Hi Matthias!
Halion 6 looks very promising. I do have a question relating to the Macro Page Designer and the Library Creator. I was quite excited at first, but I think I got ahead of myself there a bit:
After you create a UI with the Macro Page Designer for, lets say a sampled instrument, you then use the Library Creator to export it in some way or form. Its not quite clear to me if the Library Creator creates a library item / Instrument only for use in Halion Sonic 3 / Halion 6 (closed system) or actually creates a stand-alone VST2/3 Instrument for use in other applications that support VSTs.
Can you create standalone VSTs with Halion 6?
Cheers.
