MIDI Aid
The MIDI monitor
$0.99
MIDI Aid is back, completely rebuilt. A clean, technical monitor for every MIDI event your devices send.
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.
