FX21-Ring Modulator

Figure 88 : The ring modulator effect is applied to the highlighted section of the wave file.

Ring modulators have never really gained wide acceptance in the musical community, probably because they create tones that are mathematical in nature, not harmonic or musical. They can be used to create bell or gong type sounds, and are occasionally used on drums and percussion.

Figure 89 : Control settings for the ring modulator effect.

Ring Modulators accept two different input signals, The original, unaltered, input signal, and an on board oscillator (usually square or sine wave) with a range of approximately 1hz to 5.5khz (this plugin anyway). They create two frequencies : the sum of these two signals and the difference between these two signals.

For example, a guitar playing an A note (440hz) and the oscillator set on 220 hz (also an A note). The output signal would be the sum of the two notes (660hz), and the difference between the two notes (220hz).
