A Very useful app to monitor OSC & MIDI messages in a network. It would be great if they have added more data protocols like the UDP, TCP,MQTT & ArtNET.

The best MIDI monitor on Android I came across ! Two things: The touch interface is not very responsive. I am having trouble setting the preferences with tick boxes not ticking easily and unwanted scrolling. The other feature I would love to see is to have the actual musical note displayed in NOTE events and not just the number. To keep it two characters this could be "Tracker Notation": C4 is a C4 and c4 is a C#4.
