I am curious about this feature. Right now I am using a Prime 4 but my SC-6000s should arrive this week (fingers crossed!)
For context - I’m impressed by this feature but it’s still muddying the low end on tracks enough that it’s not as supremely useful as I dream of.
#1 - Is the function the same on the Prime 4 and the SC-6000? Is audio quality on key-shifted tracks enhanced at all on the 6000, or is it the same if they are both using up-to-date firmware?
#2 - Does the fact I am using Mixed In Key for key analysis change it at all? I find MIK a lot more accurate than Engine’s native key analysis, so I run every single tune I own through MIK before import which means the track is tagged with that ey. But I am wondering if this then has an impact on the key-stretch at all?
For example a track that is in F-minor (4A) if I were to let it be analysed by Engine might come up as either a F-major or C-major (7B or 8B). If I then want to move this up one to F-sharp-minor (11A) is the software actually trying to move it from what it thinks is 8B? If so, it’s a much bigger jump than just one semitone, so I am wonder if that causes extra degradation?
… Or is that not really how it works, and reading the key from MIK is fine and doesn’t affect this feature at all?
