MidiKit
MidiKit is a macOS MIDI file editor and batch processor for browsing, inspecting, editing, and fixing Standard MIDI files.
What is MidiKit?
MidiKit is a native macOS music utility for working with Standard MIDI files. It helps musicians, karaoke users, and MIDI hobbyists browse folders of MIDI files, inspect song information, edit events directly, and process large collections in batches. The app includes a browser that shows key details about MIDI files, an editor with unlimited undo and redo for event-level changes, and playback preview through Core MIDI or the Apple DLS Synth. It also supports filtering tracks and event types, editing lyrics and text-related data, and handling karaoke-related information stored in MIDI files. For larger libraries, MidiKit can batch-fix file attributes, convert or adjust files, and apply operations across multiple files or folders at once. It is designed for users who need focused MIDI file maintenance and editing tools on Mac.

Safety overview
Status: Mostly safe
MidiKit is a specialized MIDI editing app from Mixage and its behavior matches a music-production utility. Access to local files is consistent with its purpose because it opens, edits, and batch-processes MIDI files and folders. If you use MIDI playback or external MIDI hardware, check the app's MIDI and audio settings so output is directed to the devices you expect before making changes to files in bulk.
Recommendation: Keep MidiKit if you edit, inspect, repair, or batch-manage MIDI files on your Mac. If you do not work with MIDI or karaoke MIDI content, you can remove it without affecting macOS, though any personal settings or app-specific workflow conveniences may be lost.
