Anthem is a modern, cross-platform digital audio workstation designed for creating and editing music and other audio content. It is desktop-first and works on Windows, macOS and Linux, with a browser-native WASM build coming soon.
Anthem is under active development and currently lacks key functionality and usability features, so it is not yet suitable for use.
Prior to 2024, development was UI-only, focused on proving out Flutter as a viable UI solution.
Development in 2024 and the first half of 2025 focused on building out Anthem's audio engine. This primarily included building a sequencer and live audio graph, as well as a scalable solution for IPC and state synchronization between the Flutter UI and the C++ engine.
Anthem's development is currently focused on building a powerful, usable and productive sequencer. Anthem currently supports MIDI sequencing only, but this is enough to allow us to iterate on the high-level arrangement workflow. Along these lines, we are introducing a novel arranger design that hopes to combine the best of modern pattern-based and linear workflows.
In addition to this, Anthem's architecture already supports compilation to WASM with minimal modification, so we will push for that soon to allow us to build out future features with web support in mind.
After finishing the above, focus will shift to building out Anthem's other features, including:
- Audio-rate parameter automation
- Audio recording and sequencing
- Support for instrument racks and effects chains
- A mixer
- Limited support for audio feedback loops in the node graph
- Plugin delay compensation
- Basic configuration support, including:
- Plugin library with automatic plugin discovery
- Audio environment configuration
This list reflects our current plans but does not represent a commitment of any kind.

There is documentation for developers here, which includes an architectural overview and setup instructions. There is also inline documentation which we intend to improve over time.
