PITCH FOLLOW
The VCF cutoff point alters depending on which key is played on the keyboard. This pitch follow can be
used to prevent any inconsistency in the harmonic content caused by pitch alteration. So effectively it is a
scale effect for the 1 Volt/Oct pitch tracking supplied to the filter. It’s nice to be able to choose between full
tracking, and no tracking at all. Play an arpeggio and adjust this and notice how it changes. It may seem
subtle to you now, but this can be very useful to a crucial sound.
RESONANCE
This is the filter resonance used to emphasize the cutoff point of the cutoff frequency. Lowering this will
allow more bass to pass though. Raising it will freak out the sound and it will begin to wail, or shriek. It’s a
wonderful thing.
ENV MODULATION
The ENV output singla will control the VCF cutoff point. Thus providing a filter envelope for each key
played. The ADSR will provide this Envelope, and you can adjust the response by changing things around
on the Envelope. Try it. A filter envelope is a wonderfully useful thing. Adjust the attack while the cutoff
frequency is quite low, and listen to how the filter changes over time while keys are played. This is central
to creating your own patches. Explore this. You might need it later.
POLARITY
This switch is to select the polarity of the envelope curve. Positive (up) means the ADSR will control the
frequency of the filter in a standard ADSR manner. Negative (down) indicates that the ADSR control will be
inverted. This can get strange, so flip the switch and play around with the envelope and see how it works.
It’s nice to be able to have a positive VCA envelope, and a negative VCF envelope, and/or the other way
around. Mess with this and learn.
