Adding a stereo DI (Radial Pro D2) with a ground lift has solved most of my laptop problems. I use an 8 channel line mixer for my keyboards/laptop input (ART MX822), which solves the stereo/mono summing issues, and put the DI on the end. The lift works well when the power (everywhere) is sketchy.
I don't always use the laptop (only in our Floyd tribute for SFX and Cynthia (EMS) for "Shine on" "On the Run", etc). My goal is to move all sounds/VSTs OFF of the laptop and never use it out live again.
Cheers everyone, my first post! I love this forum. SO helpful.
