SWARA XT is an open-source monophonic software synthesizer by MontroneDSP, derived in part from the Mutable Instruments Shruthi firmware.
It combines a digital dual-oscillator voice with a resonant four-pole low-pass filter, modulation matrix, envelopes, LFOs, sequencer/arpeggiator, presets, and a scalable themed interface.
- Two digital oscillator sources with multiple oscillator models
- Source mixer, sub oscillator, and noise
- Resonant four-pole low-pass filter
- Two envelopes and two LFOs
- Free-running and host-synchronised modulation
- Sequencer and arpeggiator
- 12-slot modulation matrix
- Factory and user presets
- Multiple interface skins and sizes
- VST3 and Standalone formats
New to SWARA XT? Read the Quick Start Manual.
- Download the current archive from GitHub Releases, or build from source.
- Install the complete VST3 bundle in a VST3-compatible host location and rescan the host, or launch the included Standalone application.
- Select a factory preset from the preset selector, or save a complete user preset with SAVE.
- Send MIDI notes to the instrument track and route that track to an active audio output.
- Open SEQ/ARP to use the internal sequencer or arpeggiator when desired.

Manual archives remain available from GitHub Releases.
The official Linux build is available free from the GitHub Releases page.
The current public Windows x64 package is available from GitHub Releases.
No macOS archive is published with the current 1.2.3 GitHub release; see BUILDING.md to build the current source locally.
SWARA XT is a real-time software synthesizer. CPU usage depends on sample rate, audio buffer size, active modulation, and host configuration.
Very small audio buffers and high sample rates require substantially more processing power. For reliable real-time use, a modern 64-bit processor is recommended.
- 64-bit processor
- 4 GB RAM
- 100 MB free disk space
- VST3-compatible host for plug-in use
Platform-specific compatibility may depend on the operating system, host, and locally installed system libraries.
Building SWARA XT requires CMake 3.22 or newer, a C++17-compatible compiler, JUCE 9.0.1, Git, and the pinned Shruthi source used by the project.
See BUILDING.md for build instructions.
SWARA XT software is distributed under GPL-3.0-or-later.
