get/set sample are 'drawing primitives' that are the equivalent of
get/setting a single pixel in images. Yes, you can draw anything a
pixel at a time, but it's mighty tedious. You might want to lay down
a tone, or some noise, or shape the sound with an envelope, or do a
whole host of other operations at a higher level than
sample-by-sample, just as canvas supports drawing lines, shapes, and
so on. That's all I meant by the reference to MIDI.
