The sampling for drums in the new Connect app will make it possible to make drum presets including such things. It was possible to do that previously actually but only by modifying presets which Artiphon, quite properly, wouldn't support.
Artiphon also hints at the other creative possibilities that capability allows, which has a lot of potential.
(Mind you, I haven't actually tried it out!)
I suppose they may add this to the Preset Creator app as well which would allow pre-recorded samples to be used.
