Analog Four MKII

Introduced in 2018 as an evolution of Elektron's beloved analog poly synth, the Analog Four MkII stands out for its fully analog signal path paired with a sequencer that's become a secret weapon for electronic producers worldwide.

Each of its four voices packs two analog VCOs with variable waveshaping across all waveforms, AM/sync modes, dual sub-oscillators, and a noise generator, feeding into a classic 4-pole ladder lowpass filter plus a 2-pole multimode one with overdrive and feedback. Modulation is deep with two assignable LFOs, a vibrato LFO, two waveshape LFOs, plus two assignable envelopes, a dedicated amp envelope, vibrato/autobend envelopes, and LFO fade options. The step sequencer shines with up to 64 steps per pattern across four synth tracks, one FX track, and one CV/Gate track, featuring parameter locks, trig conditions like probability, arpeggiators, micro-timing, and real-time recording. Hardware-wise, it's a compact desktop unit at 385 x 225 x 82 mm and 2.4 kg, with a crisp 128x64 OLED screen, durable buttons, eight performance macros via a quick knob, Overbridge USB integration, balanced main outs, individual stereo voice outputs, two audio ins, four CV/Gate outs (-10 to +10V), two CV/expression ins, and MIDI I/O with DIN sync.

Sequencer enthusiasts love how parameter locks let you evolve patterns on the fly, creating endlessly mutating sequences that feel alive in live sets or studio jams. That said, some find the menu diving a bit deep for quick tweaks, though the performance controls make up for it once you're in the flow.
