SER-2020 V2

DesktopAnalogMonophonic

Inspired by the rare Synton Syrinx from the 1980s, this semi-modular analog synth brings back that elusive nasal, vocal-like tone with a modern twist—think formant effects that make your patches talk without needing a full vocoder setup.

At its core, two CEM3340-based VCOs deliver thick, stable oscillations with multi-mode sync, detune options, a sub-oscillator, ring modulator, and noise generator, all mixable before hitting the standout filter bank: a creamy 24dB/octave low-pass (CEM3350-based) paired with two independent resonant peak filters for formant programming and everything from bass growls to articulated sweeps. Dual ADSR envelopes—one for VCA, one for filter—pair with two versatile LFOs (reset, shaper, and one-shot modes on LFO2) for deep modulation, while sample & hold, auto-glide, and a patch bay with individual VCO/noise/sub outs invite Eurorack integration or wild rerouting. The Touch 'N Bend pad shines for expressive play, mapping pressure-sensitive MPE gestures like strike, press, glide, slide, and lift to VCO, VCF, or VCA, all in a compact desktop chassis with MIDI/USB DIN thru, CV/Gate, mono audio out, and headphone jack.

Since its 2022 debut, players praise its organic vintage vibe—hollow pulses evoking Roland SH-101, tamed Korg MS nasal bite, and boutique build quality at a sharp price—though some note the mono focus keeps it firmly in lead/bass/experimental territory rather than poly territory. It's a gem for hands-on tweaking that feels alive under your fingers.
