/*************************************************************************
* This demo uses the BAGuitar library to provide enhanced control of
* the TGA Pro board.
*
* The latest copy of the BA Guitar library can be obtained from
* https://github.com/Blackaddr/BAGuitar
*
* This demo will provide an audio passthrough, as well as exercise the
* MIDI interface.
*
* It can optionally exercise the SPI MEM0 if installed on the TGA Pro board.
