Linköping, Sweden (September 28, 2017)—Softube is touting the new Buchla 259e Twisted Waveform Generator for its popular virtual Eurorack synth called Modular. A dual oscillator, the Buchla 259e module is available for $99 with an introductory price of $79 until October 31, 2017.
The Buchla 259e Twisted Waveform Generator plug-in for Modular features all the digital waveshaping, aliasing noise and fold over frequencies of the original hardware it was modeled upon.
The 259e consists of two separate oscillators—Principal and Modulation—where Modulation can be used either to modulate the Principal oscillator or as a separate generator of audible notes.
“The sine wave generated by the Principal oscillator is simultaneously applied to two of the eight available waveshape tables,” explains Softube promotional materials. “A morph voltage pans between the two tables and a warp voltage varies the amplitude of the sinusoidal (driving) waveform. Both these functions can be modulated by the Modulation oscillator. Three of the waveshape tables are actually not tables in the classical sense; they are simply portions of the 259e operating program, full of unpredictable noise and frequent silences. This is the innovative Mem Skew mode, possibly the most unique feature of the Buchla 259e. When these tables are selected, the FM controls are re-assigned to table scanning functions and the FM inputs become table modulators.”
