Tremolo/Auto Panner
Tremolos and auto panners are similar to one another because they use an LFO to modulate the level of the signal. This allows you to recreate the tremolo effects commonly found on vintage instrument amplifiers. Auto panners can be quite useful in a studio environment because it means that the panning does not have to be achieved manually. However, it would have to be set quite accurately in order to stay within the beats per minute (bpm)
Parameters
Speed - This controls the oscillation of the effect.
Hold Time - As the name suggests, this adjust the amount of time the effect hold the time at the required point in the stereo/surround field
Depth - This adjusts the intensity of the effect. As depth increases, the effect becomes more dramatic.
Center/Surround - This controls the positioning of the effect in the stereo/surround field.
