(Every controller I know of or have used since like 2010 has done this.

Since device mapping, and specifically the instrument rack macros (what used to be 'groups'), is dynamic and not assignable via CC, any idea how to go about this with the Keylab mk2? Nor does it make sense to midi map each knob individually, since I'd be doing that every time I drop in a new device. I've read a bit about custom scripts in Ableton, but I'm guessing that this would then override the rest of Arturia's mapping, and I'm not sure I want to do that. In DAW mode, they seem to be hardwired to mixer pan (really? who needs this?) and in User mode, they can only be assigned CC numbers. But I can't seem to find a way to map the knobs on the controller to Ableton's devices.

But I'm finding one thing about it that is driving me batty, and I don't know wether it's an Ableton thing or an Arturia thing. I have the Keylab mk2, which in the short time I've been using it seems to be a pretty terrific midi keyboard/controller.
