High-end spectral filtering and processing 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 our Modular system. 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. Rare and exclusive The 296e is one of the most expensive and exclusive hardware synth modules in the world, and for very good reason. Its complexity, versatility, and sheer quality make it legendary. Sculpt any sound with this ultimately programmable 16-band graphic EQ. Morph between two separate modulatable response curves. Control the individual levels of each band through external incoming CV or use the internal spectral transfer (vocoding) to link the envelopes of odd and even bands with their VCAs (and vice versa). And use the “freeze” function (as a toggle-button, or externally controlled by CV) to sample and hold these values (envelope times, A levels, or B levels). The 296e Spectral Processor is capable of a startling variety of effects, wonderful world-building from mere white noise, or the separation of musical inputs into any elemental collection of individual parts, to be reused and reimagined at will. Ear-pleasing vocoder The center frequency of each band is pre-selected to complement the human ear’s discrimination curve, with the result that each one sounds meaningfully unique and pleasing. Its capability for intricate transformations allow it to be a real time performance filter, a programmable compound equalizer, and even a spectrum transferring vocoder. 16 band-pass filters are available, each with its own VCA on input, and envelope follower on output. They can be divided into two collections of eight, odd and even. In hardware this function can be used to split the module for use as a limited vocoder, with eight bands performing analysis and eight performing resynthesis. But of course in software you can affordably run a pair of 296e modules side-by-side, for a full 16-band spectral transfer vocoding experience. The user can adjust envelope decay times, and pre-emphasis may be applied to smooth the frequency response for even more malleable vocoding. Special MIDI function A special addition in our software version of the module is the ability to ‘play’ the individual filter bands using MIDI. Note values attach to the different fixed filter frequencies, while MIDI velocity data affects the amplitude value of a given band’s VCA. Add to this the wealth of great-sounding combination options available at a single click in Softube Modular, and the Buchla 296e turns an already attractive ecosystem into a truly expansive spectrum.
