Dexed is a multi platform, multi format plugin synth that is closely modeled on the Yamaha DX7. Dexed is also a midi cartridge librarian/manager for the DX7.

Not a Mac user but just mentioning that Dexed is a plugin that basically just loads.syx patches, and if you can't get it to work I'm pretty shure there are several other vst's that does the same job. Digital Suburban has released DEXED, a free FM Synthesizer VSTi Plugin inpsired by Yamaha DX7 available for Windows, Mac and Linux. Free Download: Dexed VST, AU plugin.

Minimal documentation is available on Dexed Wiki.

Examples from One Synth Challenge:

Dexed is free software and is licensed on the GPL v3.

Features

• 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 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.

Cartridge Manager

Desktop destroyer mac. Any .syx file in the Cartridges directory will be available from the 'CART' window. Find this directory by using the 'CART' button and then the 'SHOW DIR' button.

You can drag and drop any DX7 program from what is loaded in dexed and/or what you have loaded in the cartridge browser.

Double-clicking on a program will load the currently selected program in the plugin.

Use the context (right-click) menu to send the program/cartridge the DX7 or open your OS file browser from the directory context.

Hint: BlackWinny from kvraudio did a great DX7 compilation named Dexed_cart_1.0.zip. Simply unzip the content of this zipfile to your Cartridges directory.

Engine Type

Dexed can be configured to use some of the original math limitation of a DX synthesizer. This does notonly apply to the DAC, it also involves the bit resolution of the sine waves and the way that the amplitude is applied to each operator. Since all of this is experimental, multiple engines will be available to be able to compare them easily.

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.

Dexed is a free instrument plug-in for Windows and Mac.

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.

Dexed Fm Synth

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.
