Feature Request: Change Tempo after OMD Convert

[Majumafoo]

As it is, it seems we are unable to change the tempo of songs after converting .midi files to .omd
It would be a nice feature to have.

Looking through the code here, (starting at line 174) it seems that the program is intended to reflect tempo changes, but I believe this only happens at initialization.

I've created midi files to test this with both Midi Editor, and Pro Tools and confirmed that this issue is not a deficiency in Midi Software.

Edit: I've done some more testing and have these files available for validation.
