Download .exe InstallerKiwisonic is lightweight and runs on most Windows machines from the last decade.
Windows 10 (64-bit) or Windows 11. Mac and Linux support is planned for a future release.
4 GB minimum. 8 GB recommended, especially if using VST3 plugins or large SFZ sample libraries.
~200 MB for the application. Additional space needed for SFZ sample libraries (varies by library).
Any Windows-compatible audio device. A dedicated audio interface is recommended for lower latency, but not required.
Up and running in under two minutes.
Click the Download button above. The .exe installer file will be saved to your Downloads folder.
Double-click the downloaded .exe file. If Windows SmartScreen shows a warning, click "More info" then "Run anyway" — this is normal for new applications.
Accept the licence agreement and choose your install location. The default location works fine for most users.
Open Kiwisonic from the Start menu or the desktop shortcut. On first launch, pick a genre and start composing.
Free SFZ instrument packs are available through the catalog — pianos, strings, guitars, brass, synths. Browse and install them from within the app.
If you own VST3 instruments, you can load them into any Kiwisonic track. The native VST3 host handles plugin communication with low latency. (VST3 support is coming soon.)
