Is your feature request related to a problem? Please describe.
Some MIDI files are strangely slow compared or off-key from the real song that they're based on.

Describe the solution you'd like
It would be nice to be able to adjust the tempo and pitch of the Transmitter to correct that. Not sure that it needs to save those settings on a song-by-song basis or just apply them to the full Transmitter. TBD.

Describe alternatives you've considered
There isn't one unless you edit the MIDI in an external program.

Additional context
Lots of MIDI playing programs support this feature. I.E: vanBasco's Karaoke Player
