Is there any sort of MIDI hex viewer that will show me the contents of a file both in hex and with the corresponding MIDI info next to it, in real time?

Tracing some issues in a very large file, and I can look in my hex editor, but then need to take a lot of time mentally converting the hex in to what it's actually doing.  It would be super handy if I could just look and go "Yup, that's where it went haywire".
