Sequential Circuits Drumtraks

Thirteen tap keys put recorded drums under the fingers. Drumtraks let a player write changes of level and tuning into a pattern, then connect the box to other instruments through MIDI.

Sequential Circuits introduced Drumtraks at the turn of 1984 as a sampled rhythm section for the emerging MIDI studio. Its patterns, songs and tuneable percussion made it a practical partner for a keyboard-led composing setup.

Sequential Circuits Drumtraks — a rhythm section with instructions

The June 1984 advertisement puts a whole recording room behind Drumtraks: tape reels, a drum, then a low black box with wood cheeks, keys and a numerical display. It records Sequential’s ambition for a writable rhythm instrument, not a reconstruction of a studio or a particular record.

The room around the box

Sequential placed Drumtraks beside the Six-Trak and Prophet-T8 as MIDI became a working connection between instruments. Warren Cann tried it with a Prophet-T8, using a velocity-sensitive keyboard to perform dynamic changes more quickly than entering each level on the Drumtraks panel. The machine was a complete object, but also a member of a roomful of objects.

Thirteen tap keys name the recorded voices, while displays and mode lights handle the less visible work. Cann found repeated mode selection interrupted his train of thought, but also found the lit controls made the machine’s state legible. That friction belongs beside the promise.

More than thirteen fixed sounds

Individual levels and tuning could be written into patterns, so repeated hits need not arrive with identical weight or pitch. Chris Everard treated those changes as creative decisions; Sequential advertised the flexibility. These are reviewed and promotional descriptions, not permission to call every resulting timbre a new factory sample.

Six grouped outputs separated families while leaving some combinations tied together. Cann took the machine to Mayfair Studios, liked most of its sounds, was less taken with the toms, and bought one. That is ownership and judgment, not an Ultravox recording credit.

Thirteen taps, six grouped channels.

Bass drum: one of six grouped output channels. No audio is played.

Panel voices: bass drum, snare, rim, two toms, two cymbals, open and closed hi-hat, clap, tambourine, cowbell and cabasa.

The connection was played, too

Juan Atkins remembers making Model 500’s “No UFOs” with a TR-909 and a Sequential Drumtraks linked together in an Ypsilanti apartment studio. His account establishes the pair in that work, but does not assign individual voices, sections, cable routing, timing or stems to either machine.

The silent connection study therefore names an attested pairing, not an emulation of the original setup.

A pattern can leave the machine

Alexis Taylor described making patterns on his Drumtraks, processing and recording them, then moving the result onto a CDJ to alter pitch before bringing it back into his work. The 2014 photograph shows his actual machine in a later studio context. His sticker-inspired “Drum Machines Have Got No Soul” was an unreleased work in progress at that date, not a released-track credit.

The wider archive keeps differently graded associations separate: direct accounts, track credits, release lists, equipment inventories and a sample library should not become one undifferentiated song list.

The machine that stayed writable

Drumtraks arrived as sampled percussion, tune and level changes, cassette memory, MIDI and clock connections, plus a few paths into a mixing desk. The manufacturer ad shows the aspiration; Cann’s review shows its use; Atkins and Taylor show distinct later methods. The thread is not one sound that conquered a genre, but a rhythm that could remain writable.

Alexis Taylor / Hot Chip / “Drum Machines Have Got No Soul” and Taylor’s studio method

Alexis Taylor says he used his Sequential Drumtraks “a hell of a lot,” building patterns before driving them through phaser, chorus and flanger, recording the results and pitching them again through a CDJ. He names an unreleased piece, “Drum Machines Have Got No Soul,” as one result of that method.

A rhythm section for the MIDI studio

Sequential announced Drumtraks in early 1984 as a machine that could work alongside its keyboards, not merely keep time beside them. Its thirteen percussion voices, tune and level controls, cassette storage, patterns and songs gave a musician a complete programmable rhythm part in one wooden-sided unit.

The wider Sequential system

The company’s spring advertising placed Drumtraks with the Six-Trak and Prophet-T8. A keyboard could record dynamic drum performances, and the machine could then carry those ideas into a song. That combination made the pitch of the instrument clear: it was a rhythm machine designed for people already building arrangements with MIDI.

A documented place in Detroit

Juan Atkins has described the Drumtraks as part of the working setup around Model 500’s “No UFO’s”. It is a useful, specific association: one named machine in a documented artist’s process, rather than a vague claim for the entire catalogue of a genre.

Juan Atkins’ early MIDI relationship

Juan Atkins describes the Drumtraks linked to a TR-909 for Model 500’s “No UFOs”. The pair did not behave like a modern, effortless clock: he still had to start and align the Roland by hand. That small operational friction is part of the record’s history—a machine connection performed into place.

A machine Warren Cann bought himself

Warren Cann’s 1984 review ends with the practical vote that matters: he bought the Drumtraks. It is an ownership and testing account, not an Ultravox session credit, but it shows a working drummer encountering a programmable box as a serious instrument rather than a novelty.
