Hi
I’ve posted several times on audio detection here, and Scaler operates in a different way to other apps in this area. It’s internal structure means that there are somethings it doesn’t do (by design, effectively) and some things that it does do much better than many alternatives
I posted a couple of links to some of my earlier postings here
I use it all the time for pulling progressions out of multi-bar synth sequences in DUNE, Omnisphere and others, and my workflow is described in the link above. As you see, my take is that it’s better at picking up higher chord extensions than most, but its lack of time awareness and way of dealing with single notes means more work than others. (BTW, the latter two are not bugs - it detects changes in chord sequences)
