Thank you for responding, saxmand. I was beginning to worry that this would another response where I just give up. Then somebody responds 1 year later, but I have by then forgotten the post...
On Panagement, they have a reverb, but I don't use it, preferring the algo reverb I have on my bus. I use a slider to move instruments back and forth. but I have a hard time deciding just where to put them. I tried using Garritan's positions in the Stereo Stage feature on the Aria player, but those percentages are way too deep. but if I reduce them by 50-75%, they seem to work. For example, GPO has percussion at 90%. There are some other oddities, such as violins 1st are at 20%, 2nd violins are at 50%.
I was hoping that someone is using that plugin, and could help me out with the settings. But it appears that most here have moved on to Synchron, where this is predetermined. Maybe I need to join the VI Control forum, I'm sure I would get some responses there. In fact, that is where I heard about this plugin. but that forum is such a time-sucker. Too many way too long threads about AI and other such things. So I prefer to just lurk there.
