S-MU2000

An open source Yamaha MU2000 emulator. It runs the MU2000's own firmware, dumped from your unit, as a desktop player with a hardware-style panel, as a VST3 / CLAP / Audio Unit plug-in — or try it right here in your browser below.

Web Demo

The MU2000 tone generator in your browser, emulated from its own firmware and ROMs. Offline render runs the full emulation; live playback starts in a lighter mode (Fast synth) so it keeps up on ordinary PCs. Fully open source.
