My core issue with presets is really about how the Kemper manages files. It doesn't behave like a regular computer where you can have one version of a file that can be accessed multiple times, by multiple files. You can't edit a preset and save it - you have to save as new file, and that new file can have the same name. You can have ten different Green Screams tweaked ten different ways, and not know which is the one you are looking for. You can't tweak a file in one place and have it show up in multiple.
I see no indication that this has been addressed. However, if the editor lets me see what preset a rig is using and gives me an easier and faster way of tweaking, and then copy/pasting it into multiple other places where it may be used, that MAY help make things easier. But, if I don't know everywhere that preset is used, and the system doesn't tell me, then there is a chance I will miss one.
Thats the core in a nutshell.
