Sometimes I'm out in the wild and I encounter something that I want to profile but I don't have my Kemper with me.
I'd like to see a little pocket (or smaller) doodad that just generates and collects the impulse response with a single in jack and a single out jack on it. You can then connect to your Kemper when you get back and the Kemper will process and generate the profile from the result. Ideally battery operated, no phantom power, just super basic.
Failing a dedicated unit even just an app on the phone that generates the sound, then within rig manager an "upload profiling take" option that accepts an audio file and will generate a profile based on this.
Obviously it will have all the expected caveats and limitations, you can't refine etc, but it would be super convenient for when you're not the office.
