There are purists out there who think computers ruined electronic music, made it cold and alien, removed the human element: the warm, warbling sounds of analog oscillators, the unpredictability of analog drum machines, synthesizers that go out of tune and have minds of their own. Musicians played those instruments, plugged and patched them together, tried their best to control them. They did not program them.
Then came digital samplers, MIDI, DAWs (digital audio workstations), pitch correction, time correction... every note, every arpeggio, every drum fill could be mapped in advance, executed perfectly, endlessly editable forever, and entirely played by machines.
All of this may have been true for a short period of time, when producers became so enamored of digital technology that it became a substitute for the old ways. But analog has come back in force, with both technologies now existing harmoniously in most electronic music, often within the same piece of gear.
Digital electronic music has virtues all its own, and the dizzying range of effects achievable with virtual components, when used judiciously, can lead to sublime results. But when it comes to another argument about the impact of computers on music made by humans, this conclusion isn't so easy to draw. Rock and roll has always been powered by human error-indeed would never have existed without it. How can it be improved by digital tools designed to correct errors?
