I have a bunch of profiles that I think are really great, but always wonder if there are other similar profiles that are just a bit better in some way. I also often think that a profile is good, but I'd like a bit more warmth, or sparkle or bite etc.
But with many thousands of profiles to search through its hard to know where to start looking, other than similar amps with similar gain. There are probably a lot of hidden gems that would be missed by just looking for other profiles of the same amp. I usually give up looking and go back to tweaking the profiles I already use, and to be fair the kemper is great for modifying a profile to get just what you want.
As I understand it a Kemper profile is a just set of parameters, so it should be possible for rig manager to sort profiles in order of their similarity to a reference profile. Rig manager would sort the rigs by total variance of the most dominant parameters.
As an extension of this idea of sorting by the profile parameters, rig manager could be extended to have columns for sparkle, bite, grit, warmth, fatness etc so you could sort by gain then sparkle then fatness for example. Obviously to do that would be quite a lot of work by the kemper team to come up with a set of common (rather subjective) terms for guitar tone and decide which profile parameters best fit most guitarist's understanding of what that term means. A bit of a minefield to get into, but the end result would make the rig manager and the rig exchange a lot more useful.
