About Dexed
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 as its synth engine and JUCE as the application and plugin wrapper.
The goal is to be a tool and companion for the original DX7, so the project stays compatible with the original machine rather than adding features beyond it. Musicians and sound designers can use it to play and shape classic FM sounds, including from inside a digital audio workstation.
Highlights
- Closely modeled on the Yamaha DX7 and kept compatible with the original machine
- Multiple plugin formats, including VST3 and CLAP
- MTS-ESP microtuning support
- Responds to sysex Patch Request messages and respects MIDI channels on control change mappings
- Scalable interface with accessibility support, including keyboard shortcuts
