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.

WhatChord is an interactive chord identification, key detection, and harmony exploration app. Identify voicings from live Bluetooth or USB MIDI input or manual note entry, follow the key as you play, then explore chords, scales, keyboard patterns, and harmonic context. It is optimized for speed, accuracy, and musician-expected naming, favoring stable, conventional interpretations over simple note-matching.

24seven.fm Covers ~ Radio Cover Art


Cover-art for the 24seven.fm family of internet radio stations — Streaming Soundtracks, 1980s.FM, Adagio.FM, Death.FM, and Entranced.FM. A shared, host-agnostic C++ engine drives three Windows front-ends plus a cross-platform core library:

ComponentDirectoryOutputBuild system
Desktop viewerdesktop/24sevenfm_covers.exe

MSBuild (.vcxproj / .sln)
Winamp pluginwinamp/gen_24sevenfm_covers.dll

Core librarylib/coverfetch static lib (cross-platform)CMake

All three front-ends share the same Direct2D renderer (shared/d2d_*.cpp), the cover engine (shared/cover_engine.* — cover preload, crossfade/flip transitions, remaining-time countdown), the options page (shared/options_*), and the networking/parse library (lib/). The library alone (lib/) is portable C++11 and already cross-compiles for Android/iOS.
