26: Doppler

26: Doppler

This effect simulates a “Doppler effect” (sound moving while changing its pitch) that sounds, for exam- ple, like an ambulance siren passing by. Mixing the effect sound with the dry sound will create a special chorus effect.

a: LFO Mode

The LFO Mode parameter switches LFO operation mode. When Loop is

a: Src

 

selected, the Doppler effect will be created repeatedly.

When LFO Mode is set to 1-Shot, the Doppler effect is created only once when the modulation source specified in the Src field is turned on. At this time if you do not set the Src parameter, the Doppler effect will not be created, and no effect sound will be output.

The effect is off when a value for the modulation source specified for the Src parameter is smaller than 64, and the effect is on when the value is 64 or higher. The Doppler effect is triggered when the value changes from 63 or smaller to 64 or higher.
