Helio app
Helio is Multimedia application that is open source under the GPL-3.0-only license. 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.
