Presumably you want to know how/what to do on a "specific" sound
module or drum machine you intend to use.
Some drum machines let you choose how
you assign sounds to incoming MIDI note numbers. So for example, 38 could by default
trigger your snare, but you could remap a different sound to be triggered by note 38.
It all depends on the features your specific device has. Check their manual.
If they can't do this, then you'll need something in between, like a
computer+software, to remap MIDI notes. This is usually a trivial thing for applications
like Logic, for instance.
