Well, I will try to download the Catanya plugin a bit later this morning, and will try to see what's what with it in X2.
I am a bit confused as to why you refer to this as "multiple VST's using midi out", as it seems to be more of a question of using multiple instances of this particular plug in. Maybe I am not getting something.
I have thus far in X2 had projects with as many as 5 instances of the same plugin (Kontakt 5), with no problem, and also multiple copies of Rapture - using arpeggiated presets, with no trouble - for whatever the worth.
Anyways, I will let you know what happens in a couple of hours or so. I have been up for many hours now, and it's nappy time.
