I would search eBay for a Roland guitar pickup and synth it wouldn't be too much more in price and will pick up all the strings and notes at the same time accurately.

Get LoopMidi EDIT:(or use IAC bus on a Mac).

set it as the Midi Guitar 2 output and the input in Biab or RealBand.

Realband would be easier as you can have more tracks and drop in anywhere.
