cut-off frequency and RES (Resonance) controls the filter resonance. The
one exception to this is the combined LP+HP filter, for which the Res
knob controls the HP filter cut-off frequency. More on that further down.
FILTER TYPE
Filter Type, along with Filter Keyboard Tracking and Filter Drive is
selected using the Synth display. Press the Filter TYPE button and use
the three dials under the display to set these parameters as desired.
LP 24 & LP 12
Frequencies above the Filter Frequency setting will be attenuated,
frequencies below are not affected.
The LP12 setting provides a 12 dB/octave low-pass filter (also known as
a 2-pole filter), which retains more harmonics than the LP24 setting.
The LP24 setting, with an attenuation slope of 24 dB/octave, is a more
classic “synth filter”. It cuts out frequencies rather drastically, with a
slope of 24 dB per octave. A 24 dB filter is also known as a 4-pole filter.
Both LP Filters can use the resonance control to emphasize frequencies
around the filter frequency (cut-off frequency), making the sound thinner.
LP M
The LPM filter setting provides an emulation of the original transistor
filter from the famous Mini. This groundbreaking and much loved filter
design was created and patented in the 1960’s by Dr Robert A. Moog.
The M filter is a 4-pole, 24 dB/octave, resonating low-pass filter. The
character of the filter resonance is one detail that makes it stand out,
leaving more of the low end of the signal than on a traditional 24 dB/
octave low pass filter.
LP+HP
The combined low-pass/high-pass filter (LP+HP) consists of a 12 dB
low-pass and a 12 dB high-pass filter in parallell. The Filter Freq knob
controls the cut-off frequency of the LP filter and the Resonance knob
controls the cut-off frequency for the HP filter.
This combination is useful for tonal shaping of any source, allowing for
cutting the range between the two cut-off frequencies or for enhancing a
particular range with overlapping filter ranges.
HIGH PASS - HP
If HP (high-pass) is used, frequencies below the Filter Frequency setting
will be attenuated, frequencies above the cutoff are not affected. In
practice, this means that the sound will become increasingly thinner as
the Filter Frequency is increased.
BAND PASS - BP
The BP (band-pass) filter allows frequencies close to the Filter Frequency
setting to pass, while frequencies above and below the cutoff are
attenuated. This can for instance be used for producing narrow, nasal
or very “controlled” sounds - its exact character depending on filter
frequency and resonance settings.
KEYBOARD TRACKING
The Keyboard Track (KBD Track) parameter is also set from the Filter
Type display, using the middle dial.
The reason for controlling keyboard track is related to basic acoustics.
If the pitch of a waveform is raised, the harmonics naturally raise in
frequency as well. If the cutoff frequency is constant, the sound will be
perceived as getting “muddier” the higher up the keyboard you play. To
avoid this effect, use KBD TRACK.
KB TRACK SETTINGS
Off: The filter frequency cut-off point is not altered by the note played.
1/3: The cut-off frequency tracks the keyboard in a 1:3 relationship.
Play one octave higher and the cutoff frequency will move by 1/3 of an
octave.
2/3: The cut-off frequency tracks the keyboard in a 2:3 relationship,
play one octave higher and the cutoff frequency will move by 2/3 of an
octave.
1: The cut-off frequency tracks the keyboard at a 1:1 ratio.
