# 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 See example sketch. ## API AudioSynthDexed(uint8_t max_notes, uint16_t sample_rate);
