Join J. Scott Giaquinta for an in-depth discussion in this video Transposing tracks: Pros and cons, part of Ableton Live: DJing.
- Sometimes when you're trying to mix harmonically, you…find songs that work vibe wise, but are a key or two off.…So this is when transposing or…pitch-shifting a track can come in handy.…But here's the problem.…Because of the nature of time compression…and expansion this could introduce glitches…and anomalies into your audio if you're making…dramatic pitch or temp changes.…First lemme explain how pitch relates to tempo.…Let's say we aren't using Ableton and we're just using…a CD or turntable and we only have pitch adjustment.…Let's say we're playing a track in…the key of C at exactly 128 beats per minute.…
If we wanted to hear this track in the key of B instead,…which is one semitone below C, we'd have to…slow the song down by a percentage that is…equal to a pitch-shift of one semitone.…That value's been determined to be 5.455% exactly.…So let's do some math.…128 times 0.05455…equals 6.9824.…Then 128 minus 6.9824…equals 121.0176.…
That means in order to hear this track in the key of B…we'd have to slow it down 5.455%…
Scott next introduces some performance tricks to wow your audience, by integrating loops, samples, and FX. He also provides a demo of alternative controllers that can make your performances more dynamic, including a Wiimote, joystick, MIDI keyboard, and live vocoder. Finally, he discusses methods to record your live DJ set and fine-tune it after the fact.
