The machine in the record

Seed Project / State Seltzer.
Seed Project credits Frank McGinnis with the PO-12 sequencer beat on “State Seltzer”. The pocket calculator-sized machine is doing proper record work here: a concise beat engine folded into a full song without needing to pretend it is anything larger.

The PO-12 rhythm arrived in 2015 with its circuit board left proudly in view. It was the dedicated drum machine in Teenage Engineering’s first Pocket Operator trio, born from the company’s collaboration with the fashion label Cheap Monday. The exposed display, hang tab and tiny controls made a virtue of constraint: this was a beat instrument designed to travel in a pocket, not disappear inside a rack.
Sixteen steps on an exposed board
The factory guide gives the PO-12 sixteen sounds and sixteen-step patterns, entered live with quantisation or placed one step at a time. Parameter locks, effects, swing and per-step retriggers give those small patterns a surprising amount of movement. Sixteen patterns can be chained, so a player can build a longer form without leaving the instrument.
A small system through the audio jacks
The Pocket Operator’s audio connectors also carry its sync pulse. Several units can lock together, with one channel carrying the click and the other carrying sound in combined mode. That decision made the PO-12 part of a little tabletop ensemble: rhythm beside bass and melody, all linked without a MIDI cable or a menu system.Source (1)
What the first reviews heard
Declan McGlynn and Bruce Aisher both singled out the rhythm model from the original trio. They valued its kick, parameter automation, gritty rhythmic character and range of variation, while noting that the symbols, key combinations and sparse feedback asked the user to learn a new compact language. The friction is part of the story: the PO-12 is immediate once its button grammar becomes familiar.
From small setup to released music
The PO-12 has appeared in deliberately restricted recording setups as well as larger productions. Seed Project credits Frank McGinnis with its sequencer beat on “State Seltzer,” while Jason Buckley says all drums on his 2022 album Minimal & Subliminal came from the instrument. Those accounts show an inexpensive board becoming a real production tool — a source of complete rhythms, not merely a novelty beside a laptop.
A PO-12 in *Sandstoned*
Church of Hed lists the PO-12 in the instrumentation for *Sandstoned*. The album used a larger mixed setup, so the Museum does not pretend the Pocket Operator supplies every drum. The credit is enough to show the tiny machine entering a complete record as more than a sketchpad.
