Hi cajun,
Are the brass and piano tracks not saving or are they saved but not playing on the keyboard?

If they are not saving they may be muted thus they are not included in the save. You may also want to try putting the piano on channel 3 and the brass on channel 7 and see if that helps. You mentioned tracks but what are the midi channels associated with those tracks?

If the tracks are indeed saved make sure the saved track midi channels match your keyboard midi channels. If they do then check the tracks for CC numbers 7 and 11. These CC numbers control midi volume.

Let us know how you make out. Plus if this didn’t help a little more information would be a great help.
