MIDI styles are included in the main Band-in-a-Box installation. These are styles that use all MIDI instruments. RealStyles are included in separate real* installers, along with the RealTracks instruments. These are styles that start with an underscore character in the StylePicker, and contain all RealTracks with no MIDI.

The Band-in-a-Box program is aware of all styles available (from PG Music), and so you can choose to show N/A (not available) styles by selecting the appropriate options from the 'Other' dropdown menu. A style can be N/A (missing completely, which is completely normal unless you have all styles ever made; they are hidden by default ), or it can be "N/A RT" which means that the (.STY) style exists by one or more RealTracks do not. This could be because you haven't installed them, or they aren't part of the package you have.
