Start the session fast, with the release caveats still visible.

Choose your platform

Use the current stable redirect for your operating system and keep the platform-specific trust notes visible.

• Windows

  Unsigned installer may show a SmartScreen warning on first run.

  Installer

  • Best path for everyday desktop installs.
  • The button points to the stable redirect endpoint for the current Windows build.

• macOS

  Unsigned DMG

  • Drag OpenStudio to Applications.
  • If macOS blocks launch, right-click OpenStudio and choose Open.
  • If needed, allow it in System Settings > Privacy & Security.

• Linux

  AppImage

  • Self-contained AppImage - no installation required.
  • Make the file executable: chmod +x OpenStudio-*.AppImage, then run it.
  • Tested on Ubuntu 22.04+. Other distros may work with equivalent glibc.

System requirements

• 64-bit Windows 10 or later, macOS 12 Monterey or later, or Ubuntu 22.04+ (other distros with equivalent glibc may work).
• A modern multi-core CPU and at least 8 GB RAM for comfortable multitrack work.
• Audio interface or built-in device with current drivers for low-latency recording.
• Extra storage space for sessions, third-party NAM captures and IRs, and any optional AI tools you install later.

Release and install notes

• Stable download redirects live at /download/windows/latest and /download/macos/latest.
• Stable Linux download redirects at /download/linux/latest - the AppImage runs on Ubuntu 22.04+ without package installation.
• The base app stays lean by keeping optional AI runtime components outside the default installer.
• The NAM Rack engine ships in the base app. Local .nam captures and cabinet IRs need no add-on runtime; connected TONE3000 delivery is optional and requires a TONE3000 account.
• Third-party NAM captures and IRs are distributed separately and remain subject to their creators' licenses.
• Distribution is currently optimized for a zero-cost release path, so unsigned installs may require manual trust steps.
• OpenStudio checks release metadata from openstudio.org.in to discover newer builds.
• That metadata-driven flow helps point users to updates without implying fully signed, one-click background patching on every platform.
• macOS especially should be presented honestly: it is an unsigned DMG release with manual Gatekeeper override guidance.
• Linux AppImage is unsigned - most distros run it without additional trust steps.
• Unsigned builds can trigger SmartScreen on Windows or Gatekeeper on macOS during first launch.
• Optional AI tooling runs through a separate in-app setup that prepares a managed local runtime - no manual Python environment required.
• BS Roformer and ACE-Step setup do not install Stable Audio 3; Stable Audio 3 requires a separate gated snapshot import and runtime setup.
• Once the selected AI setup is complete, model assets can run locally and offline as long as the required files are present.
