I've found an iOS/iPadOS app called
BarbaXDrums. It's a pretty decent sounding drum module and after some tweaking very usable with MegaDrum. It features a number of kits.
It doesn't support all features, like for instance only open or closed hihat. Nothing in-between. Choking is supported if setting the MD to choke on alt note, but only for ride and crash. Not on hihat. Crash only supports one zone (but there are multiple crashes) but ride supports three. Four toms are supported but only one zone each.
So, all in all, a good app. Snatch it while on sale, which happens quite frequently. Or pay full price, which is pretty good for what it is anyway.
