I think one of the points Duffman is making is that these don't behave like the pedals the presets are emulating. For instance, consider the Klon presets 1 - 5. They are all supposed to emulate the klon pedal with the same tone and volume settings but just adjusting the drive on the pedal; however, the kemper presets adjust three of the four kemper parameters to accomplish this feat. That's fine, and it's great that the tone shaping can emulate the nonlinear effect of adjusting the drive control, but that's highly non-intuitive if you want to emulate a klon pedal, i.e., the intuitive solution is that you choose preset 1 and just adjust the kemper drive parameter down to get a klon emulation with less drive.
It seems like it would be much better to have completely separate kemper pedal presets, like the green scream vs the plus ds, with fewer adjustable parameters that then behave more like the pedals being emulated. For instance, have a Klon preset with just drive, tone, and volume, and have the definition and slim down parameters controlled under the hood by the drive control to match the Klon pedal. Having presets like this does not preclude retaining the ultra flexible kemper drive in the current beta, but separate kemper pedals with controls that reflect the actual pedals would be much better from a user standpoint.
One other point I would add is that while this tone shaping is great, at the end of the day, the kemper drive is essentially just the green scream with a sophisticated eq added. While many pedals like the klon and king of tone are pretty similar to the TS808, others are not at all. For instance, the Boss SD-1 uses asymmetric clipping; whereas, the 808 uses symmetric. No amount of eqing will ever make the 808 sound like the SD-1, and it's a more than a little silly that the 808 and SD mid presets are identical (and the max settings are negligibly different) for pedals that are fundamentally different circuits.
