Slope Overload

Slope Overload

Slope Overload is a special kind of bitcrusher. It uses 1bit Delta Modulation encoding to emulate the sampler channel of a certain Entertainment System from the mid 80s.

The same DM encoding is used in the sampler modules of BitRate II and MonoBoy.

A filter and noise gate have been added to help control the output.

SOOG V2 Screenshot


SOOG V2 (Sub Octave Oscillator Generator) is an analogue style octaver effect for monophonic signals.

The effect produces a fuzzy version of the input signal, by generating a modulated square wave one octave below the tracked pitch. This fuzzy octave can then be filtered to smooth out the tone, or to create synth style sounds.
