It doesn't take many notes to make something impossible in practice. On piano 11 notes simultaneously makes it impossible for one person to play and it would probably sound a lot more coherent. The black midi I've listened to doesn't sound bad, but it all sounds quite similar - there isn't much range.

You can probably get to 12 to 14 and still sound good by using some of the fingers to play multiple neighboring notes.
