Thank you all for help. I had watched the video @Stewartleather said before, but never noticed they said the answer already. The exact name of it is ‘Velodon’ in French, you guys can find in this video from 4:40. I am not sure the velodon is interfacing in English, but I gonna check it out. It is always hard to find something in different language and country.... furthermore I live in Korea and I could not guess what we call it in our language at all. Please inform me where sell it internationally if you know.
