Why we built sonarch
Stay with the idea, not the menus.
Go deep because you want to. Not because you have to.
We’re musicians. We love making music, and we love sound design too. But when a track is taking shape, the most important thing is staying with the idea.
Often, you already know the kind of sound you need. You just want to get to it, without opening another handful of plugins or remembering which oscillator, envelope and delay settings made that sound on that synth.
That’s why we built sonarch. Describe what you hear in your head, try the sounds, then refine, change direction or start again in words. You don’t need to move a control or understand the signal path to keep creating.
And when sound design is the moment? Open up the instrument and explore. The depth is there. The detour is optional.
Describe it. Play it. Make it yours.
You don’t need to know which synth to open or which knob to turn. Start with the sound you want.
01 / DESCRIBE
Use your own words.
Describe the sound in plain musical terms: an instrument, a texture, a feeling. No technical jargon needed. Type your idea or build it visually with Blocks. sonarch chooses the engine and builds the patch.
“a warm, spacious pad”02 / PLAY
Four readings of the same idea.
Explore Literal, Characterful, Modern and Wildcard. Press Hold to keep the sound playing while you compare A–D and turn the PLAY knobs. Or enable Auto-preview to audition each variation as you select it.
Literal · Characterful · Modern · Wildcard03 / REFINE
Keep the sound you like.
After shaping a sound with a knob, keep the original description and append a change. Refine applies the addition while keeping your edits. Use the refinement Undo arrow to compare. Generate starts fresh.
“juno bass” → “juno bass with soft pad”
Hear it in action
Made with sonarch sounds.
Short demo tracks built from described sounds. Every instrument you hear was generated from a single sentence.
Prefer to pick rather than type? Blocks lets you build and refine a sound simply and quickly: era, sound model, archetype, tone, shape, motion, space and finish, each one a musical choice, not a parameter.
Actual product · the chain writes your description as you go · select to enlarge
Every block is a musical word. Choose Punchy, Drifting or Glassy and the description writes itself above the chain.
Keep what you like; explore the rest. Your manual choices lock automatically. Keep the model and archetype locked, then roll the dice to vary unlocked tone, motion and space. Click a padlock to let that choice vary. Each choice or roll generates automatically.
Continue in words. Switch from Blocks to Text to copy your description and edit it. Blocks does not turn an arbitrary typed description back into selections.

Keep the essentials close. Open up the instrument when you want to take an idea further.
Compact view
Everything you need, within reach.
Press Hold, compare A–D, then shape the sound with the PLAY knobs. Hover a knob to see what it does; right-click it for MIDI Learn and assign your controller.

Advanced · the full instrument
When you’re ready, go as deep as you need.
Behind every generated sound is a complete synthesiser. Open the Advanced view and sonarch exposes up to 64 controls across Sources, Tone, Motion, Connect, FX and Perform, plus a five-band parametric EQ, for endless tweaking and refinement. Every one of them can be assigned to your MIDI controller. And because each synthesis model keeps its own architecture, the controls you see always belong to the character of the sound.

FX · click any stage to compare it on and offMotion · shape an LFO, then connect it to something you can hearEQ · five-band parametric, drawn over the live spectrum
Each model, its own controls. Choose a vintage analogue model and you get its oscillators, filter and LFOs. Choose vintage wavetable and you pick from its wavetables. FM gives you operators and algorithms. The Advanced view fits the engine you’re playing, so a sound inspired by a classic polysynth behaves like one.
Six focused tabs, plus EQ. Sources, Tone / Body, Motion, Connect, FX and Perform, each explained in plain language with a Guide one click away. Finish with a five-band parametric EQ drawn over the live spectrum.
Up to 64 controls, all live. Hear ordinary control changes as you play. Some structural edits and Undo/Redo can briefly reload the sound.
Assign anything to MIDI. Map any control to a knob or fader on your controller and perform the sound, not just program it.
Keep the recipe
A how-to sheet for every sound you make.
Click Why in the instrument header to open your sound’s how-to sheet. See its sources, filter, envelopes, movement and effects, and find out which words shaped the result.
See what was read, what was chosen and what wasn’t acted on. Explore the live settings and save the sheet for later. Use the step-by-step guidance as a starting point for recreating the sound on another synth, where its capabilities allow.
Make music first. Learn the sound design when you want to.

saK1 · HYBRID SAMPLE SYNTHESIS
Familiar sounds. Unexpected combinations.
Bring sampled character into a synthesis workflow, with dual-source blending and moving textures. Choose a saK1 sound from the existing catalogue or request saK1 in Text; it is not a Blocks sound-model choice.
sonarch SUPERSYNTH
Analogue energy. Modern ambition.
Explore analogue and wavetable sources, spectral colour and resonant bodies. Shape an evolving pad with drawn modulation curves, then follow Sources, Tone / Body, Motion and Connect to hear how it works.
Not everything. The sound you need next.
sonarch isn’t trying to replace your hardware or an 80 GB sample library. It has a different job: give you quick, repeatable access to the kinds of sounds you’re looking for, with the flexibility to make them your own.
The machine models capture the architecture and calibrated character of their inspirations; they aren’t component-by-component replicas. The aim is the right kind of instrument, programmed for your words.
Arpeggiator & step sequencer
Hold a chord and find a groove.
Let the arpeggiator turn your held notes into a moving pattern. Go up, down or back and forth, and hear a simple chord become the start of a track.
Try a bass with a soft pad layer. Use the part selectors and mute buttons to hear each layer, then adjust their balance. In Pattern Lab, select a part and shape up to 16 steps with notes, lengths and velocities. Return to PLAY and right-click a macro for MIDI Learn to perform the sound with your controller.

From the creator
Why I built sonarch.
I’m a musician myself, and over the years I’ve accumulated a room full of hardware synths, plug-ins and terabytes of sample libraries, only to increasingly find myself overwhelmed by the choice and complexity.
Quite often, I don’t want to spend twenty minutes searching for a sound. I already know roughly what the arrangement needs, and I want to get there while the idea is still fresh.
That’s why I built sonarch, short for Sonic Architecture.
The aim was never to replace the joy of sound design or the studio full of hardware. It was to create a faster route from hearing an idea in your head to having a playable instrument in front of you, without breaking the creative flow.

AAX (Pro Tools) is not currently supported. CPU load depends on the patch, polyphony and sample rate; it is comparable to other modern software synthesisers of similar depth.
A little more about sonarch
Good to know.
Do I need to understand synthesis?
No. Start with words you’d use with another musician: warm, bright, soft, punchy. sonarch programs the instrument and puts useful controls within reach.
sonarch looks sophisticated. How do I learn what it can do?
We’ve tried to keep sonarch intuitive and easy to use for everyone. For those who want to go deeper into the synthesis engine, sonarch exposes a lot of features and depth. To help, we’ve built an interactive user guide into the instrument, with examples and walkthroughs, from your first sound to the six engines, filters, envelopes, modulation and effects. Open it from the settings menu. Each guide prompt can be sent straight to sonarch, so you can read about a technique and hear it in the same moment.
The built-in visual user guide · opens from the settings menuIs this just searching for presets?
No. sonarch is a synth-engine patch-generation system. It interprets your description, selects an appropriate engine and dynamically builds a playable patch, configuring the sound sources, signal path, modulation and effects to shape the tone you asked for. It isn’t just matching your words to a list of finished presets. The sound and its controls stay editable: change its character, refine individual elements or start again, using words or the synth controls.
Do I need an account or an internet connection?
No. sonarch runs entirely on your computer, from understanding your words to building and playing the sound. Your descriptions aren’t sent to a server, and no part of sound generation happens in the cloud. No account, no internet connection and no waiting for a cloud service. Just describe the sound and keep playing.
Can I play and change the sounds?
Yes. Play with a MIDI keyboard or use the built-in preview. Compare variations, shape the sound with controls or refinements, and save the result.
Is it a subscription?
No. A one-off purchase gives you a perpetual licence to sonarch. No recurring subscription payments, keep your focus on making music.
Can I come back to the same sound?
The same prompt produces repeatable results within the same software and rulebook version. Qualification may limit the available variations. Save the patch to keep your chosen sound and edits. The readable patch format also makes it possible to inspect and share what you’ve made.
Can I combine two sounds?
Yes. Build a two-part patch, such as a pad with a pluck, and refine the parts. If a description could mean a layer or a characteristic of one sound, the explanation helps you see how it was interpreted.
Which platforms does sonarch support?
sonarch 1.0 supports macOS and Windows. Use it as a plug-in in compatible music software or as a standalone app. AU and VST3 are available on macOS; VST3 is available on Windows. See the full system requirements.
