MicroDexed
MicroDexed is a port of the Dexed sound engine
( https : //github.com/asb2m10/dexed) for the Teensy-3.5/3.6/4.x with audio shield.
Dexed ist heavily based on https : //github.com/google/music-synthesizer-for-android

# error This version 1.2.7 the code does only work for Teensy-4.1 with enabled FX. It was to difficult to support all other flavors of the Teensy universe in one code base.
# endif

# include "midinotes.h"
// If you want to test the system with Linux and without 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 "MicroMDexed", so you can start the following:
// $ aplaymidi -p 20:0 <MIDI-File> # e.g. test.mid
// $ vkeybd --addr 20:0
// $ arecord -f cd -Dhw:1,0 /tmp/<AUDIO_FILE_NAME>.wav
//
// Tools for testing MIDI: https://github.com/gbevin/SendMIDI
// https://github.com/gbevin/ReceiveMIDI
//
// e.g.:
// * sendmidi dev "MicroDexed MIDI" on 80 127 && sleep 1.0 && sendmidi dev "MicroDexed MIDI" off 80 0
// * sendmidi dev "MicroDexed MIDI" syf addon/SD/90/RitCh1.syx
// * amidi -p hw:2,0,0 -s addon/SD/90/RitCh1.syx
//
// Receiving and storing MIDI SYSEX with Linux:
// amidi -p hw:2,0,0 -d -r /tmp/bkup1.syx
//
