// ATTENTION! For better latency you have to redefine AUDIO_BLOCK_SAMPLES from
// 128 to 64 in <ARDUINO-IDE-DIR>/cores/teensy3/AudioStream.h
// If you want to test the system with Linux and withous any keyboard and/or audio equipment, you can do the following:
// 1. In Arduino-IDE enable "Tools->USB-Type->Serial + MIDI + Audio"
// 2. Build the firmware with "MIDI_DEVICE_USB" enabled in config.h.
// 3. Afterconnecting to a Linux system there should be a MIDI an audio device available that is called "MicroMDAEPiano", so you can start the following:
// $ aplaymidi -p 20:0 <MIDI-File> # e.g. test.mid
// $ arecord -f cd -Dhw:1,0 /tmp/bla.wav
