The synclavier is my favorite instrument in the V collection, but I find myself frustrated by the necessity of always switching manually to "screen" mode when re-opening any instance of the plugin. This is especially vexing in a project with many instances of the Synclavier in that every time you save and re-open, they all revert to the keyboard view.
I only use the screen view (I'm sure I'm not alone in this) so a GUI system that always prioritizes the keybaord view is frustrating. The only time I use the keyboard is to adjust polyphony/legato/portamento settings, although frankly it would be great if those were added to the screen view (as far as I'm aware, those are the only settings that you have to use the keyboard view to access).
