Vive la culture libre

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 sequencer with a clean interface, high-performance C++ core, integrated version control providing intelligent synchronization between devices, saved undo history, translations to many languages and more.

Basic build instructions

  • Git clone with submodules: git clone --recurse-submodules https://github.com/helio-fm/helio-workstation.git.
  • Install dependencies:
    • On Windows, get ASIO SDK (which can't be redistributed in this project due to licensing restrictions, but you may use ThirdParty/ASIO/get_asio_sdk.ps1 powershell script to download and extract the SDK source).
    • On Linux, you'll need to have the following packages installed: libfreetype6-dev libx11-dev libxinerama-dev libxrandr-dev libxcursor-dev libxcomposite-dev mesa-common-dev freeglut3-dev libcurl4-openssl-dev libasound2-dev libjack-dev libc++-dev; the makefile assumes you've set up either export CONFIG=Debug, export CONFIG=Release32 or export CONFIG=Release64 before you make.
  • Pick the right project for your OS from Projects directory and build.

Contributing

Helio is still a work in progress with many essential features missing, and there are several ways you could help:

  • Proofread and improve the translation for your native language.

  • Your ideas are welcome: friendly and lightweight UI is the main development priority in this project, and if you have a vision on how to improve user experience in music composing, feel free to share it.

  • Implement new features: some guys were asking me if I have any tasks for them to start working on. But, as a sole unpaid developer with limited amount of time and interest, I'm not planning/decomposing stories or organising the board, instead I only work on the parts that are fun and important for me at the moment. If you feel like contributing and don't know where to start, my suggestion is that you do the same: find a missing feature or behavior you're lacking the most, and make the app a little more convinient for yourself. Anyway, feel free to ask questions and create incomplete PR's to get intermediate feedback.
