I found some karaoke devices "MIDI音源BOX" use Roland chips on random Chinese website.

It seems a SC-8820 inside there . The seller said it was very new and there were 8 of them in total. The price is 150 Chinese yuan each.

It looks like someone took some Roland/Edirol hardware boards out of eRecycling and coupled them with a new I/O board to make a new MIDI module. I wouldn't be surprised if it works relatively well, at least for a time.
