Signal flow

This chapter describes the signal path through Devastor. It also explains the basic components of the effect unit and their control parameters.

Basic modules

Internally, Devastor consists of a few basic components. These correspond to the sections on the graphical interface.

Dynamic’s flattener

Depending on the value of

Dynamics

knob, this module will equalize levels in the signal’s amplitude. Its principle of working is similar to a

compressor’s operation with auto normalization of the amplitude. However, its control (using one knob) is much simpler than that.

Dynamics knob

Diode clipper

This is the central and the most important element of Devastor. It simulates the behavior of a diode clipper analogue circuit. The signal
