Hey Cliff
@FractalAudio, I found a bug in the 'Balance' control in the Amp block. I use this control in quite a few of my presets. I had a few emails from clients that had experienced issues with many of my presets during some of the beta versions. I usually don't upgrade until there is a stable release, but I upgraded to 'Q10 rc#2' to see what the issue was that was being reported using the latest release.
When the Amp block 'Balance' parameter is set to center or left, and outputs evenly to both sides. When set to right, there is no output at all.
