In the case of most of my waves enigma, Renoise crushes everything into a tiny little window. In reaktor, my synth is cut off. Is there any way to resize these ext. editor windows? Reaktor’s situation is pretty annoying, but Enigma is nigh-unusable in that state.
I’ve seen this, it can be especially annoying in respect to designing instruments/fx.
The solution I’ve found on NI’s own website via google is:
in Reaktors window go to the menu (dropdown arrow thing) => view => optimal size (near the bottom)
You can specify max size the window will take for “optimal size” in the prefs.
If VST windows could simply be made resizable… whooo! 
PS. also the magnifying glass (inspector) button and the state of the edit button sometimes do something with the real estate the actual instrument / design window is getting.
Aha! Messing with optimal/large size isn’t a perfect solution, but it’s a massive improvement and doesn’t mean I need to move the instrument panel around very often, so that’s a big help. Thanks!
Yeah, I can’t even resize the VST windows with external programs! It really is a shame we can’t do that normally. It seems like such a simple thing to be able to implement.
I’m not sure if the host can dictate the frame-size of the plugin its dialog at all. If they could, i’m not even sure if the plugin can be made aware of what the frame size is.
Usually, a program calls a function within the external library and that function builds up the dialog from itself, because the library developer has designed the GUI thus knows what the frame-size should be at least.
Resizing a DirectDraw frame is something different than resizing a common dialog on the Windows world (meaning directdraw frames are not easy to extend or minimize by mouse actions). I’m not sure if there are similar methods on Mac and Linux. High portability comes with restrictions.
