there are detailed informations on this extension sound card on the topic pointed by Dal, and in addition you can listen to how it sounds:https://www.youtube.com/watch?v=2cYJGTL0QrE
At the time, when the B.A.T. game was released in 1989, on my Atari STF I hadn't heard anything so good from a computer (probably the Amiga could do something similar for digital music, but I hadn't access to one at that time). Some people said this extension card was a kind of bullshit and was only for protection (indeed it was also for the protection), but the sound was much better than what you could get on a normal STF (with no DMA). It was probably not rocket science (as you can see from the inside circuitry, it's quite simple), but it worked well. The music was also quite memorable. Some more music: https://www.youtube.com/watch?v=nxAHqYP9hAg
(I don't know what happened to this one, the sound is not very good)
And so they said several other games and applications should use this MV16 card in the future. I thought nothing came out, until I discovered of this Music Master, so I'm curious to try it for real or to hear some project using it. It's probably not better than what I could get from a modern soundtracker on PC or Amiga.
