A modern sampled snare in a drum library will comprise thousands of multi‑velocity recordings.

Sample sizes are now only limited by the amount of hard disk space available - and hard disk space is cheap - so sample‑library developers can and do concentrate on recording everything, including the kitchen sink (quite literally: FXpansion's BFD Percussion expansion pack contains multisamples of a kitchen sink!).

There's practically no limit to the size of a sample library any more, because most software samplers stream their data directly from disk. Sample libraries have progressed in leaps and bounds since the days when Akais and Emus ruled the studio. The difference is that this time, when you close your eyes it sounds like the real thing. Just like many drum machines, these libraries provide you with both the sounds and the sequencer needed to create drum patterns. We may not call them drum machines any more, but modern drum libraries such as FXpansion's BFD2, Toontrack's Superior Drummer 2, Steven Slate Drums, and XLN Audio's Addictive Drums have inherited a great deal from the humble drum machine. They had a charm of their own, of course, and they still do - but nobody would close their eyes and mistake the sound for that of a real drummer.

Nobody in their right mind would tell you that those machines sounded realistic, even though, in most cases at least, that was their main goal. Travel back a quarter of a century, to the year in which the first copy of SOS hit the shelves: this was the golden age of the drum machine. Today's multi‑gigabyte drum libraries include some fantastic sounds and groove presets - but they haven't taken all of the work out of creating a great drum part.
