About Dexed

Dexed is a multi-platform, multi-format FM plugin synthesizer closely modeled on the Yamaha DX7. It also works as a MIDI cartridge librarian and manager for DX7 patch files. The homepage lists Mac OS X, Windows and Linux, and lists VST, AU and LV2 as plugin formats. The homepage also describes Dexed as free software licensed under GPL v3.

The plugin puts 144 DAW-automatable DX7 parameters on one panel and shows a real-time VU meter for each operator. It supports DX7 and TX7 SysEx input and output, so it can be used with a native DX7 or TX7 as a patch editor and SysEx manager. Users can load and save DX7 and TX7 SysEx programs. Dexed offers three engine types: Modern, Mark I and an experimental OPL Series engine. The homepage says the engines can be compared, but the OPL Series envelopes still need tuning. Documentation is minimal and is kept on the Dexed Wiki.

Dexed FAQ

Can Dexed be used with a real DX7 or TX7?
The homepage says Dexed fully supports DX7 input and output SysEx messages. It can be used with a native DX7 or TX7 as a patch editor and SysEx manager.
How do I load a cartridge collection into the cartridge manager?
Unzip the files into the Cartridges directory. To find that directory, use the CART button, then the SHOW DIR button. Any .syx file in the directory then appears in the CART window.
