I'm glad you got it working !
With the soloist track sections you can lengthen them to add notes that you can't do with a consolidated wav file that you render in Biab.
You can also do that with the Drums track to get the exact track you need, then it can be made instantly into Stems.
You can instantly change FX <> Direct Input keeping the same riffs.
You can add new sections to any track with the other 2 scripts
Script: Import single frozen track or section SGU MGU to selected track.lua
or the easiest way with the GUI script
Script: Set SGU MGU single frozen track or section to import to selected track GUI.lua
with the GUI script you just copy all the files in the zip to the Scripts folder then load:
Script: Set SGU MGU single frozen track or section to import to selected track GUI.lua
