Hi Mcoyle, maybe this helps you as well, this is an answer I got from a Reaper user:
This works fine for me, although it would still be nice to have TC in the midi editor one day...
>> does not seem to be a way to see hr min sec frms in the midi editor and it makes sense to me that one would mostly not want to ...
That said, you can set the main ruler to that time code, and then select any midi item and hit E key [the default unless you changed it] to show that item in the 'Inline Editor' view... then you will see the notes in relation to the main ruler time code and can edit them <<
