Haven't been on the forum for a couple of weeks and all the information shared is quite informative. As far as the workaround Jerry suggested, I am not sure that it will fix the main problem I am having and that is that the other softsynths, plugins, vsts or whatever you want to call them become unusable because they don't know which output to use. As far as dragging the midi from ez1 track to ez2 track does that allow me to edit and add things using ez2? Though if it is still screwing up all the other plugins I can't see that happening.
Unfortunately the answer for me was to just uninstall ez2 and keep using ez1. I was hoping that I could install ez2 on an old computer (vista) with an old version of sonar would allow me to create audio files and then import to the win7 computer. However ez2 is not compatible with vista.
Though I can't really afford it right now I would give consideration to upgrading to Sonar x3 if I thought all this could work together but to the best of my understanding the problem would still be the same.
As far as Sonar and Toontrack working together I can only quote Rodney King (google it if you are too young to remember this) "can we all get along".
