Rob Hordijk Design

Rob Hordijk Designs is the brand of 5U modules designed and crafted by Rob Hordijk in The Hague, Netherlands.

The modules
All circuitry is original and follows his own concepts based on over thirty years experience in sound synthesis and electronics design. He has complete control over the whole module building process; R&D, prototyping, panel design, cutting, drilling, PCB etching and populating, final hardware assembly, calibration and testing. All components and every piece of hardware is carefully selected for reliability and comfort in use.

Rob Hordijk
Rob Hordijk has been playing around with synths and computers since sequencing some analog stuff around 1982 with an RCA 1802 based SuperElf processor board. Later switching to an Apple ][+ and the Mountain Hardware Music System, for which he developed a Forth language version that could do all sorts of stuff with the Mountain cards, like KarplusStrong-type plucked string sounds and pitch shifting. His first introduction to a DSP was to the DMX1000 around 1984. In 1986 he switched to Atari ST and an Akai S900. These days he is a Clavia Nord Modular G2 aficionado.
