Dexed: DX7 FM multi plaform/multi format plugin

Please see Dexed User Website for user and download information.

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 and JUCE as an application/plugin wrapper.

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. The msfa component (acronym for music synthesizer for android, see msfa in the source folder) stays on the Apache 2.0 license to be able to collaborate between projects.

Pre-release builds are available with the Nightly Releases

Donations have been discontinued (thanks to everyone who has contributed!). I'm planning to release a new Farfisa Organ synth for iOS — that will be the way to support Dexed going forward.

Changelog

Version 1.1.0

Complete rewrite of event handling to support a modern plugin framework

This should solve most of the pending automation issues Dexed had with other DAWs

Dexed should be much more responsive now that events are handled entirely by JUCE

Note that a Dexed 1.1.x DAW project can read 1.0.x ones, but not the other way around

Cleanup of most remaining usages of deprecated code

Source tree reorganized (Source/ -> source/, Documentation/ -> doc/) into core/, engine/, midi/, parameter/, ui/ modules; the bundled VST3 SDK submodule was removed in favor of the one pulled in via libs/vst3sdk/CLAP

Fixed filter click on automation

Fixed possible crash on malformed cartridge data

New developer view that lets advanced users inspect Dexed's internal state — ALT+CLICK on the Dexed logo opens the debugger. This is for internal use only and unsupported.

Version 1.0.1

Let DAW scale the UI and then let the user zoom it further if needed

Fixed scaling issue with CLAP format

Plugin parameters dialogs are now part of the main plugin window (no more separate windows)

Version 0.9.9

Partial portamento implementation. Thanks @jpcima

More accurate LFO implementation. Thanks @mtarenskeen

Fix UI scaling resize bug

Avoid clicks on voice allocation issue. Thanks @akwizgran

Respect MIDI channel on control change mappings. Thanks @voidshine

Mouse wheel movement is now more precise with shift down

Dexed now replies to sysex "Patch Request" messages

Active program is now easier to see

Version 0.9.8

Accessibility implementation (including keyboard shortcuts)

UI component refresh

Mono/Poly parameter is now a plugin parameter

Copy/paste operator values are now text based (and system wide)

Fix Apple Logic startup issue

Version 0.9.7

MTS-ESP microtuning support

CLAP plugin support (sadly scaling is not available for now, but we are working on this)

Scalable UI upgrade (better resolution), optimized UI redraw

More accurate VU meter. Thanks @FulopNandor

Releases are now notarized for macOS

Fix for VST3 automation (again)

For developers: cmake is now the built system

How to build

Clone Dexed from github

~ $ git clone https://github.com/asb2m10/dexed.git

Dexed has several submodules it now depends on, including VST3/CLAP and a library to support non standard tuning. After you clone your first step is

~ $ cd dexed ~/dexed $ git submodule update --init --recursive

Then you crate the cmake build files that are will be created in the build directory. On that build you can trigger your favorite IDE or simply use --build cmake option.

~/dexed $ mkdir build ~/dexed $ cd build ~/dexed/build $ cmake .. -DJUCE_COPY_PLUGIN_AFTER_BUILD=TRUE ~/dexed/build $ cmake --build .

If you get missing header compilation errors, be sure to check the known Linux dependencies based on your distribution for Linux.

Binaries will be found in ~/dexed/build/source/Dexed_artefacts/*
