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 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 v2.


  • Multi platform (OS X, Windows, Linux) and multi format (VST, could build a AU also); by using JUCE.
  • 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.
  • Each operator have 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.
  • Comes with a 1024 programs compilation.

Version 0.7.0:

  • Preliminary Algo 4 & 6 feedback support.
  • DX Engine 'Dirty DX' emulation, including one based on OPL chips.
  • DX Engine LFO amplitude. This still needs tuning.
  • Monophonic mode.
  • Added the 'INIT' button to re-initialize a program.
  • Fixed stucked notes when programs where changed.
  • Fixed engine envelopes wrong timing if it was not 44100kHz.
  • Fixed only .syx are shown when we are using the Dexed_cart.zip cartridges collection.
  • The DX7 Sysex port are now only used for sysex messages. This is used to avoid any MIDI note feedback.

This is actually a very interesting emulation. I haven't really been impressed by FM8 as _an emulation_ of DX7s etc, but I can respect it as a good synth in it's own right. From this I actually hear a very DX7 sounding synth. I think brass patches sound very cool for example, in a way that can't really be made with other synth types. Well done.

And man is the interface pretty.

Jk, it looks ass, but charming in its own way :)

Outstanding DX7 emulation ! A masterwork !
Features to add :
- A "panic" button that kills all sound output as some sounds seem to be buggy and loop forever.
- An "init" button to start sounds from scratch, like there was one on the original DX7.

The "init" button has been added in the 0.7.0 version.

The sound loop bug is fixed; so, no need for "panic" button.

tnkdesbois: I hear ya. I think the "loop" you might talk about is when you play a patch and change patch while holding a key, then the old patch never receives a note off and keeps going, if I'm not mistaken. But your problem might be different.

And you can actually flip back to the old patch and hit the hang up key to make it stop. But yea, a bit confusing :)
