Modular Add-On: Buchla 296e Spectral Processor

Softube Buchla 296e Spectral Processor brings an officially licensed Buchla filter bank into Softube Modular. This expansion requires Modular and combines 16-band graphic EQ with spectral analysis and resynthesis for detailed tone shaping, animated filtering, and vocoder-style transformations. Its band frequencies follow the human ear’s discrimination curve, giving each region a distinct musical character. Morph between two modulatable response curves, control individual band levels with incoming CV, or explore internal spectral transfer between odd and even bands. A freeze function holds selected envelope or level values for sustained spectral textures. Use it to turn white noise into evolving soundscapes, pull apart musical material, or create expressive performance patches. It suits modular enthusiasts, electronic producers, and experimental sound designers who want to move beyond conventional EQ into hands-on spectral processing.
