Matt,
I am aware of these. I tried using BIAB chord tool, but got frustrated for multiple reasons, which probably would be boring to list here.
"This would modify or replace that?"
That is a tricky question. Meaning, if the whole tool is re-designed then probably my request would be an addition. I doubt this will happen any time soon if ever. My request is for a much simpler tool. A reference library of lets say around 2,000 chord progressions.... (50-75 unique progressions X keys) with audition, copy and Favorite options.
I've done a bit of homework. Unfortunately there no straight forward alternatives in a form of VST. Why VST? So it could share same audio resource (for auditioning) with BIAB without opening one software and closing the other.
These are the closest "cousins":
Scaler - is more of a creative chord "sets" based on specific progressions and voicings - not really a reference library.
Odesi (Mixed in key) - Has to be connected to internet to work full time - YOU are the product.
"Chord Progression Reference" - Excellent and useful app - but only on Android.
1500 popular chord progressions by Walter-Stuart.(1950s e-book version) Very good reference, but you can't "audition"

1908 The Most Popular Chord Progressions 2023 physical book by Piotr Tadrzynski. Very similar to ^ .Nice paper book reference. Again, no audition for obvious reasons.
