Dexed vs VCV Rack

Dexed is a free synth plugin and standalone app modeled on the Yamaha DX7. It runs on Linux, macOS and Windows, with VST, AU and LV2 plugin formats. Its sound engine follows the original DX7’s characteristics and includes Modern, Mark I and OPL Series engine types. Dexed also serves as a MIDI cartridge librarian for the DX7: it can load and save DX7/TX7 SysEx programs, save an individual program to a separate SysEx file, and exchange DX7 SysEx messages, including controller change. A single panel exposes 144 DAW-automatable DX7 parameters, and each operator has a real-time VU meter. Microtuning and MPE support were contributed by the Surge Synthesizer Team. Dexed is free software under GPL v3, at free. The project says documentation is minimal and cautions against expecting a perfect DX7 clone. Release 1.0.1 fixes scaling issues and rebuilds the Linux binary for older glibc versions.

VCV Rack is a virtual modular platform modeled on Eurorack synthesizers, available as a standalone app for Linux, macOS, and Windows. It supports learning, live performance, algorithmic and generative composition, and multitrack recording. Its ecosystem includes 30+ built-in modules, 170+ official modules, and 2000+ modules in the VCV Library. For hardware connections, it offers audio or CV input and output across multiple interfaces, plus polyphonic MIDI input and output. Rack Pro adds VST2, VST3, Audio Unit, and CLAP support, with integration tested against listed DAWs including Ableton Live, Cubase, Reaper, Logic Pro, and others. It can render audio offline through a DAW and supports up to 16 audio input/output channels, MIDI, and parameter automation. Rack Free is open-source with community support; Pro includes professional support and costs $149, paid once. VCV Host can load VST plugins into Rack and control their parameters with CV, but is purchased separately. Rack requires 1 GB memory and disk space; dedicated Nvidia or AMD graphics are recommended.
