Lost Synapse - Laura (Synth Plugin) $69

Laura by Lost Synapse is a Virtual Instrument and a Virtual Effect Audio Plugin for macOS and Windows. It functions as an Audio Units Plugin and a VST 3 Plugin.

Laura runs four oscillator engines under a single signal path: a full wavetable engine with a built-in editor (formula box, brushes, per-frame operators, up to 256 frames), classic analog-style oscillators (saw, square, triangle, sine, pulse), two-operator FM, and a set of fractal kernels (Mandelbrot, Julia, Burning Ship, Tricorn, Multibrot, Newton). The fractal kernels are the headline. Their complex-plane coordinate is exposed as a parameter, so modulating it navigates a parameterized space of harmonic content rather than scrubbing between pre-baked frames. Park on a coordinate, attach an LFO to it, and you get slow timbral drift that is hard to reproduce by other means.

Around the oscillators sits a modulation matrix with six envelopes, four LFOs with editable shapes, and a macro layer that combines sources before they reach a destination. Every modulator slot can flip into a multi-segment user-drawn curve via the built-in MSEG editor, with per-segment tension, loop and sustain markers at any float position, tempo-synced rates from 1/32 to four bars, and a gallery of shape templates.

Filter+ is the signature filter section. It hosts Synapse, a 4-pole signature low-pass with always-on warmth, drive-mode-shaped resonance, and a built-in Sing wave-folder that turns the resonance peak into a harmonic, almost vocal bloom. It also offers the usual SVF-based types, ten pre-filter drive characters (Tube, Tape, Diode, Fold, Soft, Hard, Aurora, Mirage, Halo, Tanh), a series high-pass, a live response curve, and conditional dimming on controls that have no effect at the current settings.
The 16-slot FX rack covers chorus, delay, distortion, phaser, flanger, reverb (algorithmic and convolution with user IRs), EQ, granular cloud, spectral freeze, frequency shifter, a resonance network, and a multi-band splitter for routing individual bands through downstream effects. DICE buttons across the synth roll genuinely fresh sounds when inspiration is late.

Licensing is offline, with no telemetry and no cloud server.
A 30-minute-per-session demo runs on any machine without an account.

No audio demos or videos..
Instant skip for me, even though it looks interesting

 

no audio or video demo is definitely weird but hey, at least it has a trial

 

How odd. I can't think of any good reason to keep prospective buyers from actually hearing how a synth sounds and to see it in action on a website that's trying to sell it. What's the upside?

 

Possible reasons include: The manufacturer has just finished programming "Laura's" and wants to start generating revenue immediately, planning to provide videos and sound samples at a later date. It is likely a one-man operation—making it more of a time-constraint issue. The DLL file is dated May 13, 2026.

 

Two skins for Laura are attached! I installed and tested the demo—it's a synth with potential.
