Moog | Spectravox Semi-Modular Synthesizer
Sculpt Your Sound with the Moog Spectravox Semi-Modular Analog Spectral Processor!
Meet the latest addition to the Moog semi-modular synth family with the Moog Spectravox analog spectral processor synthesizer, now available at Chicago Synth Exchange! Designed around a 10-band filter bank, the Moog Spectravox lets users create lively drones and colorful tonal sweeps as a standalone synth—or, it can also be used to add resonant depth and psychedelic spectral movement to any external sound! Just hook up a microphone, and the Spectravox becomes a 10-band analog vocoder with innovative integrated filter modulation, expanding the topology of the vocoder and filter bank for extensive sonic exploration.


Since the Moog 907 Fixed Filter Bank appeared in the 1960s, synthesists have delighted in playing with the spectrum of sound, creating lush vowel tones and multicolored timbral animation with hands-on level control of each frequency band of a sound. Inspired by the pioneering vocoding work of Bob Moog and Wendy Carlos in the late 1960s—which was based on Homer Dudley's original designs from the 1930s and later used to prominent effect in Stanley Kubrick's 1972 film A Clockwork Orange—the Spectravox comes with a comprehensive patch bay, making it easy to integrate this highly flexible instrument and signal processor into studio rigs of any size.
Unlike earlier fixed filter banks, the unique filters of the Spectravox are no longer fixed in place, but rather will jointly shift around the frequency space, letting users create otherworldly voltage-controlled spectral animation and vibrant phaser-like sweeps. Equipped with 10 filters, each with a variable resonance that can morph from soft precision to shimmering choral effects, the Spectravox lets users reshape the sounds they love into surprising new forms, bringing a new level of sonic possibilities to any studio.
Plus, with its combo XLR/jack program input, the Spectravox can be used as a fully featured 10-band vocoder with a secondary filter bank for analyzing the spectral makeup of incoming sounds. Using Vocoder mode, its 10 analysis filters map the timbral characteristics of any external sound onto any other sound imaginable. Use the Spectravox to scramble the frequency spectrum and create wonderfully unpredictable textures with patch points for each filter in the filter bank and included patch cables. Or, add analog warmth and subtle phasing to digital synthesizers and sound sources. Or, integrate the Spectravox with other Moog semi-modular instruments or Eurorack modules, using its extensive patch bay that lets users control virtually all its parameters.
