Rez Filter+Amp
2 Pole. This is a 12dB per octave filter. Compared to the 4 Pole, this offers
significantly less attenuation of frequencies beyond the cutoff, but with slightly
more pronounced resonance.
2 Pole > 2 Pole. This is two 12dB per octave filters in series. Of the three types, this
offers by far the most extreme resonance effect. Compared with the 4 Pole, it has
just a little less attenuation of frequencies beyond the cutoff.
LFO Mod
Frequency
0.00-100.00Hz. This sets the frequency of the LFO,
Waveform
LFO Sine, LFO Triangle, LFO Saw, LFO Square. This selects the shape of the LFO.
Filter Cutoff
On, Off. This enables and disables modulation of filter cutoff by the LFO.
Resonance
On, Off. This enables and disables modulation of filter resonance by the LFO.
Depth
0-100. This sets the depth of the LFO modulation.
Mod Source
List of Modulation Sources. This sets the modulation source for controlling the
LFO depth. For a complete list, please see "Modulation Sources" on page 2.
Mod Amount
+/-100. This sets the amount by which the mod source affects the LFO depth.
Amplifier
These parameters control an ADSR envelope dedicated to the output volume. For a
graphic explaining ADSR envelopes, see the figure "ADSR Envelope," above.
Attack
0-100. This sets the attack time of the amplitude envelope, which controls how long
it takes from the moment that the key is pressed until the envelope reaches its peak.
Decay
0-100. This sets the decay time of the amplitude envelope, which controls how long
it takes the envelope to fall to the sustain level after the attack is complete.
