JenDie brings rare Jen SX-1000 monosynth to macOS, Windows and iOS
A rare Italian mono that once sold for about £210 now lives on as JenDie, a macOS, Windows and iOS emulation of the SX-1000.

34Audiovisuals released JenDie on June 29, bringing a Jen SX-1000 emulation to macOS, Windows and iOS, with AUv3 support on Apple mobile devices. For a synth that spent most of its life as an obscure European budget mono, that is a striking jump from mail-order catalog curiosity to pocket-sized software instrument.
The original SX-1000 first appeared in 1977 or 1978, depending on the reference, and was sold in Europe as an affordable starter synth. One price history puts the launch figure at around £210, which explains why so many early buyers came to it as a first keyboard rather than a collector’s piece. Today, used hardware listings sit around $727 to $729, a reminder that the cheap Italian mono has long since crossed into rare-grail territory.

What gives the SX-1000 its cult status is not a huge feature count but the particular mix it packed into a small, performance-friendly panel. Vintage Synth Explorer documents a single oscillator, a 12 dB per octave filter, white and pink noise generators, glide, vibrato and an ADSR envelope. Gordon Reid’s analysis goes further, describing the SX-1000 as a hybrid design and unusually advanced for 1978, which helps explain why the instrument still feels like a sideways branch in the analog family tree rather than a generic clone of bigger-name American monos.
That oddness has kept the SX-1000 in circulation through later scenes and artists. Vintage Synth Explorer credits it to Future Sound of London, LFO, Broadcast, Ladytron, The Prodigy, Herb Legowicz, Tim Simenon and others, while other references link it to Caribou, Madlib, Plaid, Shigeto and Witch. Deep Signal Studios has even called it an Italian Minimoog, a nickname that fits the machine’s status as a compact, characterful mono from Jen Electronics in Italy.

JenDie also fits a broader pattern for Diego Capoccitti and 34Audiovisuals, which has been pushing more of its instruments toward iOS with releases like DroneDie and SwarmaDie 2. That matters because the SX-1000 has become the kind of synth most players will never buy, only chase through software. The hardware started as a budget catalog synth, but with the original now a collector’s item, JenDie is the realistic way the Italian mono’s strange little voice gets heard again.
