If you have the 2025 Ultra PAK or the 2025 Audiophile you have 1,015 PG Music created MultiStyles. See the screen shot below. PG Music identifies MultiStyles by adding a + symbol at the end of the style name.

Here is what the Help file says about MultiStyles:
Quote
Band-in-a-Box MultiStyles are styles that can have up to 24 Substyles; original Band-in-a-Box styles had two Substyles, "a" and "b." Band-in-a-Box MultiStyles typically have four Substyles, but may have up to twenty-four, selected by using part markers "a" through "x."

You can easily make your own MultiStyles, either from scratch, or combining parts from existing styles to make a MultiStyle. For example, if you have 10 favorite Country styles, you can quickly make a single MultiStyle that has 20 Substyles available within the same song.

There are 2 types of MultiStyles

1. MultiStyles in styles, working for every song (e.g. NR_CURR+.STY Nashville Rock Current MultiStyle).

2. MultiStyles for a specific song only.

MultiStyles in Styles ("+" Styles)

Styles can be made that have multiple Substyles, and you can choose the various Substyles using the letters a, b, c, d, etc. up to "x" for 24 Substyles.

Our naming convention for MultiStyles is to use a + sign at the end of the style name. For example, MyStyle+.STY would be a MultiStyle.

You can use these substyles easily. Just open the StylePicker and filter the styles list by "+.sty."

The point Charlie was making is Realband is limited to using just the first style of a MultiStyle. Not mentioned above is the DAW plugin is also limited to using the first style of a MultiStyle.

A good example of how a MultiStyle can complement a song is given in the Memo textbox of the highlighted style in the screen shot.
