What is QMidi?
QMidi is a native macOS karaoke and multimedia player designed for users who work with MIDI files, karaoke tracks, backing tracks, and song libraries. It helps singers, musicians, and karaoke hosts play and organize media in playlists and library views while showing synchronized lyrics, chords, markers, and CDG karaoke content. The app supports MIDI playback, many audio and video formats supported by macOS, full-screen output, and a mirrored display on a second monitor for performances. It also includes tools for pitch and time adjustment, lyric and chord editing, karaoke text formatting, and export features such as karaoke-to-movie conversion. QMidi is published by MIXAGE di di Gleria Bruno and runs on modern versions of macOS, including Apple Silicon systems.

Safety overview
Status: Mostly safe
QMidi is a legitimate consumer media application for macOS focused on karaoke, MIDI, and backing-track playback. Permissions related to media access, file access, second-display output, or MIDI device use are consistent with its purpose. As with any app that opens downloaded media files and uses external MIDI devices, install it from the publisher's site and keep the app updated. If it stops launching or behaves unexpectedly, resetting its preference file may clear corrupted settings, but doing so can remove saved app preferences.
Recommendation: Keep QMidi if you use your Mac for karaoke playback, MIDI practice, backing tracks, or lyric and chord display. If you no longer use it, removing the app is optional and mainly frees disk space and related settings files without affecting macOS itself.
