Happy Nerding FM AID is a through-zero linear FM module that can use any signal as a carrier and modulator.Standard for digital FMPhase modulationComplete methodAnalog circuitImplemented in and provides FM without aliasing.FM in the original analog domain modulates the frequency of sound sources such as oscillators, but phase modulation has the advantage of being able to modulate any sound source that cannot be frequency-modulated.As a sound character, phase modulation produces a brighter sound than conventional FM.
HOW TO USE
Phase modulation typically considers the descending saw waveform as the base for the carrier input.This is also reproduced in FM AID, and in order to actually obtain the output waveform from each jack of sine wave, triangle wave, sawtooth wave, and square wave, input the descending sawtooth wave to the carrier input.In that case, for example, the FM pulse waveform is output from the pulse waveform output.However, in reality, any audio can be input to FM Aid, so let's input various audio other than the descending sawtooth wave to the carrier.
The index, which means the strength of the modulation, is controlled by the FM knob, and the strength of the modulator can be controlled by the CV, and is attenuated by the CV knob.Feedback FM that returns the output to the modulator input is also possible.
The carrier and modulator inputs are internally wired, and patches to the modulator inputs block internal routing.This is a convenient optional feature for using a single signal as a carrier and modulator at the same time, which eliminates the frequency difference between the carrier and the modulator, but allows you to obtain a variety of interesting wave folding sounds.
