Hit save with patches and harmonies after putting in the instruments you want in bar one. Note that some imported midi files even ones you find in band in a box format on the net have saved changes in the midi data and this will prevail even if you selected trumpet, if the midi file changes at bar 12 to clarinet that might happen.

Aftter filling all the check boxes you need to save, such as volumes etc. save the song that way. You can also change the sytle to the one you tweaked, and then save the song with that style. Some people have notice better results saving the file while it is playing, I've not had that problem.

You can also change the parameters in the song, choose a bar and press F5. As always my advice is to pick a song you don't want, play with it, mess with it, try things and make notes. Later do that with your real work, rather that banging your head against the desk later when it screws up.
