Blippoo Box Legacy arrives in Eurorack, reviving Rob Hordijk’s vision

The Blippoo Box has crossed into Eurorack for the first time, and that matters because this was never a polite synth to begin with. Biyiblip’s Blippoo Box Legacy is being built one by one in Mallorca, and Noisebug is already listing it at $1,999 in both 1/4-inch and banana-jack versions, while calling itself the exclusive North American distributor.

What changes in Eurorack is not the instrument’s temperament but its neighborhood. Rob Hordijk designed the Blippoo Box as a living instrument of interaction, instability, resonance, and discovery, and his own 2009 Leonardo Music Journal article framed it as a chaos-theory device that invites improvisation with unpredictable behavior. In other words, the point was never to tame it. The appeal of the Eurorack format is that the box can now sit beside familiar modules in a standard rack, making Hordijk’s unruly logic easier to patch into an existing system without asking players to build an entirely separate ecosystem around it.

That accessibility comes with a shift in how the machine is encountered. Earlier Blippoo Box units were made in small batches and, in HAINBACH’s 2024 video description, were said to have sold for about 650 EUR. The Legacy version does not erase that cult history, but it does move the design out of scarcity alone and into a format many modular users already live in every day. For players who know the original only by reputation, the new version is less a museum piece than a direct route into Hordijk’s sound world.

The timing also carries emotional weight. Hordijk, born in 1958 in the Netherlands, died on September 6, 2022, at age 64. MusicTech reported that he began learning electronics at 12, later became known for the Hordijk Modular System, the Benjolin, and the Blippoo Box, and saw those designs as the core of his work. On ModWiggler, users reacted warmly to the idea of Biyiblip carrying the legacy forward, with one saying they were “really happy” the project was being continued and evolved. That continuity is the real story here: not a copy, not a replica, not an imitation, but a new chapter for one of modular’s strangest and most original voices.
