Expert Sleepers Augustus Loop v2.4.1 - Manual (Page 27)

Shape
Controls the shape of the saturation. At '1.0' the effect is that of soft saturation and clip-
ping. At '0.0' the effect is of hard digital clipping. Note that at shape settings other than
'0.0', some alteration is applied to the signal even if the Saturation level is zero.
Tape Sim
The Tape Sim controls are displayed by clicking on the ‘Filter’ button at the top left of the
filter controls.
The audio processing controlled by this section is applied before the filter/saturation
processing described above.
Drive
Applies a fairly smooth saturation distortion kind of effect. The range of the control is
large, for extreme effects, but for a nice ‘tape-ish’ sounding effect, try settings in the lower
range, around 12db or so.
Crunch
Applies a quite extreme, non-linear, mangling to the audio. You will typically need to
wind the Drive control up a little if you apply any Crunch.
Gain
Applies a simple level boost to the audio. This is typically useful when you apply some
low and high cut (see below) to bring the level of the audio back up so you can still get
long-lasting delay echoes.
Lo Freq/Lo Amnt
Applies a low frequency cut to the audio, rolling off some of the bottom end.
Hi Freq/Hi Amnt
Applies a high frequency cut to the audio, rolling off some of the top end.
