A few simple questions about inputs

Hi everybody, i'm new here
A few simple questions about inputs :
Do 1 Stereo input = 2 Mono inputs ?
Are Mono inputs sensitive to piezo velocity ?
About MIDI :
If 1 Stereo MIDI channel = Left and Right.
Is it possible to assign Left->Snare, and Right->Kick ? (for exemple)
Precision, i'd like to build a Megazen (~Zendrum) instrument.
It's why i don't need dual zone sensitives pads (stereo), but mono inputs by hitting bottles tops.
