When more than 2 different styles are switched, the mixer instrument can only display the instrument name of the first style.
I found that the instrument name of the first style is also displayed in bar setting.
In this case, it makes me confused about the control of musical instruments in different styles.
I wonder if there is a better solution?
If you can switch the mixer name to the second style at the same time when the first style becomes the second style, it is best.

Updating the mixer information to accommodate multistyles has been suggested before. Perhaps PG Music will make that a future update but it is not currently possible.

It turned out that everyone suggested it very early. It's not finished now.
That's a pity.
Although I have just contacted the BIAB main program. But I can't see the names of different styles of mixer instruments, which gives me a headache. ha-ha

You are certainly getting into the deep end of the pool using mutiple styples in Bar Setting. As Jim mentioned what you are asking for, does not exist. However, there is a way to see exactly what styples you are programing into the Bar Settings.

Go into he Song Memo and select Bar Summary and it will list what you have done at every bar, including what styples you are changing.

I may not be able to operate. No tracks appear. no mixer name

How does this work?
Can you see the relevant track name

The Memo button displays what Realtracks are used in a song.

Navigate to a bar with a style change and press the Bar Summary button to display what style is loaded.

I tried, but I still couldn't.
C and f styles are different.
I took screenshots in C and f respectively.
As can be seen from the screenshot, the display of MEMS is still the same
I still can't know the track after the style change.

Up to now, I don't know how to view different styles of musical instruments

If I understand correctly, your "Guitar, Electric..." track is a medley, so it changes instruments though the song, but it always displays that "Guitar, Electric, Rhythm" string, it doesn't show each instrument as it plays.

If I'm right, one possibility is to put the instruments each onto their own track, or copy the RT to multiple tracks, mute as needed, and manually set the name and description. I realise this is not really what you want. Maybe someone else knows a better way.

How to copy RT to other tracks, and you can see this other track in bar settings.
thanks！
