MidiKit
MidiKit is a macOS MIDI file browser, editor, and batch processor from Mixage Software for inspecting, editing, previewing, and converting MIDI data.
What is MidiKit?
MidiKit is a macOS application published by Mixage Software for working with Standard MIDI Files. It combines a file browser, detailed event editor, playback preview, and batch processing tools in one app. Users can inspect MIDI metadata, edit native SMF events, filter tracks and event types, and preview files through Core MIDI or the Apple DLS Synth. The app also includes MIDI input and output settings, a Music Device window for SoundFont-based playback configuration, and tools related to karaoke and chord data handling. Mixage documents support for General MIDI workflows, batch fixes and conversions, and editing functions with unlimited undo and redo. Mac downloads are provided directly by the publisher for macOS 10.13 and later, and the product page lists native Apple Silicon support.

Safety overview
Status: Mostly safe
MidiKit is a legitimate publisher-distributed music utility for macOS. It handles user-selected MIDI files and playback configuration rather than core system functions. Normal caution is still appropriate when opening downloaded MIDI files from untrusted sources, especially if they come from unknown archives or are used in batch operations.
Recommendation: Keep MidiKit if you edit, inspect, convert, or preview MIDI files on your Mac. If you do not work with MIDI content or no longer use Mixage music tools, removing it is generally reasonable.
