Trigger Source
Trigger Source (Parameter mode, Page 4) determines what will trigger the Panning
effect. This can be set to: Audio Left, Audio Right, Audio L & R, Advance
Footswitch or Bypass Footswitch.
¥ When set to AUDIO LEFT, AUDIO RIGHT or AUDIO L & R, the Panning effect
will be triggered whenever an audio level greater than -12 dB is sensed at the
selected input(s).
¥ When set to either ADVANCE FOOTSWITCH or BYPASS FOOTSWITCH,
the selected footswitch will not perform its normal function (that of advancing
to the next Program or bypassing effects, respectively). Instead, the Panning
effect will be triggered when the selected footswitch is pressed.
Phase Inverter
The Phase Inverter effect serves only one function: it shifts the phase of the audio
being fed into its input by 180°. Phase inverting has many useful applications, one of
which is used to record additional tracks on a multi-track recorder in order to
simulate a surround effect. The Phase Inverter has only one parameter: Output
Phase. When the Output Phase is set to INVERTED, the phase of the audio is
shifted 180°. When set to NON-INVERTED, the audio is left unchanged.
This can be useful for a varity of sound design applications. Try creating your own
feedback loop in a delay (by making a route which feeds back into the delayÕs
input) and inserting this phase inverter. Or try flipping the signal out of phase
before sending it through a chorus or flange for a thinner sound. The Phase Inverter
can also be useful in video post production as a quick and dirty surround panner.
