MusicStudent,
Thank you for bringing up Scaler. It is a very cool plugin to explore and experiment with chords, scales, inversions you name it.

Trygve, the new beta does detect chords from files. Scaler should be released within next couple of weeks. You can grab a demo to try it out.

I recently started a "wishlist" topic for PG to either update existing chord builder to something similar as most of the theory is already in BIAB or take a more universal approach and integrate chording apps, such as this one into BIAB workflow. Please support that if you find it
useful.

P.S. MusicStudent, are you using Scaler in BIAB or DAW? If BIAB, can you please share your setup/workflow?

The biggest downside for me is that this particular (great) program does not come as a standalone, only as VST.
