for panning inside the array, nothing other than WFS will give you a reasonable source image inside the room. often for ambisonics, you'd just xfade from the XYZ channels more into the W (omni) channel within a certain radius. same with VBAP - just pan all speakers. (or turn spread all the way up). Nick
