AnalogFX turns Syrinx-inspired SER-2020 concept into Larynx keyboard synth

AnalogFX made the right move with Larynx: it stopped treating the Syrinx idea like a hard-to-find museum object and turned it into something you can actually play. The new monophonic semi-modular analog performance synth keeps the SER-2020 lineage but adds a 37-key aftertouch keyboard, MPE support and Eurorack compatibility, which instantly makes the concept feel less like a collector’s curiosity and more like a working instrument.

That matters because the original reference point, the Synton Syrinx, was never common to begin with. Created in 1983 by Felix Visser, Marc Paping and Bert Vermeulen, the Dutch mono used a metal touchplate and a formant filter design that made it stand out even among the stranger analogs of its era. Only a few hundred Syrinx units were produced from 1983 through 1984, so any modern machine that channels that architecture has an almost automatic pull for players who chase rare control surfaces and vocal, talking-synth textures.

Larynx looks built to preserve that character instead of sanding it off. It keeps dual CEM3340 oscillators with PWM and sync, plus a sub-oscillator tied to VCO 1, ring modulation and noise. The real draw is the Syrinx-style triple-filter section, with two independent bandpass filters and one lowpass filter built around CEM3350 chips and routed in different ways. That is the kind of layout that can move from nasal and synthetic to full-on formant squawk without feeling like a generic subtractive clone. A formant mode with 16 preset filter settings pushes it even further into synthetic speech territory.

The keyboard version also adds the practical touches that the desktop concept needed. The 37-key aftertouch keybed and Touch’n’Bend pressure controller should make it far easier to shape notes in real time, while the stereo delay can be LFO-modulated and CV-controlled, and the new arpeggiator and sequencer section give it more immediate studio range. AnalogFX’s store listing puts the introductory pre-order price at €929 and the regular price at €1,032.23, with release set for September 1, 2026. Production is limited to just 50 units, which keeps Larynx firmly in boutique territory, but not in the dead-end, impossible-to-find category that has kept the original Syrinx mythologized for decades.

AnalogFX has been working this lane for a while. Its SER-2020 is the company’s best-known formant-synthesis instrument, and the VXC-2220 10-band vocoder shows the same obsession with voiced, articulated analog color. Larynx feels like the first time that approach has been wrapped in a keyboard format that invites performance instead of asking you to admire the panel from a distance.
