Elka EK-22

KeyboardAnalogPolyphonic

When Elka released the EK-22 in 1986, they created something that felt distinctly Italian—a polyphonic synthesizer that blended analog warmth with digital precision at a time when most manufacturers were still figuring out how to marry the two. It's often compared to the Oberheim Matrix 6 in spirit, but the EK-22 carved its own path with a gorgeous built-in chorus and some genuinely flexible oscillator routing options that gave it character beyond the usual subtractive formula.

The EK-22 is built around six voices of analog synthesis powered by Curtis CEM3396 chips, with two digitally controlled oscillators per voice that deliver pulse, sawtooth, and variable waveforms across a 16-foot to 2-foot octave range. The oscillators can sync to each other and modulate via two six-stage envelope generators, an LFO with multiple waveforms, or velocity and aftertouch data from the keyboard. Everything feeds into a resonant 24dB low-pass filter with key follow and emphasis controls, then through dual VCAs for envelope and dynamics shaping. The 61-key keyboard is velocity and pressure sensitive, and you get full MIDI implementation with In, Out, and Thru connectors, plus the ability to split the keyboard into two independent timbral zones with their own tuning and patch settings. The control panel uses a push-button interface with an LCD display for editing, and there's a pitch bend wheel and modulation wheel for real-time performance control.

The EK-22 has aged remarkably well in the hands of musicians and producers who appreciate its particular flavor. The chorus effect is genuinely lush without sounding cheesy, and the combination of stable DCOs with analog filtering gives you that sweet spot between modern reliability and classic analog character. The split function and performance patch memory make it practical for live work, and the free MIDI editor that's available online means you're not locked into menu diving if you want to program deeper. It's the kind of synth that doesn't shout for attention but rewards curiosity—solid, capable, and distinctly its own thing.
