/*************************************************************************
 * 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 demonstrates how to override the default AudioEffectDelayExternal
 * in the Teensy Library with the one in the BAGuitar library.  This is necessary
 * because the SPI pins in AudioEffectDelayExternal are hard-coded and not the
 * same at the TGA Pro.
 * 
 * Simply replace AudioEffectDelayExternal with BAAudioEffectDelayExternal
 * and it should work the same as the default Audio library.
 * 
 * This demo mixes the original guitar signal with one delayed by 1.45 ms
 * the the external SRAM MEM0 on the TGA Pro
