DESCRIPTION:
Playing MS20 mini with MT-50, MT-50 is playing recorded drone sounds of MS20 mini.

I found this Yamaha MT-50 at a secondhand shop, it was sold as a "Junk" but cosmetically looks fine for the 20 years old stuff.
Then I bought it and checked, it is "Junk" as they said but it is alive, still in working condition :D
