Amendment to C++ code on github (MIDI related)

Hi, I'm looking for someone who can make an amendment to the source code of the Misa Digital Instruments' Kitara which is posted on Github here: [login to view URL] Basically what I'm looking for is the ability to play multiple notes simultaneously on one string. The Kitara, as it is now, mimics the behavior of a real guitar in that if you press 2 buttons on the same string, only the higher pitch note will sound. I'm looking to be able to play whole chords only on one string. I only need this function to be available for MIDI output and it doesn't have to deal with the in-built synth, it would also be nice to have a switch in the system settings that turns it on or off. SDK can be found here: [login to view URL] I would then just require some assistance in loading the new code onto the Kitara instrument itself which connects to the computer through USB.
