Adje

an eratosthenean spectrum generator

The design of Adje (‘little Ad’) is based on Ad, but it’s not an oscillator and doesn’t produce an audio signal. Instead it generates (making use of VCV Rack’s polyphony feature) three polyphonic control voltages: pitch (V/octave) and amplitude (left and right). The intended use is to patch the V/octave output to an oscillator, the amplitude output to the CV input of a VCA, and the oscillator trough the VCA. (Both these modules should be able to work with polyphony.) The number of output channels can be set using the context menu.

For the rest, it works similar to Ad, though some knob ranges are different. Furthermore, Adje only takes monophonic input CVs, it doesn’t have an FM input and the buffer length is 4 seconds.

There is an expander module Bufke for Adje.
