Everything you need to ship

Visual DSP canvas

Drag blocks, wire connections, see audio flow in real time. Cmajor compiles to WASM right in your browser.

Claude in the loop

Ask for a filter, a limiter, a granular grain. Patchwerk translates your prompt into Cmajor DSP and plugin UI code.

Ship it as a plugin

Export to VST3, AU, CLAP, and standalone. Code-signed and notarized for macOS; EV-signed for Windows.

Every layer, handled.

Patchwerk is a full IDE — not a wrapper or a toy. Here's what's inside.

Cmajor DSP engine

Blocks compile to high-performance WASM via Cmajor — the same compiler used in professional audio toolchains. Zero compromises on latency.

AI that knows audio

Claude is trained with Patchwerk's DSP schema. It understands gains, filter topologies, modulation routing — not just generic code completion.

React plugin UI

Your plugin UI is a live React component. Edit code or ask the AI — changes hot-reload inside the native plugin window instantly.

Version-controlled projects

Every Patchwerk project is a folder of plain files — DSP blocks, UI code, presets. Commit to Git, diff blocks, branch experiments freely.

One-click signed builds

Export produces a code-signed, notarized macOS bundle and an EV-signed Windows installer. Ready for distribution with no extra toolchain.

Factory block library

Oscillators, filters, dynamics, reverbs, delays, and utilities — all peer-reviewed DSP ready to wire. Add community blocks with one command.

From idea to plugin in three steps

No DSP PhD required. No boilerplate. Just build.

01

Design on the canvas

Drop DSP blocks onto a visual node graph and connect them with a click. Oscillators, filters, reverbs, delays — all wired visually without writing a single line.

02

Prompt the AI

Ask Claude to add a sidechain compressor, tweak the EQ curve, or build a full granular synth. It writes Cmajor DSP and your React plugin UI together — in one go.

03

Export & distribute

Hit export. Patchwerk bundles a signed VST3, AU, and CLAP alongside a standalone app — ready to hand to your users the same afternoon.

What beta users are saying

I shipped my first compressor plugin in an afternoon. I've been wanting to do that for three years.

The AI actually understands filter topology. It's not just regurgitating code — it reasons about the DSP.

DSP engineer

Signed builds for both macOS and Windows out of the box. That alone would have saved me weeks.

Frequently asked

Do I need to know DSP or Cmajor?

No. The AI handles DSP generation from plain English descriptions. If you do know DSP, you can also edit the Cmajor blocks directly — Patchwerk gets out of your way.

Which DAWs will my plugin work in?

VST3 works in Ableton, Logic (via wrapper), Cubase, FL Studio, Studio One, Bitwig, Reaper, and more. AU targets Logic and GarageBand natively. CLAP is supported by Bitwig and Reaper.

Do I own the plugin code?

100%. The Cmajor DSP code, React UI, and export artifacts are yours. No runtime license, no royalties, no lock-in.

What happens to my credits when paid tiers launch?

Beta users lock in their free monthly credits for life — even after the paid tier ships. You'll never lose what you signed up with.

Is there a Windows version of the IDE?

macOS ships first. Windows IDE is on the roadmap for 2025. Plugin exports are already cross-platform — your macOS build produces Windows binaries too.

Free forever for beta users
