AIR Filter Gate (RTAS)
You can use the Filter Gate effect to chop up the audio signal into staccato rhythmic patterns with
variable filtering, amplitude, and panning.
The following table lists the AIR Filter Gate plug-in parameters:
Parameter Description
Pattern Lets you select from a number of preset rhythmic patterns that the gate will follow.
Gate • Attack — Lets you adjust the duration of the attack as a percentage of the step duration.
• Hold — Lets you adjust the duration of the hold (or sustain) as a percentage of the step
duration.
• Release — Lets you adjust the duration of the release as a percentage of the step duration.
Filter Provides controls for the selected filter type:
• Mode — Lets you select the type of Filter:
- Off (no filtering)
- LP (Low Pass filter)
- BP (Band Pass filter)
- HP (High Pass filter)
- Phaser (Phaser)
• Cutoff — Lets you adjust the Filter Cutoff frequency.
• Res — Lets you adjust the Resonance at the Cutoff frequency.
Modulation • Env — Lets you adjust how much an envelope follower affects the Cutoff frequency. Note
that the Cutoff is fixed for the duration of each step, so it will not respond to a peak in the
envelope until the start of the next step.
• LFO — Lets you adjust the amount of LFO modulation of the Cutoff frequency.
• LFO Steps — Sets the duration of one cycle of the LFO to the selected number of steps.
Changes to the Step Rate consequently affect the durations of cycles of the LFO. When set
to Random mode, the level of the LFO changes randomly every step, for a “sample and
hold” waveform.
Rate Lets you select the duration, or frequency of the Low Frequency Oscillator (LFO). The duration
of one cycle of the LFO is measured in Steps.
Mix Lets you balance the amount of dry signal with the amount of wet (filtered) signal. At 50%, the
output includes equal amounts of dry and wet signal. At 0%, the output is all dry and at 100% it
is all wet.
