No Phil but there is always the option of using Scat Voices, and various Choir voices on a Keyboard in a Midi file. If you have an existing Midi file that you want to put Vocal Harmonies in, just load the midi into the Keyboard, go to the Mixing Console and under 'Track[s]' 1-16 just replace an existing Voice such as a Brass Section Voice or String Section with a Scat Voice or Choir Voice from the Keyboard. You will have to experiment with different Scat Voices/Choir Voices to see what "fits" and on what 'Channel' is the best Channel for a given Voice[s].
I am not aware of any program or innovation for embedding "Audio" Harmonies within a Midi file.
Another option is to play the Midi file on the Keyboard and run it out of the Main Outputs of your Keyboard and run the signal into your Computer's Sound Card. Use a Multi-Track recording software to record the Midi song and either sing along with the Midi song as it plays and records- (using the Multi-Track software) and by using a Mic and the Mic input of the Keyboard) and the Keyboards Vocal Harmony function "if it has one". The recording is recorded as a .Wav then you need to change it to an MP3. Thereby giving you an 'Audio' file with your Vocal's and Vocal Harmonies but of course it is now an MP3 and NOT a Midi. If you need it done completely in the Midi format then the only option that I know of is to use the Scat Voices or Choir Voices in an existing or New Midi file and edit and or save the file to include the Scat Voices or Choir Voices in the finished result.
Best regards,
Mike
PS: Maybe I'm way off track here as to what you really want to do. I guess I will need some clarification as to what you really mean when you say: "embed Vocal Harmonies into a Midi file"????
