Rez Filter Seq
Key Tracking
Resonance
0-100. Resonance emphasizes the frequencies around the cutoff frequency. At 0,
there is no emphasis, and frequencies beyond the cutoff will simply diminish
smoothly. At very high settings, the resonance can be heard as a separate, whistling
pitch. At medium settings, the resonance will alter the timbre of the filter, but will
not usually be heard as a separate pitch. The timbre and intensity of the resonance
will change depending on the filter Type setting - 4 Pole, 2 Pole, or 2 Pole > 2 Pole.
Seq Mod Amt
+/-100. This sets the amount of resonance modulation from the sequencer.
Envelope
0-100. The ADSR envelope can be used to control the filter cutoff frequency, adding
to the setting on the Cutoff knob. When Envelope is set to 0, the envelope will have
no effect. At +100, the envelope will open the filter all the way at its peak, even if
Cutoff is set to 0.
