Generators are conveniently packaged test oscillators, meant for use in designing modules.

f = Frequency (Hz)
A = Amplitude

The Frequency knob works from 0-1.  Press a multiplier button to adjust the frequency range.  The maximum frequency is 10,000Hz.

The Amplitude knob works from 0-1.

This module outputs an Alternating Signal (AS), meaning its output swings between -1 and +1.
