Helio overview

Helio is one music sequencer for all major platforms, desktop and mobile.

  • Distraction-free - Helio is an attempt to rethink a music sequencer to create a tool that feels right. It provides a lightweight UI to help you get into the zone and focus on your ideas.
  • Clear over clever - Visualize music in a way that doesn't seem so smoke and mirrors. The app may serve as a learning tool you need to grow as a composer.
  • Cross-platform tech - Available for all major platforms, desktop and mobile. Hosts VST and AudioUnit, runs on CoreAudio, ASIO, DirectSound, ALSA, JACK and OpenSLES. Exports to MIDI, WAV and FLAC.

Note: While the software is classified as free, it is actually donationware. Please consider making a donation to help support development.
