* DX Synth engine (as part of Dexed): Raph Levien and the msfa team
* PPPlay : Great OPL3 implementation, with documented code :D
## Dexed comes with 3 engine types :
* Modern : this is the original 24-bit music-synthesizer-for-android implementation.
* Mark I : Based on the OPL Series but at a higher resolution (LUT are 10-bits). The target of this engine is to be closest to the real DX7.
* OPL Series : this is an experimental implementation of the reversed engineered OPL family chips. 8-bit. Keep in mind that the envelopes stills needs tuning.
