< The issue: The sound volume of some instruments fluctuates too much between different song parts. >
<< The need: I want to be able to adjust the volume of guitar 2 IN THAT SECTION OF THE SONG (chorus 1) to be even with the overall volume of the song. So far I have only been able to adjust the volume of guitar 2 in the "Mixer Instrument Tracks" BUT, doing so adjust the volume for the entire song NOT just chorus 1. How do I adjust the volume of guitar 2 just for that specific part of the song (chorus 1)? >>

There's multiple ways to address your need using BIAB. Volume automation is one way but there are several different features in BIAB that can also do it.

BIAB has an advanced feature called the RealTrack Medley Maker that will not only allow you to balance the volume, but adjust the panning, and mute and unmute, of up to eleven RealTrack instruments at once. Further, because of the BIAB's reading ahead capability to determine what RealTrack data to select for each RealTrack instrument, BIAB is aware of forthcoming outro's of one instrument interacting with the second instrument beginning to play its intro prompting BIAB to automatically create a "smooth transition" between the two instruments.

A user can instruct BIAB to apply these processes and it will literally render a finished and arranged track that replicates exporting and editing multiple tracks in a DAW. It will create your arrangement automatically and it can be modified completely to meet the user's arrangement considerations.

Each of the 24 Mixer Tracks has the RealTrack Medley Maker. Each of the 24 tracks can hold up to eleven RealTracks, each independent from the other 23 Mixer tracks.

Most users don't know they can generate, control, manipulate, and program as many as 264 RealTracks, arranged as they have directed, all in a single render.

To load both guitars onto a Mixer Channel using the RealTrack Medley Maker:

Select the Mixer channel of one guitar. Open the RealTracks StylePicker, to open the RealTrack Medley Maker; It's located located in the RealTracks Picker under the Settings Button.

Then complete your arrangement for muting, panning and volume adjustment in that dialog window and BIAB will generate those two instruments in the arrangement you programmed.

I've attached a screen shot example of two instruments playing on the same Mixer Channel and alternating every four bars at first and then having four bars of silence between the two instruments alternating with each other.
