Dynacord’s ADD-one reached the period press in autumn 1986. Marcus Ryle, who had just left Oberheim to co-found Fast Forward Design, recalls it as the company’s first client project and says it launched at the 1986 Frankfurt Musikmesse. Contemporary Music Technology and Sound On Sound coverage place the finished eight-channel drum brain in the market that autumn, with expandable sampled-sound memory, eight trigger inputs, MIDI and a route toward the later ADD-drive sampling unit.

When Marcus Ryle left Oberheim in 1985, he, Michel Doidic and Susan Wolf formed Fast Forward Design to keep making new musical tools without having to run a manufacturer. Dynacord was the first client. Ryle remembers the brief plainly: design a new digital drum set. Nine months later, the ADD-one appeared at Frankfurt in 1986. That origin matters. This was not a German firm copying the latest American box; it was a German company commissioning an American design team to build a serious electronic-drum system from the ground up.

Dynacord ADD-one in Music Technology, November 1986
p. 20. “In Brief: Dynacord ADD-one Advanced Digital Drums,” with an exact front-panel product photograph.
A drum brain with room to breathe
Music Technology’s November 1986 preview called the ADD-one an eight-channel drum brain. It began with 1 MB of sample memory, expandable with internal boards, and treated every voice as something that could be routed, filtered, delayed, panned and otherwise pulled away from its starting sample. Eight trigger inputs, MIDI, a backlit display and 128 stored kit setups made it less like a fixed rhythm box than a control room for a player’s own pads and sounds.

The price of a complete drum system
The first reviews did not pretend this was a casual purchase. Sound On Sound expected complete pad systems to reach Britain late in October 1986 at roughly £3,000, while Music Technology printed a $3,995 US price for the drum brain. The difference reflects two reports, markets and configurations rather than one universal ticket. Both describe the same ambition: a professional system intended to replace a pile of separate drum modules, samplers and effects with one programmable centre.

The drummer keeps a hand in the sound
The ADD-one was designed to meet a drummer halfway. Yes drummer Alan White told Music Technology that he had been programming one with Reek Havok and praised the sensitivity of its Dynacord pads, saying they could be set up to feel close to acoustic drums. He did not use sequencers, he said; he wanted to bring in sounds with his fingers. That is the machine’s character in one account: detailed digital storage and processing, but performance still arriving through hands and sticks.
Prince and Jarre: the rack beyond the kit
The ADD-one did not remain only a drummer’s system. Prince’s equipment archive attributes it to the sessions for Lovesexy and Batman, describing kick and snare samples triggered from Linn hardware; the archive should be read as a documented studio attribution, not a claim that every drum on those records came from one unit. Jean-Michel Jarre’s official concert archive also lists the ADD-one in the Hong Kong live rig. Taken together, the two routes show why the box outlived its first sales pitch: it could be a drummer’s responsive voice, or a rack-mounted source folded into a larger production system.
