Pocket Operator by Teenage Engineering: Complete Guide
Pick one up and you'll understand the appeal quickly. A Pocket Operator is a tiny synth + sampler powerhouse. It´s about the size of a calculator, runs on two AAA batteries and is controlled entirely by a grid of buttons and knobs. There are no menus to dig through, and nothing to install. You turn it on, and you're already making music. The simple yet intuitive design makes for endless jam sessions.
The origin of the Pocket Operator
Back in 2013, Teenage Engineering's Jesper Kouthoofd asked Swedish denim label Cheap Monday to make custom coats for his team. Cheap Monday said yes, but on one condition: they wanted to build something together in return. Alas, the Pocket Operator was born.
Working with sound designer Magnus Lidström, the team built a stripped-down synth with its circuit board left bare, a basic LCD screen, and a speaker crammed inside. Two hundred prototypes went out at Moogfest in 2014 to test the product, and people went nuts over them. Suffice to say, the project went into production immediately.
At first, Rhythm, Sub, and Factory, launched together at NAMM in January 2015 as the "PO-10 series." Teenage Engineering had aimed for $49 a unit, which eventually ended up on $59 each. Even so, it was still pocket change next to the company's OP-1 synth, which sold for nearly $1,400 at the time. Three units, three sounds (drums, bass, and lead) for less than most single synths cost on their own.
New Pocket Operators were introduced after that:
2017: PO-20 Arcade, PO-24 Office, PO-28 Robot (the arcade series)
2019: PO-32 Tonic, PO-33 K.O.!, PO-35 Speak (the metal series)
What Every Pocket Operator Has in Common
Whichever model you land on, you're getting the same core setup.
Every model builds its sound from scratch using FM, subtractive, wavetable, or physical modeling engines, not pre-recorded loops. There are 16 programmable patterns with parameter locks, which let you automate pitch, filter sweeps, and effects on a per-step basis, so a pattern can evolve instead of just repeating itself.
Effects come built in too: 16 effects come built in too, covering delay, bit crusher, filtering, and more, all triggered live by holding a button.
Two AAA batteries power the units. There's also a speaker built in, so you can hear what you're making without plugging in headphones or an amp. Some models features a built-in mic.
A basic 3.5mm cable chains any Pocket Operator to any other and runs them off the same clock. This makes for an incredible one-person setup. Whichever model you land on, you're getting the same core interface.

PO-12 Rhythm is mainly a drum machine. It packs 16 sounds, each one synthesized rather than sampled. Two of them are melodic enough to sequence into a scale. At $59, it's still the model most people start with, and it holds its own as a standalone drum machine years later.
PO-14 Sub offers 15 sub-bass tones across two octaves plus a second, smaller drum machine inside the same unit. Pair it with a PO-12 and you've got a full rhythm setup.
PO-16 Factory offers melodies. It´s loaded with FM, subtractive, wavetable, and physical-modeling synthesis. Learn the punch-in arpeggio and chord modes early. They're the fastest way to turn one held note into a full moving line.
The Arcade Series
PO-20 Arcade offers Chiptune and 8-bit game sounds, which runs on the same sequencing tools as the other Pocket Operators. This one's mainly for people chasing a specific retro sound.
PO-24 Office pulls its samples from vintage office machines: printers, modem handshakes, etc. It sounds like a strange idea for percussion until you actually hear it in action.
PO-28 Robot, another 8-bit lead synth with glide for sliding notes, 128-step pattern chaining, and the same parameter-lock system as the rest of the Operators. Perfect for Live players.
The Metal Series
PO-32 is perfect if you already know you want deep, tunable kicks and snares. It´s a step beyond the more basic drum engine in the PO-12.
PO-33 K.O.! is the one people outside the synth world have actually heard of, and for good reason. It's a 40-second sampler with a built-in mic, so you can record a record scratch, your own voice, or a spoon hitting a mug, then start slicing it into a beat within minutes. It was popular enough that Teenage Engineering later built the larger EP-133 K.O. II sampler around the same idea.
PO-35 Speak is built specifically for vocals and voice sounds. Eight different voice-processing engines run on whatever you feed it through the built-in mic, landing anywhere from a clean vocoder to something that barely sounds human.
The Limited-Run Collaborations
Two limited collaborations followed later. The PO-133 Street Fighter and the PO-137 Rick and Morty editions runs on PO-33 K.O.! hardware, dressed up with different sound content and casework. Neither is sold new anymore, and both fetch a premium on the resale market.

Prices move around depending on the retailer and region, so Teenage Engineering's own store is the most reliable place to check what things actually cost right now.
A Few Accessories Worth Knowing About
The Operators are fully usable straight out of the box, but a colorful CA-X silicone case fixes the exposed, slightly-too-slippery feel of the board. You can also opt for aftermarket cases, which do the same job.
Teenage Engineering offers MC-3 sync cables. These come in a three-pack, which starts to matter the moment you want to pair up several units. Most sync cables will do, however.
Lastly, keep a stash of AAA batteries around, especially if you're running a synced setup on the regular.
Picking a Starting Point
Never touched a synth before? Start with the PO-12 Rhythm. It's cheap, forgiving, and there's a mountain of content online if you get stuck. If sampling interests you more than programmable sounds, skip straight to the PO-33 K.O.!. Anyone chasing melody and live performance should look at the PO-16 Factory or PO-28 Robot . And for working with your own voice rather than drums or leads, nothing else in the lineup touches what the PO-35 Speak does.
There's no single right answer here. It really depends on what you're trying to make. Whichever one you start with, the sync cable means it probably won't be the last.
