Software reconstruction of the 1998 Yamaha FS1R synthesizer. FSVR, Formant Synthesizer Virtual Rack, is a software reconstruction of the Yamaha FS1R as a plugin and a console synth: its firmware logic rewritten in C++ from the decompiled ROM, four parts, 32 channels, the filter, both LFOs, pan, the three effect blocks, performances and Fseq playback. CLAP, VST3, VST2 and standalone on Windows, macOS and Linux, an AU on macOS and a 32-bit VST2 with a DXi on Windows, with an editor for every parameter the unit has, a bank manager for your own .syx libraries and Import Audio for Fseqs.

All 88 algorithms
Every FM algorithm from the hardware, with the voiced and unvoiced operators the FS1R is known for.

The factory banks built in
1408 voices, 384 performances and 90 formant sequences read out of the ROM, so the patch browser needs no dump of your own.

Fseq playback
The formant sequences that made the FS1R sound like nothing else, with every loop mode, the start delay and MIDI clock sync.

The front panel is the GUI
Down to the cursor stops and the controller set, read out of the firmware’s own screen tables rather than off a photo.

An installer for every format
Windows, macOS and Linux, built on every push. The installer puts VST3, CLAP, VST2, the 32-bit VST2 with its DXi, AU and the standalone in place, and keeps them up to date through musica.studio.

A remake of the old reFX Vanguard 1 VST exclusively from  community. It’s not reverse-engineered, but meticulously measured and recreated, making it technically its own independent instrument while staying as close to the original as possible. The Source Code is provided in the zip File as well for you to inspect or reuse, I claim no ownership whatsoever. You can compile it for Mac and Linux as well.

It loads the original presets, that sound approximately 99% similar to the originals, at least you can’t hear the difference if you want to ignore the minor differences. The GUI features a classic 2000s Frutiger Aero aesthetic, with glossy surfaces, gradients, and that distinctly nostalgic early-digital look.

It also includes preset-class randomizers to generate variations within specific preset categories.

The famous Plugin reamagined.

A playable vowel/formant synthesizer built around a single expressive Vowel/Voice pair, an onboard unison choir engine, and a complete internal FX chain — saturation, chorus, tempo-synced ping-pong delay and a shimmer/cathedral reverb — all driven from one XY pad, with an animated mouth that lip-syncs to what you play.

Features:

Vowel/Voice vocal synthesis engine with glide, vibrato and an aspiration (breath noise) control

Up to 16-voice polyphony, independent of the built-in Unison/Choir engine (1–10 detuned voices stacked per note)

Interactive XY pad for live Vowel/Voice performance, with a preview-note mode so you can hear changes while dragging without holding a MIDI note

Configurable pitch-bend routing: classic vowel-morph mode, combined pitch+vowel, inverted, or plain pitch

Full ADSR amplitude envelope

Built-in FX rack: Saturation/Drive, Chorus, tempo-syncable Ping-Pong Delay (free or note-division synced) and a Shimmer/cathedral-style Reverb, blended with one master FX Mix fader

Animated mouth-movement GUI component that reacts to the current vowel and amplitude in real time

Panic button — hard-resets every voice and the FX chain in one click for stuck-note recovery

Remembers its own UI scale (100%/75%) between sessions

Orbinator is a wavetable synth where the wavetables are not fixed — they evolve.

Place one or more orbs and give them a speed, direction and rotation radius. The line that connects the orbs describes a single cycle of the waveform that gets played. Because the orbs move, the wave is always changing shape.

This plug-in was inspired by an obscure method known as scanned synthesis where the wavetable is dynamically generated from a physical model of masses and springs. In Orbinator, the “physical model” consists of dots spinning around circles with an imaginary string between them.

How to use
Double-click anywhere in the window to add a new orb. You can add up to 8 orbs.

Hover near the center of a circle to reveal additional controls that do the following:

SPEED Click on the icon and drag up or down to change the rotation speed and direction. Double-click to stop the orb from moving.
MOVE Drag to reposition the circle. Double-click to delete this orb.
SIZE Drag up or down to change the circle radius. Double-click to restore default size.
Main controls:

SYNC If enabled, the rotation speed of the orbs is relative to the BPM. Speeds range from one 1/16th note per revolution (fast!) to 16 bars (slow).
UNISON Adds extra detuned voices.
SMOOTH If enabled, uses smooth interpolation between the orb positions, otherwise uses linear interpolation. (The UI always shows straight lines even if smooth is enabled.).
TUNING Pitch adjustment in octaves, semitones, and cents.
ADSR Your typical envelope controls.
BEND Amount of pitch bend in semitones, for the pitch wheel.
VEL Velocity sensitivity. If off, velocity is ignored.
SPD Sets the simulation speed, from 0.1 – 10×. This affects the speed of the orbs. You can also use the mod wheel for this. (Note: The animation speed in the UI doesn’t change.).
OUT Output level in dB.
Supported platforms
Free download for Mac (AU, VST3), Windows (VST3), and Linux (VST3, LV2).

ATLAS: Concatenative Synthesis Plugin
Rebuild Any Sound From Fragments Of Your Own Sample Library
ATLAS listens to incoming audio and recreates it with matching fragments from your own samples.

Your performance supplies the pitch, rhythm, and dynamics. Your library supplies the sound.

Turn drums into voices, melodies into drums, and vocals into rain, glass, and wind, all in real time.

Reimagine Your Sample Library in Unexpected Ways
Load a folder of vocal hits, send a drum loop through ATLAS, and hear those voices take on its rhythm.

Try bells against a melody. Field recordings against a vocal. A collection of textures against a sharp, percussive groove.

ATLAS searches inside your samples for fragments that resemble what you’re playing, then uses them to rebuild the performance.

How Does ATLAS Work Exactly?
Start with the included factory library or load a folder of your own samples.

ATLAS analyzes your incoming audio 40 times per second, finds fragments with the closest spectral match, and plays them back in place of the original sound.

It follows the performance as it happens, so you can experiment while your track plays.

SKETCH: The Instrument Plugin That Turns Drawings Into Melodies
Cymatics SKETCH turns anything you draw into a melody.

Choose your key and scale, pick a colored pen, then draw lines, curves, patterns, or completely random shapes across the page.

Make Melodies Without Overthinking Them
Sometimes the hardest part of producing is getting the first idea down. You open the piano roll, click around for a few minutes, and everything starts sounding too familiar.

SKETCH breaks you out of that pattern by turning melody creation into something visual, immediate, and unpredictable. Instead of thinking about individual notes, you can think in shapes, motion, and direction.

Draw what the melody should feel like and let SKETCH translate it into music.

How Does SKETCH Work Exactly?
Start by choosing the key and musical scale of your project.

Next, select your loop length and quantization to control how your drawing moves with the rhythm.

Pick one of the colored pens and begin drawing. Each pen is connected to a different sound, so changing colors instantly gives your melody a new voice.

Switch on the grid when you want more control, or leave it off when you want to draw freely. You can erase individual sections, undo changes, clear the page, and continue reshaping the idea until it feels right.
