>>>"Can explain how this is done? Is there a video explaining this? I would love to know how to do this! (each track having it's own chord grid)"<<<

Simple Explanation:

Open first sgu file in RB
Save file as RB seq
Generate RB tracks with instruments you want to follow the sgu 1 chord chart.

Open your second sgu file in BB so you can note the differences between sgu 1 chords and sgu 2 chord chart. (This is for reference, changes are made in RB)

In the chord chart of RB, make the changes in the chord chart so the RB chord chart matches the chord chart of sgu 2.

Select and generate the Realtracks that you want to respond to the sgu 2 chord chart. Do not use the generate all function, because it will of course Generate All which will alter the audio files that were previously generated to the sgu 1 chord chart. To avoid this, select and generate these either one at a time or you can also select multiple tracks (which would be the instruments you want to follow the sgu2 chord chart.)

You can easily continue to build as many tracks as you want by repeating the above process.

Your RB song now has some tracks that follow the sgu 1 chords and additional tracks that follow squ 2 chords.

It's not as hard as it appears and an easy and simple way to practice before you are working on a actual project is to write a simple chord chart in a new RB project. Select and generate a track that follows that first chord chart. Once that track has generated, make any change you want to the chord chart, select and generate a second audio/midi track and it will generate a track that follows the changes you made. Doing this will let you see exactly how RB responds to your changes.

All that to say that in RB create or import a chord chart, generate the tracks that will follow that particular chord chart.

After generating the tracks, make whatever changes or additions you want to the chord chart.

Select and generate new instruments that follow the altered chord chart. Each track now has its own chord grid.
