Erebus Desktop Analog Semi-Modular Synthesizer (2022 Reissue)

DesktopAnalogParaphonic

Back from the underworld, this 2022 reissue revives the original Erebus vibe with warmer, more stable oscillators that stay locked in tune, delivering that signature Dreadbox darkness right out of the box.

At its core, two analog VCOs offer saw and square waves with separate glide controls per oscillator and a new hard sync function for ripping leads, feeding into a characterful 2-pole lowpass filter that's always got a touch of residual resonance for thick, aggressive tones. You've got dual envelopes—one full ADSR and a snappier AR for amplitude—plus a wide-range LFO, all tied together with an OTA VCA and lo-fi delay for instant space and grit. The compact desktop design measures 215 x 130 x 65 mm and weighs just 0.9 kg, with 18 patch points (15 in some counts) for CV/Gate, clock sync, and Eurorack integration—it's 42HP ready, USB-powered for portability, and includes MIDI USB in, audio I/O, and headphones out on the front panel.

Synth enthusiasts dig its sturdy build, smooth pots, and bass-heavy paraphonic punch for acid lines, psychedelia, and modular mayhem, though some note the fixed filter resonance colors even clean waves and wish for legato glide.
