QUARTET CHORUS ENSEMBLE504
Mod Depth
This determines the depth of the LFO modulation, i.e. by how much the delay time should be modulated. If you set this
to 0, the delay time will be static (unless you are using Noise Mod, see “Noise Mod”).
! If Mod Depth and Noise Mod (see “Noise Mod”) are both set to 0, the Width control (see “Width”) has no ef-
fect.
Mod Rate
This determines the frequency of the LFO modulating the delay time.
Range: 0.20-10.00 Hz
Noise Mod
This amplitude-modulates the signal with lowpass filtered noise, and generates a kind of “sparkling” effect.
! If Noise Mod and Mod Depth (see “Mod Depth”) are both set to 0, the Width control (see “Width”) has no ef-
fect.
FFT
The FFT algorithm simulates a type of chorus/ensemble effect by utilizing noise modulation of the signal partials.
First the signal is analyzed using FFT (Fast Fourier Transform) and converted to a representation in the frequency
domain. Then, the partials are modulated by noise to achieve a very nice and dense ensemble effect.
FFT Size
This sets the accuracy (and speed) of the frequency analysis. “1” is the fastest detection and preserves transients in
the signal - but this also leaves out detection of low frequencies. “4” is the most accurate detection. However, it’s also
slower since it also detects low-frequency material (which takes a little longer to detect).
