Teenage Engineering OP-1: The Synth That Looks Like a Toy

Teenage Engineering announced the OP-1 at the Frankfurt Musikmesse in 2009, brought a prototype to the NAMM Show in Anaheim the following January and started selling it in 2011. It was the Stockholm company's first product, a thin powder-coated aluminum slab with 24 keys, four knobs and a 320 by 160 pixel OLED screen.

Four Guys From Stockholm

The company was founded in Stockholm in 2005 by Jesper Kouthoofd, David Eriksson, Jens Rudberg and David Möllerstedt. The first three had run a game company called Netbabyworld between 1999 and 2003. Möllerstedt had headed the audio department at the game studio EA DICE. So the team that made a synthesizer came from games and graphics, not from the old synth houses, and the OP-1 shows it.

Most synths of the period looked like lab equipment or furniture. The OP-1 looked like a calculator someone had designed for fun. The black keys look more like buttons than piano keys. The screen draws a cartoonish graphic for each mode instead of a wall of numbers. Plenty of early coverage called it whimsical and toy-like, and that is fair. It is also misleading, because the toy is a serious instrument.

A Synth That Thinks It Is a Tape Deck

Under the playful screen sits a six-voice synthesizer with a list of engines that reads like a band lineup. FM, Cluster, Digital, DNA, Dr Wave, String, Phase, Pulse and Voltage, plus a sampler. You can sample from the built-in microphone, from an audio input, or from the built-in FM radio, which can also modulate effects. A G-force sensor inside lets you tilt the whole unit to control effects.

The real hook, though, is the tape. The OP-1 records onto a four-track digital tape deck that behaves like a cassette portastudio. You can record over what is already there and flip recordings into reverse. Instead of a piano roll or a grid of clips, you get the constraints of tape, and those constraints are why people finish songs on it. The foam packaging even doubled as a carrying case.

The design world noticed. The OP-1 won one of Sweden's Design S Awards in 2012 and took second prize in Georgia Tech's Margaret Guthman Musical Instrument Competition in 2014. The San Francisco Museum of Modern Art added one to its permanent collection, donated by the company. Musicians noticed too. Beck, Depeche Mode, Jean-Michel Jarre, Justin Vernon of Bon Iver, Chvrches and Efrim Menuck of Godspeed You! Black Emperor have all been cited as users, which is a strange and wonderful spread of taste for one small keyboard. The full list lives on the OP-1's Wikipedia entry.

The Year It Disappeared

From late 2018 into early 2019, you couldn't buy a new OP-1. Teenage Engineering had run out of the AMOLED screens it depended on. Rumors spread that the synth was gone for good, and used units started selling for more than the original retail price, the same resale pattern that drives the sneaker resale economy. Production came back in February 2019 with a retail price about 35 percent higher, to cover new parts and redesigned hardware. A lot of fans grumbled about poor planning. They paid anyway.

That moment captures the company's strange position. It makes music gear, but it is treated like a fashion label with drops, sellouts and collectors. The first Pocket Operators, launched in January 2015, were a collaboration with the Swedish denim brand Cheap Monday, and they looked like bare calculator circuit boards. The OD-11 wireless speaker took its shape from a 1974 Sonab speaker by Stig Carlsson, a look backward at Swedish audio history.

After the OP-1

The OP-Z followed in September 2018. The company designed the Frekvens audio and lighting collection for IKEA, worked with Nothing on the ear (1) earbuds of 2021, built the crank for Panic's Playdate handheld and co-designed the Rabbit r1 AI gadget announced in January 2024. Its EP-133 K.O. II sampler arrived in November 2023. In May 2022 came the OP-1 field, the long-awaited successor to the original.

The thread running through all of it is a kind of Scandinavian clarity with a sense of humor, closer to the Danish lineage in our Bang & Olufsen design history than to anything from the big Japanese synth makers. It also sits comfortably next to Dieter Rams and his ten principles, with more jokes. If you plan a design trip around Scandinavia, our Copenhagen design guide is the natural next stop.

In 2012 the company sold accessories that fit onto the OP-1's knobs, including one built to work with Lego gears and motors. Nobody needed that. It is exactly why people fell for it.
