Hello flashgordon,

You can find some styles (.STY) that use a particular RealTracks instrument by selecting the instrument from the "Assign Realtracks to track" window and pressing the Style Demo button. If you are referring to finding out all the MIDI styles that have a piano track, I'm not sure if there is a way to do that specifically - better to start with the genre that you're interested in and go from there.

In the StylePicker, there is a Prototype style listed in the title bar of the window. This is normally the style you currently have open. A caret symbol ^ before the style means that style matches the feel of the prototype (e.g. Sw 8), and an asterisk * means that both the feel and tempo match. There are also symbols that are part of the stylename, which help you recognize certain types of styles, like

+ (at the end of the style name) Multistyle
= (in front of the style name) Style with RealTracks - some MIDI, some Real.
_ (in front of the style name) RealStyle - all Real instruments.
- (in front of the style name) Style with RealDrums - all MIDI instruments except RealDrums.

There are some older conventions that aren't that significant anymore, because they are used in all styles...
~ style uses MIDI brushes
! Intelligent guitar style

By missing styles, if you are referring to styles you select from the StylePicker, you can get all the MIDI styles by getting a MegaPAK upgrade (or a SuperPAK/UltraPAK/EverythingPAK upgrade). This gives you all 77 MIDI styles sets. You can get all the RealDrums styles by purchasing a SuperPAK upgrade (or Ultra/Every), and you can get all the RealTracks by purchasing an Ultra or EverythingPAK upgrade. Band-in-a-Box. MIDI styles sets, RealDrums, and RealTracks sets can also be purchased individually.
