I think you might be better using a MusicLabs guitar like RealGuitar RealStrat ... can can change the position manually or by keyswitch, you can create your own strum patterns or finger picking and play them from a track in the DAW. It also has Midi Out so you can send the midi to another virtual instrument.
You can use it inside Biab Using Midi Chord Output to VSTi Inside Biab
