For some reason the midi tracks have disappeared in my track view but they are still in my console view.  They still are playable but I cannot edit them in the track view.  How can I get them to reappear in the track view?

Welcome to the forum.
Which version of Music Creator do you own? Check the Track Manager In older programs, you access that by pressing the M key. In newer programs, you click Tracks above the Track View, then select the tracks you want to see. It seems to be keyboard shortcut H.

It is Music Creator 6.0 Build 50.

Hi, I also have MC 6 and I tried to reproduce the issue, but the Track Manager option is grayed out, on the Strips Menu / Console View.
 
I also checked the online help for MC 7 and it should be possible to hide some tracks hitting Ctrl+Alt+H, on the Track View. But occurs that after that, I couldn't bring them back, by hitting Shift+H 
Maybe I'm missing something?
 
Best regards

track manager was not available in some versions of MC 
 
I think I remember that there was a bug where a track could be hidden but since the track manager isn't available you couldn't undo it or bring the track back visible.  IIRC cake made an update based on that problem.  make sure you're using the latest version, which I can't seem to find right now.

other than that, using SHIFT-H should bring all tracks back to view.
