Prefer to pick rather than type? Blocks lets you build and refine a sound across up to nine musical categories: era, sound model, archetype, structure, tone, shape, motion, space and finish—each one a musical choice, not a parameter.
Six synth engines · 20+ classic voices
Six complementary engines give you a portfolio of sound-making approaches: Vintage Analogue, four-operator FM, wavetable, TruTone six-operator FM, hybrid sample synthesis and SuperSynth. Move from familiar vintage colours to modern textures, with over 400 presets in Presets and Examples.
Explore the classics
21 analogue-inspired architectures, each with its own oscillator structure, filter behaviour and modulation routing. They capture distinctive musical character without attempting a complete circuit-by-circuit recreation of the original instruments.
Classic four-operator FM character with eight routing algorithms. Explore woody basses, bell-like electric keys, metallic percussion and expressive digital tones.
Glassy pads, hollow bells and shifting spectral frames. Sweep through digital wavetables via dedicated envelopes and LFOs, then shape with analogue-style filtering.
Inside Vintage Analogue
Classic synthesisers have an individuality worth keeping: how a pad blooms, how brass speaks, how a bass punches and how a lead cuts through. sonarch models over 20 native analogue signal paths, capturing the spirit of vintage synthesis, so asking for a punchy sub bass, a chorus polysynth pad or a screaming dual-filter lead calls up an architecture built for that role. Available controls and routing follow the selected model’s design; the models are not interchangeable collections of every synth feature.
Dual-oscillator eight-voice architectures for lush pads and brass—capable of splitting or layering into two four-voice parts—plus switchable-filter eight-voice polys and stacked-saw voices with a dedicated motion lane for wide, moving leads.
Six-voice oscillator-plus-sub synths with panel or LFO pulse-width modulation and rich chorus; polished dual-oscillator six-voice chorus polys; six-voice low-pass plus high-pass delay polys; five-voice cross-modulated polys; and ensemble string/pad machines.
Eight-voice dual-channel polysynths built around expressive keyboard pressure for swelling brass and long pads, alongside two-oscillator duophonic voices into a four-pole filter for biting leads and bass.
Three-oscillator ladder-filter monos for thick bass and singing leads; single-oscillator + sub monos with bender and glide; resonant acid bass with slide and accent; sharp high-pass-into-low-pass dual-oscillator monos; wheel-modulated dual-oscillator leads; and three-oscillator semi-modular voices with ring modulation and spring reverb.
Take it somewhere new
Explore expressive keys and metallic textures with six operators and 32 classic routing algorithms. Edit the operators and envelopes, or browse and import voices from compatible 32-voice SysEx (.syx) banks.
Bring sampled character into a synthesis workflow, with four-source blending, waveshaping and moving vector textures. Choose a hybrid sample voice from the Presets and Examples catalogue or request it in Text.
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.
The sonarch approach
Our ambition is to keep you making music: quick access to a broad palette of sounds, with the depth to make them your own.
The models focus on recognisable oscillator structures, filter behaviour, envelopes and modulation. Complete hardware emulation is not the goal. If you need every original control, patch point and sonic quirk of a particular classic synth, a dedicated recreation may be a better fit.
Rather than asking you to start from a different front panel for every sound, sonarch interprets your words and configures a playable signal path within its six synthesis engines. This software-first approach brings many musical identities into one workflow, with repeatable results and controls suited to the patch.
Play the first result or dig into sources, filters, envelopes, effects and modulation. Classic models retain their particular capabilities and limits; SuperSynth offers a broader palette for combining synthesis approaches and creating sounds of your own.
Built for real-time playing on your computer. Sound generation runs locally, with no cloud round trip. Playing latency depends on your audio interface, buffer size, host and system load.
Build a sound in stages
These clips compare fresh generations from each complete description. In the instrument, use Apply changes after a manual edit to apply an appended change while keeping your sound and edits.
Choose your starting sound
FM electric piano, dry
A bell-like electric piano, played through three chords. Start dry to hear its attack and decay clearly.
Real sonarch engine renders. Choose a sound and a stage, then press play.
Four deliberate readings
Same words. Four interpretations from the real engine, each a deliberate reading of your description.
Each variation remembers its own PLAY knob positions while you compare. When you use Apply changes to add a change, the four cards become Gentle · Clear · Strong · Bold so you can pick the exact strength of your edit.
Movement, texture & space
A pulse that drives the track. A texture that changes beneath a chord. A reverb tail that carries the moment.
Turn a steady tone into a rhythmic pulse, a slow filter sweep or a wavering lead. Use modulation to bring movement to a held note and expression to a performance.
Shape your own modulation curves for an unexpected rise, a gentle fall or a repeating gesture. Explore wavetable textures that unfold as you play.
Add chorus, echoes and reverb to place a sound in your track. Shimmer brings a luminous trail to spacious pads and cinematic textures.
Advanced · the full instrument
For synth enthusiasts, the first result is just the beginning. Explore the sources, sculpt the filter, shape the envelopes and build movement into the sound. Each model brings its own character and controls, from classic analogue voices to FM, wavetable and Super.
Pattern Lab · MIDI drag-and-drop · Key zones
Turn a held chord into a moving pattern, from a steady synthpop pulse to a restless bass sequence. Explore the rhythm while you play, then drag the MIDI into your DAW to build the arrangement.
Layer two sounds for a richer part, or split the keyboard for bass in one hand and a lead or pad in the other. Keep the performance flowing as the idea develops.
Keep the recipe
Open Sound details 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.

Then a few more words: add vibrato to the mod wheel.
The interactive user guide
Explore interactive walkthroughs and practical examples, from your first sound to deeper sound design. Try musical examples and discover new ways to shape your sound, at your own pace.
System requirements
sonarch runs standalone or as a VST3 / AU plug-in.
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
No. Start with words you’d use with another musician: warm, bright, soft, punchy, or feeling words like nostalgic and euphoric. sonarch programs the instrument and puts useful controls within reach—and if you already know synthesis, you can also type exact values like 230hz cutoff 10% resonance or modulation routes directly in your prompt.
The interactive user guide is built into the instrument, with walkthroughs, practical examples and prompts you can send straight to sonarch. Open it from Settings or Examples inside the app. See the built-in guide overview.
No. sonarch aims to give you quick, repeatable access to the spirit of classic and vintage sounds alongside modern synthesis. Its models use distinct architectures and musical behaviours, but do not reproduce each original instrument in its entirety. Expect familiar character and room to shape it, rather than identical patches, every original feature or a guaranteed match to a hardware reference.
Once the patch is ready, you play a real-time synth running on your computer. There is no cloud service generating each note. Generation speed and playing latency are different: key-to-sound latency depends on your audio interface, buffer settings, host and computer load. sonarch does not promise zero latency on every setup.
No. sonarch is a synth-engine patch-generation system. It interprets your description, selects an appropriate engine—including over 20 classic analogue voice topologies, FM, wavetable, hybrid sample and SuperSynth—and dynamically builds a playable patch, configuring the sound sources, signal path, modulation and effects to shape the tone you asked for. And when you want curated starting points, Presets and Examples also include over 400 presets right beside the prompt.
Sound generation and playback run 100% locally on your computer. Your descriptions aren’t sent to a server, no part of sound generation happens in the cloud, and no AI API key is used. A purchased licence activates once online from Settings → Registration with your purchase email and code, and covers up to 3 computers (with online Release this computer if you move machines). After activation, sonarch runs completely offline.
Yes. Play with a MIDI keyboard (including MPE and polyphonic aftertouch), your computer keys or the built-in preview. Compare variations A–D, shape the sound with macros and detailed controls, or tap a suggestion chip. Append a change to the prompt and choose Apply changes; Request results explains anything limited or not applied. Choose New variations for a fresh set of sounds, and save the result you like.
No. A one-off purchase gives you a perpetual licence to sonarch on up to 3 computers. No recurring subscription payments—keep your focus on making music.
Yes. Generation is deterministic on the same version of sonarch, so the same prompt produces repeatable results. Save a .sonarch patch file to keep your chosen sound and knob edits, or simply save your DAW project—the full patch, prompt, edits and MIDI mappings recall automatically with your session.
Yes. Describe a two-part patch—such as warm bass with soft pad or using ; Part 2:—to load two independent synth parts. Balance them with the P1/P2 Mix knob, mute or edit each part independently, and drag the P1 and P2 bars above the 88-key keyboard to create keyboard splits or layered key zones.
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.
