Alesis METAVOX ModFX Vocoder

The Metavox features a built-in oscillator section, complete with several kinds of modulation, that can be controlled by an incoming stereo signal. Alternatively, it can produce a vocoding effect on any external source plugged into the right input, with the controlling (voice) source plugged into the left input.


  • One-oscillator vocoder with four built-in waveforms (saw, rectified saw, square, and noise) in a compact box
  • Can vocode external sources, for polyphonic vocoding of an external synthesizer, guitar, etc.
  • Built-in modulation of the internal oscillator by any of five different mod sources
  • Tempo Sync keeps modulation in time with the music
  • Tap Tempo makes it easy to set the speed of modulation by tapping a beat on the top panel
