Boots the synth in an AudioWorklet and plays it from WebMIDI inputs (up to 4 ports, A–D) in realtime. You need ROMs extracted from your own MU2000 (see Preparing the ROMs); they are stored locally in your browser and never uploaded anywhere. Works best in the Firefox browser.
Picked ROMs are stored locally in this browser.
Not perfectly accurate, but true emulation requires a very powerful PC. Takes effect when the synth boots and locks afterwards.
