Thanks for this. I wonder what the difference between halion sonic 3 and 3.1 is. There is no info on that.
Under the HALion 6 update the version history pdf mentions Sonic and notes the following:
HALion Sonic allows now to export presets to an arbitrary folder on the system outside the MediaBay. The save dialog allows to specify MediaBay tags so that the preset can later be added to the MediaBay including all relevant information.
It may be this that requires the version refreshment.
