Cherry Audio Elka-X synthesizer is based on the legendary Synthex , a rare Italian analog synthesizer designed by Mario Maggi and produced by ELKA in the early eighties. Elka-X replicates the original synth’s extraordinary character without sacrificing sound or functionality, thoughtfully expanding the feature set and delivering an authentic Synthex experience at a price that anyone can afford.
The Synthex included a combination of unusual and forward-thinking features that set it apart from other contemporary synthesizers, including highly stable digitally controlled analog oscillators and a flexible four-pole multi-mode filter. Unlike most other popular synthesizers that use CEM3320 filter chips in a low-pass-only configuration, the Synthex filter has a 24dB/octave low pass mode, 6 and 12dB/octave bandwidth modes, and a 12dB/octave high pass mode. Along with the powerful built-in analog chorus effect, this gave the Synthex a distinct and powerful tonality. It was multi-timbral, with the ability to play two separate patches at the same time in split or overdub mode. It even included an innovative four-track sequencer with real-time recording and transposition.
Because ELKA’s main market was home organs, they never really established themselves in the professional synthesizer market. Unfortunately, the whirlwind of excitement caused by the release of the Yamaha DX digital synthesizers in 1983 pushed this excellent instrument into the background, without achieving the deserved success.
By the mid-80s, ELKA made the last Synthex for Stevie Wonder, who used it for a distinctive bass tone on his single “Skeletons” from the 1987 album Characters. Other notable Synthex users included Geoff Downes of supergroup Asia, Keith Emerson, Nick Rhodes of Duran Duran, Peter Howell of the BBC Radiophonic Workshop, and Jean-Michel Jarre who used it extensively on Rendezvous and for his famous “laser harp”. ” sound.
