CUT-OFF FREQUENCY (2)
- sets the cut-off frequency of the filter.
RESONANCE (3) REZ
- sets the resonance of the filter.
ENVELOPE SOURCE (4)
- determines whether the filter cut-off is modulated by envelope 1 or envelope 2.
(please see the envelope section further on in the user guide.)
ENVELOPE POLARITY (5)
- determines whether the envelope modulates the filter cut-off positively or negatively.
ENVELOPE INTENSITY (6)
- determines how much envelope modulation is applied to the filter cut-off.
LFO MODULATION (7)
- determines how much LFO modulation is applied to the filter.
(Please see the LFO section further on in the user guide.)
FILTER KEY FOLLOW (8)
This is similar to key tracking, discussed in the oscillator section earlier.
When set to zero, the keyboard will not influence the filter’s cut-off at all,
but at higher settings, higher keys will sound brighter than lower keys.
CAUTION: Turning up the resonance can lead to a profound increase in
sound volume, perhaps unexpectedly. Please consider both your speakers
and your ears and use this feature cautiously.
12 Programming -Filter
CAUTION: When the filter cut-off is built up from zero using an envelope generator
with a long attack time, transient low frequency rumbles can occur when the filter’s
output slips from inaudible to audible. To avoid this issue, be sure to add a small
amount of attack time to the volume envelope. (Envelopes are discussed below.)
