Orfeo ~ FOSS Piano Tutor


Orfeo is a free, open-source desktop app that turns MIDI files into an interactive piano lesson: notes fall onto a virtual keyboard in real time, keys light up as they play, and you can slow down, loop, transpose, and explore any passage at your own pace. Real-time chord detection, hand-coloured keys, interactive chord and scale explorers, a full mixer, and per-note editing — with a piano roll that looks like it was built this decade.

Levyra-deepsound ~ FOSS Music Player


Play streamed music and your own files in the same app, save tracks for offline listening, and follow synced lyrics. Levyra does not need an account and does not track you.

Features:

  • Native playback: Media3 and ExoPlayer on Android, libVLC through direct C bindings on Windows (no web wrappers).
  • Gapless & audio tuning: uninterrupted album transitions, crossfade, pitch shifting, custom playback speed, 10-band EQ, and AutoEQ headphone profiles.
  • SponsorBlock: automatically skips sponsored segments, intros, outros, and non-music chatter.
  • Audio & video modes: one-tap switch between audio-only streaming and full video with subtitle tracks.
  • Clean offline downloads: saved directly in device storage as standard M4A files with metadata, artwork, and lyrics.
  • Unified library: local files and streamed tracks share the same playlists, favorites, and queues.
  • Optional YouTube Music sign-in (Android): connect your account to browse your music and import playlists, liked songs and albums. No account needed if you’d rather keep using Levyra as it is.
  • Queue Spaces: keep multiple active listening sessions side by side without losing your current queue.
  • Synced lyrics: tap-to-seek, manual timing adjustments, dedicated Bluetooth latency offset, and non-Latin romanization.
  • Visuals: motion artwork on the Now Playing screen, falling back to animated album covers.
  • Global skins (Android): seven complete looks, each with its own layout and not just a new set of colors. Nocturne 78 brings vintage hi-fi warmth, Prism pairs deep black with raspberry accents, Torque goes for bold graphite shapes and Ivory is a soft, bright look with a dark mode of its own. Spotify Style, Apple Music Style and YouTube Music Style follow the layouts people already know from those apps. Every skin restyles Home, Explore, Library, Settings, the mini player and the full player. You’ll find them under Settings → Design → Skin. Levyra Default stays the default, and your customizations are kept when you switch back and forth.
  • Theme Studio: sixteen presets, including Midnight, Aurora, Pure Material, Velvet and Editorial. You can also build your own themes: pick background, surface and accent colors from swatches or a HEX code, choose light or dark, set how round the corners are, then save, rename or duplicate them. Levyra Aura stays the default, and one tap brings it back.
  • Mini player studio: five alternative mini player designs (Super Expressive, Floating, Liquid Glass, Ultra Compact and Artwork Focus), each with its own size, shape, progress bar and control options, plus a live preview. The original mini player stays the default, so nothing changes until you pick something else.
  • Navigation studio: four extra styles for the bottom bar (Super Expressive, Floating Dock, Minimal and Expressive Compact). Drag the buttons into the order you like, hide Explore or Library, choose when labels show, and pick the indicator, icon size, height and background. Home and Search always stay in the bar.
  • System integration: Android Auto, lockscreen media controls, persistent notifications, and Quick Settings tile.
  • Device integration (Android): Levyra recognizes the phone it runs on and turns on what that system supports. On HyperOS 3 it shows synced lyrics in the Super Island, on OriginOS it shows the current track in the Atomic Island, and OPPO, OnePlus and realme keep their system lyrics panel. Samsung’s Now Bar and other phones use the standard media controls. Settings → Integrations shows what was detected and links to the right battery page for background playback.
  • Song recognition: on-device music identification through the microphone or internal audio, saved in local history.
  • Explore: live radio stations, international charts, and genre or mood browsing.
  • Levyra Vault: backup and restore playlists, favorites, history, and preferences in a single local file.
  • Private stats: on-device play counts and listening hours, with optional Last.fm and ListenBrainz scrobbling.

Hi-Audio ~ Collaborative Online Music Recording


Hi-Audio is a free, open-source platform for musicians who want to collaborate on multitrack recordings over the internet.

Musicians can record their individual parts, upload existing recordings, and contribute to shared music projects without having to be in the same studio. Recordings are organized into synchronized tracks, making it possible to assemble performances from different contributors and locations.

The platform is also designed to support music research. Contributions help build collections of multitrack recordings that can be used to study music, develop audio analysis tools and advance music technology.

Features:

  • Browser-based multitrack recording and playback.
  • Upload and organize individual instrument tracks.
  • Collaborate with other musicians remotely.
  • Synchronize and annotate recordings.
  • Contribute recordings to music research collections.

Music Tribe Open Source ~ Opening Up Music Hardware


Music Tribe Open Source (MTOS) is an initiative from MUSIC Tribe, the company behind brands including Behringer, to make music hardware more open and accessible to developers and the wider music-making community. Its aim is to publish the hardware documentation and software foundations needed for people to develop alternative firmware, applications and new uses for its equipment. The idea is to move beyond closed, manufacturer-controlled instruments and invite the community to help shape what they can become.

Some of its most interesting projects include:

  • Behringer KICK (0700-AAM) – Source code for a standalone music production centre featuring a sampler, step sequencer, looper, touchscreen, effects and MIDI/CV connectivity. The repository includes its application, audio engine and hardware communication protocol.
  • Behringer IGNITE (0716-AAF) – A 64-channel multitrack sequencer with an internal sound engine, touchscreen, five MIDI ports and eight CV/Gate outputs. Its source and supporting system components are published, although the repository does not yet provide an official firmware release.
  • PRO-800 Firmware Packer – A utility for creating custom firmware update files for the Behringer PRO-800 analogue synthesizer, accompanied by main-board schematics and technical information.
  • Behringer BCR32 (0715-AAW) – Demo firmware, schematics and microcontroller interface documentation for the BCR32 MIDI controller, providing a practical starting point for hardware experimentation.

The projects are released under open-source licences, principally AGPL-3.0, and the organization welcomes contributions through GitHub. MTOS is a young initiative, but its significance goes beyond any individual instrument: it represents an opportunity for musicians and developers to gain greater control over the hardware they use.

Myspoti ~ Spotify Android Application


Myspoti is a Spotify app for Android that you install yourself. You sign in with your usual Spotify account, on Spotify’s own login page: Myspoti never sees your password. A free account is enough.

Under the hood, the official Spotify Web Player plays the music, hidden inside the app, with your phone’s DRM. Myspoti draws its own screens on top and drives it. Your plays are reported to Spotify exactly as in a browser: they count for the artists, in your history and in your Wrapped.

OnKey ~ Mac Singing Trainer


OnKey is a free, open-source singing trainer for the Mac. Play a song in Spotify, Apple Music, or YouTube in a browser, and sing along. The first time, you get the lyrics, and OnKey learns the singer’s melody when the song ends. After that, the notes scroll towards you, your pitch is drawn over them, and you get a score with a report on every line.

OnKey doesn’t provide, stream or download music. Your own music app plays it.

AudioRouter ~ Windows Visual Router


AudioRouter is a visual audio router for Windows 11. Draw your audio on a canvas: plug a microphone into a noise gate, an EQ and a compressor, send the result to Discord, monitor it in your headphones and record it, all at once. Stream game audio from your gaming PC to your streaming PC over your home network. Every route is a picture you can read, and every setting is live.
