The Dual Chorus creates two different pitch “voices”, while the Octal Chorus creates eight voices for extremely full, rich sounds.

Figure 4-1 Modulation Example

The only difference between choruses and flangers is that flangers use less delay and have a feedback Parameter that sends a portion

of the effected signal back to the input of the Module. When the effected signal reaches the input, it is sent through the Module

again, building thickness and depth. If you increase the feedback enough, the source begins to lose its own original pitch to the

dramatic pitch modulation of the feedback loop.

LFO Waveforms: There are four LFO waveforms available for Choruses, Flangers, Phasers, Tremolos, Auto Panners, and five for Modifier LFOs.

They include SINe, TRIangle, SPecial-1, SPecial-2. See figure 4-2 for examples of what these waveforms look like.

Chorus

Chorus is probably the most basic modulation effect. It is really just a very small delay whose time is always changing. As the time is varied, the

delayed signals' pitch changes (just like a tape recordings' pitch raises when you play it faster). By moving the time back and forth, you hear a

sound that goes in and out of tune. When combined with the original sound, it almost sounds like more than one instrument is playing. The

2120 VGS uses several choruses at once to make huge rich sounds. For example, the octal chorus uses eight chorus voices at once to create an

incredible ensemble of sound. Aside from the more obvious speed and depth parameters (which adjust respectively how fast and far the sound

goes out of tune), the 2120 VGS allows you to use different waveforms. The waveform defines how it will move in and out of tune. The triangle
