Chorus

The Chorus makes the deck sound wide and shimmering by blending it with a slightly delayed copy whose delay time wobbles slowly. It is the fifth unit in the effect rack. Its faceplate is the CH-2 Stereo Chorus, and its screen draws the modulation wave.

The left and right channels wobble a quarter of a cycle apart, which spreads the sound across the stereo field.

Control Range Default What it does
Rate 0.05 Hz to 5 Hz 0.6 Hz Speed of the wobble.
Depth 0 to 100% 50% How far the delay time swings, and so how strong the pitch wobble is.
Delay 5 ms to 30 ms 12 ms Base delay of the copy. Short delays sound tighter; longer ones sound more like a second voice.
Mix 0 to 100% 50% Balance between the dry deck and the delayed copy.

At the default Mix of 50% you hear the dry deck and the copy equally, which gives the classic chorus sound. Unlike the Flanger, Phaser and Auto-Pan, the Chorus has no tempo sync: it always runs at its Rate.

The strip’s readout shows the Rate.

  • Widen a mono sample. Most scratch samples are mono. A gentle chorus (low Rate, moderate Depth) spreads them out so they don’t sit as a single point in the middle of the mix.
  • Thicken pads and tones. On sustained sounds, a longer Delay with more Depth gives a lush, doubled sound.
  • Seasick. A fast Rate with high Depth gives an obvious vibrato-like wobble, which can be fun on long, slow scratches.
