I'm assuming you have the hardware Kontroller, which you plug your guitar into, and then which plugs into the mixer. I would suggest that the issue is not software, but hardware. You most likely have a feedback issue, or possibly even a ground loop issue (although a ground loop wouldn't necessarily be a high pitched whine)

What I really need from you is a VERY detailed list of your gear, what is plugged into what, what kind of mixer you have, what kind of sound card you have, what cables go where, and even down to the power routing of your gear and your computer.

Also, we need what audio settings you have for each program.

It's very difficult to troubleshoot someone's problem like this over the internet, since you aren't there to go 'Oh, that cable shouldn't be plugged into that!' if you can't see the cable. So, having it in very great detail helps us a lot.

I'm blessed watching God do what He does best. I've had a few rough years, and I'm still not back to where I want to be, but I'm on the way and things are looking far better now than what they were!
