Dexed is a multi platform, multi format plugin synth that is closely modeled on the Yamaha DX7. Under the hood it uses music-synthesizer-for-android for the synth engine.

The goal of this project is to be a tool/companion for the original DX7. Sound engine with 'float' value parameters, different waveform a la TX81z would be great but anything that goes beyond the DX7 should and will be a fork of this project. This is to keep the compatibility with the original machine.
