Not only since upgrading have I experienced the same results as you stated, but even more so I get random instruments playing notes I don't even have in the score. Worked perfectly, then upgraded to newest version and it all fell apart. I have had to do single parts only now and have to put my DAW in solo mode per track or it does some pretty annoying things.
On my Mac in Logic using VE3 locally it will literally play one part through every channel of Logic. So with only notes on violins, it will spam all my channels (all 16 that are part of the same VE interface). I can't even use it atm. I have to freeze all my tracks to even playback. When I use VE3 over network, it will play random notes on all my instruments as well. Basses will punch out a few notes, then cellos, etc even without them having any written notes to play. It's very bizarre. For now I have had to save to another project and use single instances of VI just to get parts recorded in for playback.
