4.6.1. Shared features
Both PolyBrute filter modules have the following controls:
•
Cutoff
sets the corner frequency individually for each filter.
•
Resonance
emphasizes the corner frequency. Higher resonance levels can cause
a filter to self-oscillate.
•
VCF Env Amt
controls the level of cutoff frequency modulation caused by the
VCF ENV. It's a bipolar control, so positive and negative envelopes are possible.
•
Level
adjusts the output of the filter.
4.6.1.1. Master Cutoff
Both filters are affected by the
Master Cutoff
knob, which sweeps the cutoff frequencies of
both VCFs at the same time. To reset the Master Cutoff value to 0, hold the Preset left arrow
and turn the Master Cutoff knob.
4.6.1.2. Key Track
This determines how much the cutoff frequencies of both filters change based on the key
that is played. Values range from no change (100% left) to maximum change (100% right),
in which the cutoff frequency increases or decreases relative to the distance of a note from
middle E (MiDI note 64). The filters are gradually opened above that note and gradually
closed below that note.
