Ringway TD-82 Electronic Drum กลองชุดไฟฟ้า TD82/92 is a MIDI device, a controller and it has built in sounds. Just like newer MIDI devices, its uses USB printer cable unlike the old standard MIDI cable. Its not a synth, meaning the built in sound cannot be tweaked/edited and its also not a sampler that is why lots of members connect it to the PC to replace the built in sounds using software samplers. *from Facebook: TD82/92 Electronic Drums Usergroup
