The Elektron Analog Four MKI is a four-voice analog synthesizer with a built-in step sequencer, CV/gate outputs, and Elektron's signature parameter-lock workflow. It features a fully analog signal path with two oscillators per voice, sub-oscillator, noise generator, dual analog filters with overdrive, and flexible analog routing. The MKI includes an OLED display, backlit buttons, high-resolution encoders, and a rugged metal chassis suited for studio or stage use. Overbridge support was later added via firmware, enabling DAW integration, audio streaming, and total recall functionality.
Sale includes the synth, original power supply, and a new 6-ft USB cable. Please let us know if you intend to use this unit with Overbridge.
