I think it would help if you listed some style examples. Tell us the main style of your song and the styles you're trying to use as substyles. There could be a couple things going on.

There aren't too many styles that were created with more than two dedicated substyles, but there are some... one example is _BOSALT+. This style has multiple substyles defined in the style. We made several similar styles and combined them into one.

What *you* are doing is defining the substyles in the song, starting with a style that only has two (A/B) substyles. so presumably you're trying to find similar sounding styles that could be used in different sections of your song.

Note that styles vary in how distinct their A and B substyles are. With RealStyles (all RealTracks) it's typically the Drums that are the main difference.

You can likely accomplish what you want without messing with substyles - You can make changes at any bar for example (F5) choosing different styles and instruments, muting instruments, etc.
