A few more details to stimulate the talent in this forum into helping me figure out best practices to achieve my goal. As a beginner (both to BIAB and bass playing) I am thinking two approaches to it, but don't know if I am on the right track or if there's even a third and better approach.

Goal: Create practice tracks for mainly bass, but other instruments as well.

Scenario 1:
1. Pick a song from a sheet music book dedicated to bass covers
2. Select an existing BIAB demo style that resembles that song and change the chord structure to reflect the book sheet music
3. Isolate (freeze) the bass track and punch-in the bass notes according to the sheet music book
4. Play and practice with the new bass line

Scenario 2:
1. Select a new BIAB chart (with Blank style)
2. Isolate the bass track and enter the chords progression followed by the individual notes in editable mode
3. Save and use that bass track with a BIAB demo style that resembles the chosen song

What would be the least time consuming and easier to put together? Other?
Thank you
