7. If you set the Rate to zero you will hear a fixed effect due to the non modulated Delay A good preset to illustrate this is Queenguitar Finally you can link the Rate parameter to the Depth parameter using the Link button This keeps the MetaFlanger effect relatively the same flavor at any rate setting by keeping the actual pitch shift the same Depth Default setting 1 0 The Depth control sets how widely the wet signal is shifted in time which results in small pitch changes This controls how powerful the effect is The center of the changing time delay is set using the Delay con trol In other words if Depth is 0 the delay is fixed at the value shown When Depth 50 the delay time will vary by half of its value The default Depth setting is 100 so the Delay time 2 2ms will vary between 0 0 and 4 4ms Notice the green indicator oscillating back and forth in the Modulation display this display is located under the Waveform control If you set the Depth to 1 0 the green indicator will travel right from one end of the display to the other at a speed determined by the Rate setting and you ll hear your audio swoosh accordingly If you set the Depth to 0 1 you ll see the same green indicator move from side to side barely changing its horizontal displacement at all and you ll hear a much smaller flange effect Zero Depth means no flanging Rate and Depth Link Default setting unlinked Cl
