The WX series (released in 1993) did implement General MIDI, offered a large blue LCD display, a user-friendly interface and some vintage synth sound presets like Oberheim, ARP 2600, Prophet or Elka Synthex.
Although designed as arranger workstations, WX series had some professional synthesizer capabilities like filter and cutoff (resonance) editing with an integrated powerful 16-track sequencer.
In 2006, the RealPiano Expander was succeeded by the GEM RP-X half-rack module, which featured the DRAKE (DSP RISC Advanced Keyboard Engine) simulating instruments like the Fazioli F308 and Steinway & Sons grand pianos.
[9][10] In December 2014, the Finnish group Soundion Oy Ltd (the new owner of GEM, LEM, and Elka) announced plans for Generalmusic to release a product lineup in 2015, consisting of re-issued models alongside new technology offerings.
By July 2015, there were intentions to launch a reissue of the classic Elka Synthex synthesizer, and a crowdfunding campaign was initiated on Indiegogo.
