Teenage Engineering OP-1 Field is now with vocoder! The vo(ice)(en)coder revolutionized music since its introduction to the world by Homer Hudley at Bell Labs in 1938.

Designed to analyze and synthesize the human voice, it has been used by iconic artists to make their synthesizers sing. From Wendy Carlos and Bob Moog, to Kraftwerk, Herbie Hancock, Beastie Boys, Tupac, Daft Punk, and countless others.

Now all the OP-1 Field owners can enjoy it.

How to install

The feature can be enabled by downloading and installing the new free firmware update for OP–1 field. Just follow these simple steps:

  • download and install the firmware
  • press synth
  • hold shift and press any sound slot key 1–8
  • load vocoder


With the vocoder active, press mic to select the input source.

This is the input for the voice and it will be used as the modulator.

Any input source, such as the built-in microphone, a headset or even the radio or usb can be used.

After you have selected your input source, speak and play notes on the musical keyboard.

You should now hear your OP–1 field burst into beautiful singing.

n the OP–1 field vocoder, the audio input is passed through a bank of 20 filters with controllable bandwidth and formant shift.

The carrier signal is built-in: a custom 7-oscillator polyphonic synth that goes from a single sawtooth to pure white noise.

As always, everything is fully real-time and can be modulated. The controls at your hand are as follows:

  • blue is a one knob synth engine
  • ochre is formant shift
  • gray is number of bands
  • orange controls the dry/wet mix

Sono un ingegnere elettronico con la passione per la musica ed il suono. Mi sono avvicinato alla musica da autodidatta (salvo una breve parentesi alla University of the Blues di Dallas) e ho suonato nei peggiori locali italiani (con casuali puntate all'estero).
Ho costruito la mia prima radio FM appena finita la terza media. Ho continuato con amplificatori a valvole e transistor fino ad arrivare alla produzione di circuiti integrati.
Collaboro da anni con varie riviste (cartacee e web) di musica nelle quali mi occupo di recensioni di strumenti musicali e sistemi per l'elaborazione del suono. Trovate le mie pubblicazioni su Accordo (, la rivista Chitarre (dal 2010 al 2015) e su Audio Central Magazine (
Produco musica da un po' nello NTFC Studio che serve sostanzialmente per le produzioni di NTFC Band.
