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.

FamiTracker ~ Freeware Famicom Music Tracker


FamiTracker is a free Windows tracker for producing music for the NES/Famicom-systems. The interface is based on MadTracker and should be easy to use if you’ve been using trackers before.

One of the features is NSF-file exporting. That allows music created in this tracker to be played on the real hardware, or even for use in your own NES-applications.

Some other features:

  • Full real-time emulation of all channels
  • Internal PCM to DPCM-sample converter
  • MIDI input devices are supported
  • NTSC & PAL modes are both supported

  • Offline lossless playback with full local library support for high resolution formats including FLAC, WAV, MP3, OGG, and M4A.
  • Easy built-in audio editor, downloading with effects or trimming 10-band & 3-band equalizer, and real-time DSP effects (speed, pitch, reverb, distortion).
  • 1-Click multi-platform playlist migration: Direct import and resolution of public playlists from Spotify, Apple Music, YouTube Music, and SoundCloud
  • Material Design 3 UI: Dynamic color extraction from album artwork, deep UI theming, responsive layout presets, and an integrated CSS editor

NeoBleeper ~ PC Speaker Music Maker


NeoBleeper is the world’s first AI-enabled tune creation software using the system speaker (aka PC Speaker) on the motherboard, inspired by the Bleeper Music Maker software that Robbi-985 (aka SomethingUnreal) developed around late 2007-early 2008 but abandoned in 2011 due to the fact that beeps were directed to the default sound device instead of the system speaker on the motherboard in newer Windows versions. NeoBleeper provides a more stable music making experience by solving the problem of system beeps being directed to the default sound device instead of the system speaker on the motherboard in newer Windows versions by accessing the physical port of the system speaker.

Ritmolux ~ Real-time Music Visualizer


A lightweight, real-time music visualizer built around one shared Rust core that turns a stream of PCM audio samples into GPU-rendered visuals. Two frontends consume that core:

  • Standalone app (Windows, macOS and Linux) — pure Rust (winit + wgpu), fed by the OS’s system-audio capture.
  • foobar2000 plugin (Windows-first) — a thin C++ shim over the core’s C ABI, fed by foobar’s own visualisation_stream (no loopback needed on that path).

The core is source-agnostic: it takes interleaved/mono PCM frames and does not care whether they came from loopback capture or foobar. That single abstraction is what lets one visual codebase serve both frontends.

WrzDJ ~ Disc Jockey Song Requestor

thinksynth ~ Modular Synth & Algorthmic Composition


thinksynth builds sounds out of a graph of DSP nodes — oscillators, filters, envelopes, delays and arithmetic — described in a small language and rendered in real time. Patches assign those graphs to MIDI channels, so one instrument can layer several voices.

Every node is a plugin, and the set that ships covers subtractive and FM synthesis, resonators, waveshaping and a range of filters. New ones are ordinary shared libraries dropped into the plugin directory.
