Below (Below Threshold)
[Fixed Val, Source]
This sets the output of the Gate when the Control Source is less than the Threshold. When this is set to Fixed Val, you
can set a value between -100% and +100%. When it is set to Source, you can select any modulation source.
Above (At & Above Threshold)
[Fixed Val, Source]
This sets the output of the Gate when the Control Source is equal to or greater than the Threshold.
Offset
This adds a constant positive or negative offset to a modulation source, and also allows you to double the gain.
Input
[List of Modulation Sources]
This selects the input for the Mod Processor.
Level
[–200.00%…+200.00%]
+200% doubles the original signal level, while –200% doubles the level
and inverts the phase.
Offset
[–200.00%…+200.00%]
This controls how the Input is shifted up or down.
+200% shifts an input of –100 all the way to +100.
Converting from bipolar to unipolar
You can use Offset to convert a bipolar modulation source (both negative and positive), such as an LFO, to a unipolar
signal (positive only). To do so:
1. Select the LFO as the source.
2. Set the Input Amount to 50%.
This cuts the overall level of the LFO in half.
3. Set the Offset to 50%.
This shifts the LFO signal up, so that it now swings between 0 and +100.
Converting from unipolar to bipolar
Similarly, you can convert a unipolar modulation source to a bipolar signal:
1. Select the modulation source as desired.
2. Set the Input Amount to +200%.
This doubles the overall level of the modulation source.
3. Set the Offset to -100%.
This shifts the Modulation signal down, so that it ranges from -100 to +100.
