As title suggests, found this out by noticing in Voxengo SPAN (Hi Res Mode) that the frequencies above 17000 were being let through and noticed in LP64 EQ that the settings had changed from how I had them saved in a preset! When at -inf frequencies are not let through, which what I wanted.
In fact when pressing play in X1 (win 7 x64) it resets any of the points that are set to -inf back to -24, it also happens if close the plug-in and reopen it. This happens whether aero is on or off.
