Dexed Free DX7 Virtual Synthesizer

Dexed Free DX7 Virtual Synthesizer

Dexed is a free multi-platform & multi-format plugin synth that is closely modeled on the Yamaha DX7. Under the hood, Dexed 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 à 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.

Dexed is licensed on the GPL v3.


  • Multi-platform (OS X, Windows, or Linux) and multi-format (VST, AU, LV2).
  • The sound engine music-synthesizer-for-android is closely modeled on the original DX7 characteristics.
  • 144 DAW automatable DX7 parameters available from one single panel.
  • Fully supports DX7 input and output Sysex messages; including controller change. This means that you can use this with a native DX7/TX7 as a patch editor and SysEx manager.
  • Each operator has a real-time VU meter to know which one is active.
  • Can load/save any DX7/TX7 SysEx programs. It is also possible to save a single program into a different SysEx file.
