Here's another script you can use with the Live Chord Input tool.
This will let you have different regions (chords) on another track.
You can then load the Biab Plugin on each track with a different style, key or tempo. You only need to solo the Master track in the Biab Plugin.
To get the Chords from the Biab Plugin into Reaper's regions use "Biab Plugin Chords" button in ReaTrak
to get the chords for current Plugin you to hit "Biab Plugin Chords" after you open the SGU or enter chords in the Plugin, save it then re-open it then "Biab Plugin Chords".

remove .mp4 from Marker region tracks GUI.zip.mp4 and unzip.

If you already have ReaTrak installed use "ReaTrak markers regions per track.lua" in Scripts\ReaTrak

If you don't have ReaTrak installed on Reaper use "Marker region tracks GUI.lua" if you only want the marker region script.

From here you will need to install Lokasenna GUI or via ReaPack
and run Library/Set Lokasenna_GUI v2 library path.lua

You can Import region/marker.csv by View > Region/Marker Manager

add regions or markers manually or import

select the track you want the markers/regions added to then hit the "Insert Marker Track" or "Insert Region Track"
select another track and do the same.
If you insert a new track make sure it's not in a track folder like the Regions and Markers tracks, if so just drag out.
