+# Synth_Dexed
 
+Synth_Dexed is a port of the Dexed sound engine
+(https://github.com/asb2m10/dexed) as library for the Teensy-3.5/3.6/4.x with
+an audio shield. Dexed ist heavily based on
+https://github.com/google/music-synthesizer-for-android .
+Synth_Dexed ist SYSEX compatible with a famous 6-OP FM synth and is used in MicroDexed (https://codeberg.org/dcoredump/MicroDexed).
+
+## License
+MicroDexed is licensed on the GPL v3. The msfa component (acronym for music synthesizer for android, see https://github.com/google/music-synthesizer-for-android) stays on the Apache 2.0 license to able to collaborate between projects.
+
+## Credits & thanks
+
+* Dexed engine by Pascal Gauthier (asb2m10)
+* DX Synth engine (as part of Dexed): Raph Levien and the msfa team
+* PPPlay : Great OPL3 implementation, with documented code :D
+* Thierry Pottier: for extreme testing, discussing about different options, images and many good suggestions for UI handling
+* Lars Pelz: Testing and documentation
+* Mark (@positionhigh) for testing
+
+## Usage
