, cold, harsh, digital and screeching sounds.

Ever since the low pass gate was invented by Don Buchla for his 200 series instruments in the early 1970s, low pass gates have been heralded for their ability to add a lifelike and organic response to modular synth patches. They work by applying an envelope to a low pass filter with its 0-voltage cutoff frequency way below audible range, so when the envelope is down, the 'gate' is closed. As a note decays, its high frequencies die soonest – just like most acoustic sounds.
