Welcome to the forum!
Looking at getting a controller for the kemper. I see some buzz about this controller. A few questions
1. Is there a lot of setup to make it work with kemper? What all has to be programmed? Plug and play or some ground work need to be done ?
It's not plug'n' play. Installing the eprom is easy though and is covered in the installing instructions that come with the eprom.
2. What chip is needed to get maximum performance
FCB-1010 Foot Controller ( OS/Firmware UnO Revision
FCB-1010 Foot Controller ( OS/Firmware ver 2.50
The UnO chip is the best at the moment. The manufacturer, look up http://www.ossandust.be, is working on a specific KPA eprom at the moment which is said to be available very soon,
3. Any detailed instruction on chip replacement and what to do after replacing it
Covered in the instructions.
4. Can this controller not only change profiles but also turn a stomp or effect on or off. I assume it can but has to be programmed?
Yes.
5. Is there any documentation anywhere that is used when programming as a guide. Kemper midi doc and FCB 1010 Manual only?
Yes, there's a doc with the controller change numbers that are fix in the KPA.
Programming the FCB best is done using an editor.
I recommend the one from the UnO chip manufacturer, which can be found under http://www.lg-fcb.com
