Helio Workstation is free and open-source music sequencer, designed to be used on all major platforms.

Why another sequencer?

Most of the DAW interfaces often seem overcomplicated, and they only tend to get more and more bloated over time. Many of them are commercial, proprietary-licensed and almost none of them support all major operating systems at the same time.

Helio is an attempt to rethink a music sequencer to create a tool that feels right.

It aims to be a modern music creation software, featuring linear-based/pattern-based sequencer with clean UI, integrated version control for synchronizing project between devices, microtonal temperaments support, small portable builds and more; mainly targeted at hobbyist composers, game developers and indie artists. Check out this YouTube channel for some showcases.

Contributing

Helio is still a work in progress, and there are several ways you could help:

  • Proofread and improve the translation for your native language.

  • Maintain a package for your favorite Linux distro - highly appreciated, please see the list of available and missing packages here.

  • Your thoughts on any usability improvements are welcome: friendly and lightweight UI is the main development priority in this project, so feel free to help identifying the main friction points.
