< My fantasy goal is to simply see (NOT hear) the bass notes I want as a visual guide for me playing along with the recorded stem bass part muted. This would complete my fantasy bass song practice file which would show: >

An audio file (actually, any media BIAB recognizes ) converted into an Artist Performance File can have transcription allowing you to see notation, tab, or the midi data in Piano Roll or the Guitar Fretboard which can also display the Bass fretboard.

It's my opinion that:

< -Accurate chord chart of a commercially recorded song with the measures moving along as the song plays
-The recorded song split onto stems.
-The bass stem muted so I can play along outside of BIAB
-And then per my question, see the desired notation of notes for the bass part that I can refer to in real time as the chord chart progresses (so if I forget a bass note, I can see it in the notation) >

is possible using the Stem Splitter, ACW, Artist Performance File feature, and BIAB.
