Synth1
Synth1 is a free virtual synthesizer VST plugin developed by Daichi. It is a classic subtractive synth designed to run inside DAWs (Digital Audio Workstations) and other host applications that support VST plugins. Synth1 offers basic oscillators, filters, envelope controls and effects, and has been popular among home music producers and hobbyists for its straightforward interface and zero cost. The plugin is loaded and hosted by the DAW or audio application you use to produce music.
AI Recommendation
1 suggestionSynth1 is a VST plugin and cannot be updated independently — it must be managed through your DAW or audio host application. To get a native Apple Silicon version of Synth1, first ensure your host application (such as Ableton Live, Logic Pro, Reaper, Cubase, Studio One, or another DAW) is running the latest native build for Apple Silicon, since most DAWs now include native plugin bridges or run natively themselves. Once your host is current and native, visit Daichi's website or plugin repository to download the latest native VST3 build of Synth1, then use your DAW's plugin manager or preferences to install or rescan the plugin folder. If you cannot locate a native build from Daichi, contact the developer directly to confirm whether a native Apple Silicon version is planned, as Intel-only plugins will stop working entirely when Apple removes Rosetta 2 in macOS 28 (September 2028). As an alternative, consider other free and actively maintained synthesizer plugins with confirmed native builds, such as Surge XT or Vital, which integrate into any VST-compatible DAW.
