RA: Understanding groove

If you play the piano, violin or trumpet, to name a few, the rudiments of learning to play your instrument well include being able to play in tune and in time. As producers of electronic music, we don't have those concerns---we can input notes in step-time, or slow the click track down to record notes at a speed we can handle. We can then fix the pitch or timing of any notes we played incorrectly, giving us a safety net that acoustic musicians don't have. In fact, when it comes to playing in time, our workstations can help us achieve the impossible perfect timing. Using quantization, we can snap every note within our sequences to a precise location to produce a flawless rhythmic foundation.
