Moog SPECTRAVOX Analog SynthesizerSpectravox, the newest member of the Moog semi modular family, is a groundbreaking tool for sculpting sound. An analog spectral processor based around a 10 band filter bank, Spectravox creates lively drones and colorful tonal sweeps on its own and adds resonant depth and psychedelic spectral movement to any external sound. Hook up a microphone and Spectravox becomes a 10 band analog vocoder with innovative integrated modulation of all of its filters.
