8.4.4.3. Chorus
A Chorus delays the signal, then uses an internal low-frequency oscillator (LFO) to vary the
playback speed of the delay, throwing the delayed signal out-of-tune with the input, like
vocal doubling. The amount of change in pitch depends both on the depth of the delay range
being scanned, and the speed and waveform of the modulating LFO. The effect is similar to
a flanger, except that since the delay time of a chorus is longer than that of a flanger, the
delayed signal is out-of-tune instead of comb filtering. This results in a more-subtle but still
very useful effect.

♪: The Chorus effect is similar in results to the Unison detune [p.19] feature of the JUP-8 V4, but it
doesn't consume polyphony.
Control Description
Voices
Selects the number of delay lines the chorus will use (from 1 to 3), with a different starting phase
for each voice.
Delay Sets the amount of delay applied to the input signal, from 0.6 to 20 milliseconds.
Depth
Controls the depth of the chorus (e.g., how far above and below the incoming pitch) by adjusting
the range of time that will be scanned, from 0 to 10 milliseconds.
LFO
Shape
Toggles modulation LFO between sine and triangle waveforms.
Frequency Adjusts the speed of the chorus (the frequency of the scanning LFO) from 0.1 to 5 Hz.
Feedback
Controls how much of the output is fed back into the input, creating more harmonics. Appears
as a Mod Destination in the Modulations section and Mod Sequencer.
Stereo Switches between mono and stereo output.
Dry/Wet
Controls the balance between the input signal and the effected signal. Note: Chorusing is most
effective when there is a mixture of wet and dry signal, so there are beat frequencies between
them.

♪: There is a crucial relationship between Depth and Frequency. If Depth is high but Frequency is
low, the effect is of a subtle de-tuning. As Frequency is increased, the result is more like a vibrato where
the LFO frequency is obvious.
