System Requirements

Kiwisonic is lightweight and runs on most Windows and Linux machines from the last decade.

Operating System

Windows 10 (64-bit) or Windows 11, or a 64-bit Linux desktop with glibc 2.35 or newer (Ubuntu 22.04+, Debian 12+, recent Fedora or Arch). Mac support is planned for a future release.

RAM

4 GB minimum. 8 GB recommended, especially if using VST3 plugins or large SFZ sample libraries.

Disk Space

~200 MB for the application. Additional space needed for SFZ sample libraries (varies by library).

Audio

Any audio device your system supports. On Linux, ALSA, PipeWire or PulseAudio all work. A dedicated audio interface is recommended for lower latency, but not required.

Installation

Up and running in under two minutes.

  1. 1

    Download the installer

    Click the Download button above. The .exe installer file will be saved to your Downloads folder.

  2. 2

    Run the installer

    Double-click the downloaded .exe file. If Windows SmartScreen shows a warning, click "More info" then "Run anyway". This is normal for new applications.

  3. 3

    Follow the setup wizard

    Accept the licence agreement and choose your install location. The default location works fine for most users.

  4. 4

    Launch Kiwisonic

    Open Kiwisonic from the Start menu or the desktop shortcut. On first launch, pick a genre and start composing.

Included sounds and your own plugins

Built-in Instruments and SFZ

A set of instruments is ready the moment you launch, with nothing to install: an Electric Piano modelled on the Rhodes, the TR-808 and TR-909 drum machines built the way the hardware built them, and Kiwisynth, a full wavetable synthesizer with an editable preset library covering bass, leads, pads and keys. Kiwisonic also plays SFZ sample instruments, so you can point it at a free SFZ library and assign instruments to any track.

VST3 and CLAP plugins

Plugin hosting is included, still in early testing. If you own VST3 or CLAP instruments, you can load them on any Kiwisonic track. Kiwisynth installs as VST3 and CLAP and Kiwipulse as CLAP, so they run here and in your DAW, and the sounds you build carry between them.
