I agree with this.

A problem with more than one style in a song, either using Medley Maker or style-change in Bar Settings is that the mixer does not display the instruments of the new style. The mixer only displays the track information for the first style, so I can't see or tweak or substitute instruments for the other style, which I should be able to do. In fact, it keeps the name of the instrument of the first style but plays the new instrument on that channel.

I assume the architecture of the mixer has only room for one main bass/drums/keys/guitars/etc.- of the first style - so it is impractical for it to keep swapping between them on the fly. Of course, with all-tracks-equal, I can manually duplicate a style by separately loading each instrument into a utility track so that they can all be seen in the mixer, and then mute or silence all the bars of each style when the other is playing, but this would be quite cumbersome and laborious, and all the information is known by BIAB to do this automatically.

SUGGESTION:

I'm wondering if when there are two or more different styles in a song, using either Medley Maker or style-change in bar-settings - an option for an automatic button to print the tracks of the new style(s) into utility tracks and appropriately mute both styles when the other is playing.

As already said, the information is available in BIAB, but it just needs to separate the tracks/instrument channels of each style to its own set of tracks (which of course can then be modified or substituted)
