Is your workflow/experience with this tool markedly different from what Mario said
Yes.
Scaler, for me, was not meant to replace BIAB. And, I never wanted Scaler to "do more for me". Instead, I wanted BIAB to do less, and Scaler to allow me to do more -
for myself. After decades of using BIAB, I reached a point where I was letting BIAB perform too much of the creative process for song writing. I no longer wanted to pick a style, load the demo songs, and have the chords laid out in a canned progression. Scaler helps in the creative process by helping "ME" to write the progression. Nor did I want the entire accompianment to be added to my chords by picking and pluging RTs into the song. I came to the point where I needed to get more of me in my music. That dictated less of BIAB. Scaler was helpful for me in making the needed transition away from BIAB for me in order to grow musically.
I am not trying to sell Scaler (although it might sound like that

). And I also am not trying to bad mouth BIAB. I still use both these tools, for the inspiration they provide.
In recent times, I have been able to bring more of me into the creative process by limiting my BIAB content and employing alternate tools, including Scaler and all the virtual instruments provided by Kontakt along with aids to write my own music. Its a long term process... but I am making progress.
Hope that clarifies my workflow strategy.
