VCF MOD
(MODULATION OF THE VOLTAGE CONTROLLED FILTER)
SOURCE (SOURCE SWITCH)
This switch allows you to choose which Modulation Source will be applied to
the filter.
EG: EG is short for Envelope Generator. When the switch is in this position,
the Attack, Sustain, and Decay characteristics of the Envelope Generator
will be used as the modulation source.
LFO: LFO is short for Low Frequency Oscillator. The LFO produces a cyclic
change that can be used to create a repeating effect. When the switch is in
this position, the LFO will be used as the modulation source.
AMOUNT (AMOUNT KNOB)
Once a modulation source has been selected, the Amount knob can be used to
control the depth of the modulation effect.
POLARITY (POLARITY SWITCH)
The Polarity of the VCF modulation source can be reversed. That is, the nor-
mally negative portions will become positive, and vice-versa. For example,
instead of using the Attack portion of the EG to boost the Filter Cutoff frequen-
cy, inverting the polarity will allow the Attack portion to lower the Filter Cutoff
Frequency. Just be aware that if the Cutoff is already set low, inverting the EG
polarity might close the Filter too far, making it appear as if the Werkstatt is not
creating any sound.
[ + ]: Positive is the normal polarity for the VCF Modulation Source.
[ – ]: The negative position reverses the VCF Modulation Source.
Filter Modulation changes the value of the Filter’s Cutoff Frequency. Either
the EG or the LFO can be used as a Filter modulation source. When the EG is
chosen as the modulation source, the polarity of the EG can be reversed for
even greater sound creation options.
