This is variation of the standard branch of the MicroDexed 6-operator-FM-YanahDX7-Synth by Codeberg-dcoredump. It replaced the Teensy Audio board with an inexpensive PCM5102A module, and used a 6N137 for the Midi input. Changes made to the config.h file are included here, and the firmware hex file that can be uploaded to this Teensy 4.0 synth using the Teensyloader are also included here.
It is currently constructed on a breadboard and the connections between the Teensy 4.0 and the SDCard module Front and Back, the two encoders, the PCM5102A DAC and the LCD are given in Connections.txt. The changed DAC connections are not described in config.h and had to be traced from a Teensy 4.1 to teensy 3.6 adapter board from another repository. The USB Host connection (D- and D+) for a USB Midi Keyboard are taken from the two bottom pads underneath the Teensy 4.0.
