I've created a setup to automate rig and effects changes in my Kemper via midi, sent from Ableton Live.
It's possible to automate CCs in Ableton Live directly, but not very practical: you have to go dig for them inside a MIDI clip and manually switch between the different CCs you want to edit, so it's very hard to get an overview of all the automation going on in a song.
That's why I've created a dedicated Kemper controller in Max For Live that more or less mimics my old FCB1010's layout and functionality. If anyone's interested, you can download the latest version here.
Just drag it into a midi track (that points to the correct midi output and channel, of course)!
As you can see, there are toggles for stomps and effects, buttons for the five slots within a performance, up and down buttons to go to the next or previous performance, 26 numbered buttons for direct access to specific performances, dials for delay and reverb parameters just like those dedicated knobs on the Kemper, and sliders to mimic the expression and volume pedals.
The best thing is that all of these buttons, toggles and dials represent named parameters that can be automated in the channel's arrangement lane directly. In turn, they operate the relevant CCs (so you never need to worry about CCs anymore).
When I started this, I'd never worked with Max For Live before so it took me some time to figure everything out, but it's definitely a very powerful tool.
Update (March 2017): After not using this device for a long time (because my band stopped using Ableton Live for playing, um, live), a question on the Kemper Users Facebook group reminded me of it. I've now updated it by adding a morph slider! I've edited this post and replaced the screenshots by more recent ones.
Update (June 2020): Wow, has it been this long already? Anyway, I finally added a couple of more updates: the ability to select the full range of Performances (1-125) and a full range of looper control buttons. Check my post further down in this thread for more details. The download link is still the same as above.
(If you prefer the 2017 version, it can still be found here.)
