Chorus / Delay - E-Mu ProteusX Operation Manual

Chorus / Delay

This effect is a combination Chorus and Delay because the signal can be delayed up to a
full second (1000ms). Slightly modulating the delay time in the 15-20ms range
produces the familiar chorus effect.
When a longer delay is modulated, a kind of gliding pitch shift effect is produced.
Vibrato effects can be easily created by adjusting the modulation rate and modulation
depth parameters. When feedback is introduced to a long modulated delay, the sound
tends to get scrambled up in unpredictable ways which might be just the thing to create
that "swarming bees" effect you've been looking for.
Setting the feedback percentage in the negative range, inverts the feedback signal.
Negative feedback has the effect of deepening the cancellation notches which are
created when using short delays with feedback.

Parameter Description
Initial Delay Sets the length of the delay line. Range: 10ms to 1000ms.
Modulation Sets how much the LFO affects the delay time. Increases the amount
Depth of chorus effect and pitch shift animation. Range: 0% to 100%
Modulation Sets the frequency of the low frequency oscillator.
Rate Range: .01Hz to 15Hz
Feedback Sets the polarity and amount of delayed signal that will be recirculated
through the delay line. Range: -99% to +99%
Pan This parameter moves the delayed sound left or right. This moves the
apparent sound source left or right. Range: -99% to +99%
LFO -> Pan Sets the amount of panning that will occur at the Modulation Rate
Range: -99% to +99%
