How can I edit the "Brand", "Author" and "COMMENT" properties of my original Massive X sound? I also tried using K.K.Software, but I was unable to edit the "Properties."

You also can't edit the bank field which is why whenever people add new patches or buy some from a third party they go into long and ever expanding list that gets increasingly hard to navigate (unless you user certain workarounds, as I have had to)
