OK, I've been messing around with Music Creator 6 for four days and figured out most of the menus and buttons, but I have been having the following problems:
 
When I import a MIDI file created in Finale and play it, it continues to play after the end of the piece until I turn it off manually. Doesn't this thing recognize an end of track command?
 
When I view the event list for a track, all I see are the commands for playing individual notes. I don't see the controls for volume, pan, bank, and preset at the beginning that I see in other MIDI programs.
 
In Voyetra Record Producer (I miss that program very much; it doesn't work on 64 bit machines, and the company is out of business), there was a "Conductor view", where you could see and edit all of the global commands, like time signature and tempo. I can't find such a display in MC 6. Isn't there someplace where I can edit all of the event commands?

Try File > Open instead of importing MIDI. That may solve some of you issues.
 
One way to set tempo and time signature is the transport module (from: http://www.cakewalk.com/Documentation/defaultJA.aspx?Doc=Music%20Creator%206%20Touch&Lang=JP&Req=ControlBar.4.html)

Click "Q" to set tempo
Click "R" for time signature and key
 
You were in the correct view to see MIDI events with the event list.

MC will stop at the end of the song.  However, there may be material or data out further in the track that you do not see in your current view. MC sees it out there and makes that the end of the song.....
 
 
In a track there is a line....either solid or dotted. dotted indicates there is NOTHING past that point. A solid line indicates there is more data or audio further out in the track.... see this pic and look at the yellow envelope line.
 
Those are envelope lines but I believe there is a line in the center of every track that is better viewed in the clip view mode which also indicates the same thing. Makes it easy to know if there's something else in that track out to the right.
 
simply zoom out on your current view and or use the mouse to slide the project so that you can see out there. Find that data.... it can be a single midi note or a single tiny audio clip that somehow got placed out there...... delete it and the song will end in the proper place.
 
I notice that sometimes when I import "other" tracks to my DAW, they don't end up at the beginning.... something in them allows them to insert well off the screen.... I have to manually go and slide them back.
