MIDI Aid is a MIDI monitor: connect your MIDI devices and see every incoming event in one clean, technical view. Whether you are debugging a synth patch, checking a controller mapping, or just curious what your gear is sending, MIDI Aid shows you what is really happening on the wire. CAPTURE • Live event log with precise timestamps • Start, pause, and resume capturing at any time • Clear the log with one tap • Follow mode keeps the newest events in view UNDERSTAND • Every event decoded into plain language: notes with names and velocities, controllers with their standard names, program changes, aftertouch, pitch wheel, and more • Raw status and data bytes side by side with the decoded event • Hex or decimal display, your choice • Tap any event for a detail view including the full raw bytes FILTER • Focus on what matters: filter by device, event type, and MIDI channel • Channel events, system common events, and system real time events can be toggled individually • Mute noisy events like Timing Clock or Active Sensing with one tap DEVICES • Works with USB MIDI devices out of the box • Network MIDI sessions and Bluetooth MIDI devices set up at system level appear automatically MIDI Aid supports all 16 MIDI channels, running status, and System Exclusive messages. No account, no ads, no tracking. Your MIDI data never leaves your device. MIDI Aid only counts anonymously which features are used; a random install ID is added only if you allow it.

Verdict
The clearest difference is price: MGP at Free against MIDI Aid's $0.99. MGP also leads on update cadence (every 4 days vs every 7 months). MIDI Aid's advantage is in-app purchases (none vs 4). On ads, device support and iOS requirement there is nothing between them.
