Filter
Filter
The V-Station’s filter is what is known as a ‘Low Pass’ type. This type of filter is musically the
most useful for the majority of sounds.
FREQ Knob
This controls the basic cutoff frequency of the filter. Set fully clockwise, the filter is wide open
allowing all frequencies (harmonics) produced by the oscillators to pass through.
Cutoff frequency
As the knob is turned anticlockwise, the filter closes, cutting out harmonics, starting with the
highest, then increasingly lower ones until only the fundamental (or nothing at all is allowed to
sound - fully anticlockwise).
Cutoff frequency
Note : If there is silence when the VOLUME knob is turned up, it is most likely that the filter is
fully closed. Turn the FREQ knob clockwise to open the filter.
RES Knob
This knob controls the resonance of the filter. The control will boost frequencies at the cutoff
frequency. On some synthesizers, this control is known as Emphasis since it will emphasise
certain frequencies. At the zero position (i.e. fully counter-clockwise) there is no effect.
Turning clockwise slowly introduces the emphasis.
Set fully clockwise, the filter will begin to self - oscillate, producing a new pitched element
(similar to feedback on an electric guitar).
Note : At least a small signal must be fed into the filter in order for the resonance to take effect.
It is not possible for the filter to self - oscillate if no signal at all is fed into it.
If the V-Station produces a high pitched whistling sound, it is probably due to this knob is being
adjusted too far clockwise. If this self-oscillating effect is not desired, keep the resonance
control away from the extreme clockwise setting. Increasing the resonance is very good for
bringing out modulation (movement or change) in the filter cutoff frequency, such as in Acid
bass lines and other very edgy sounds.
Q NORM Knob
Controls the Resonance Normalise. At zero, when resonance is applied, the main audio signal
will remain at normal levels. Adjusting clockwise will reduce the signal level in relation to the
resonance level.
This feature enables the filter to emulate many of the classic filters such as the Moog type,
Oberheim type and Roland TB303* type.
