Drum Sampler for AfterTouch

[raintalk]

I have AfterTouch for iPhone7
https://itunes.apple.com/us/app/afterto ... 01231?mt=8

I'm looking for a good drum sampler to drive with AfterTouch
Something with multisamples, and pressure (aftertouch)
Like timps that mute, or crashes that choke

I have SampleTank. It sounds good, but what a battery hog.
What are some good drum samplers that can take MIDI for IOS?

Thanks!
