Creating macro pages?

I can’t find anything on that. Is it possible to create your own macro pages in Halion 4 ? Everything is customizable in Halion 4, but i can’t find any documentation on how to edit/create macro pages…

Programming/Skripting would be no problem, but where can i do this?

As far as I know, there is no way to create your own Macro pages. The Macro pages are only for already created content which contains Macro pages such as the Halion Sonic/SE presets as well as any additionally purchased packs from the Steinberg site. I wish there was a way to create your own, perhaps this feature will become available in a future release.
