Dexed – A free Soft-Synth emulating the Yamaha DX7

Dexed for Mac, PC and Linux

The free plug-in Dexed emulates the Yamaha DX7, a classic synth of the 80s. Like its role model Dexed uses a sound engine which is based on FM synthesis. Frequency modulation is a complicated topic and to get a decent sound originally you had to programm lots of parameters.

It took quite some time until other manufacturers like Native Instruments or Clavia came up with FM synthesisers which were easier to handle. Also Pascal Gauthier did a real good job with his freeware. The current version 0.9 of Dexed was released at the end of september 2016.




  • 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 realtime 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.
