Sadly it’s quite hard (and expensive!) to get a real SC-55 in the UK :/
The 8820 is the same architecture etc as the SC-55/88/88 Pro, so the simulation is basically swapping out the sample sets. I can’t tell the difference :)
I checked this and it doesn't seem to be working for me - I can select it as a GM synth in the settings and select the right MIDI port, but it's not actually playing out via WebMIDI - it sounds like it's still using ADLMidi. Same behaviour in both Firefox & Chrome.

My next target is a MT-32 :)
