MIDI receiving continously in serial monitor - "Message, type=248, data = 0 0"
I built the MIDI circuit for 5-pin DIN here: https://www.pjrc.com/teensy/td_libs_MIDI.html
This circuit worked well for me the last time I built it, but this time I am getting this message continuously: "Message, type=248, data = 0 0" It looks like a timing related message? The notes do come through correctly such as "Note On: ch=1, note=40, velocity=79" and I can use the notes to do things like trigger LEDs, but I don't think I am supposed to be receiving any MIDI Message continuously. Typically RX should be continuously high and only when RX is pulled low is a message started, correct? The code is just the "Example Input Program" according to the same link/page above.
I know I need a scope - it's the first thing I plan to buy when I can afford one.
