LinPlug Octopus - Manual (Page 39)

Master
The Octopus' Master module is located on the lower right of the
instrument's front panel. The Master module contains three controls: Gain,
Distortion and LoFi Waves. These are described below.
Gain
The Gain control is a final scaling factor that can be used to either boost or
cut the overall output of the instrument.
Distort
The Octopus features a tube-like distortion effect that can be used for
adding warmth to sounds. The effect is controlled using the Distort
(Distortion) control. Turning the control in a clockwise direction adds more
distortion to the signal.
LoFi Waves
The LoFi Waves control is used to set the accuracy of the Octopus' signal
generation. When the LoFi Waves control is switched on the following
effects occur: lower quality waveforms are used for signal generation,
waveform interpolation is less accurate and waveforms are stored in less
memory. This is useful if you're trying to replicate the sounds of an early FM
synthesizer.
