Teenage Engineering OP-1 Field Portable Synthesizer Workstation

Professional musicians, recording artists, and sound designers in search of a highly portable music making device will be thrilled with the teenage engineering OP-1 Field, the latest flagship instrument that builds upon the success of the original OP-1 with over 100 enhancements, refinements, and upgrades. The aluminum body has been lowered around the keyboard and feels thinner, lighter, and more precise. There's also a 2.4 GHz antenna system that's been fitted inside, and the rear panel now has a plastic cover with two soft Velcro rings for fastening to covers and other accessories.

The OP-1 Field is now stereo throughout its entire signal chain and includes Bluetooth MIDI, USB-C, and an updated speaker system with a passive driver for detailed, fat, and loud sound. The battery has been expanded to 24-hours of continuous use, while the system engine offers multiple tapes and recording formats including Studio 4-Track, Vintage 4-Track, Porta, and Disc Mini. You'll love the new reverb effect and the Dimension synth engine. A flush, all-glass, high-resolution display is easier to read with all new graphics. The unit can also broadcast over FM for even more flexibility.

Firmware Update 1.4.2

  • New vocoder synth engine
  • Start armed tape recording on external MIDI
  • MTP allows AIFF and AIFC files for patches



With the vocoder active, press mic to select the input source. this is the input for the voice, the modulator, and you can use any input source, such as the built-in microphone, a headset or even the radio or usb. after you've selected your input source, speak and play notes on the musical keyboard. you should now hear your OP–1 field burst into beautiful singing.

In the OP–1 field vocoder, the audio input (the modulator/your voice) 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. Everything is fully real-time and modulate-able.

  • Blue: One knob synth engine
