The filters are 2 pole filters with rolloff curves at 12 dB per octave. If both filters
are programmed with identical parameter values, they become a single 4 pole filter
with a rolloff at 24 dB per octave, perfect for those classic analog synth sounds.
The Filter Tracking parameters, programmed on pages 3 and 4, ensure that the
Cutoff Frequency does not remain fixed for all the notes of a Sound, but moves
according to the note played. Tracking can prevent, for example, the “cutting” of
the higher notes of a Sound which is affected by a Low Pass Filter.
In the case of DC and DO Sounds, the filters have a complex envelope that allows
them to vary the quality of the timbre over time. In SO Sounds the envelope is not
present. In the former case, the filters are dynamic, while in the latter the filters are
static.

Type Filter type. ( S. information on the types of filters in “Notes and suggestions” at the end of the
chapter). “Off” means that the filter is not active.
Value range: Off, Low Pass, High Pass, Band Pass, Parametric Boost, Parametric Cut.
Cutoff Frequency Filter cutoff frequency, or frequency at which the filter intervenes. The Cutoff Frequency is
the same for all the notes of a Sound, unless you programme Filter Tracking ( s. ).
The Cutoff Frequency can be modified by the Filter Envelope, the Key On Velocity, the
Aftertouch, the Lfo and by the Midi Controllers 14, 15, 20.
Default: 0. Value range: 0 ... 191.
Resonance Resonance creates a peak of emphasis at the Cutoff frequency. Resonance with a high
value can place the filter on “auto-oscillation”, producing a whistling sound rich in harmon-
ics. To avoid distortion, assign a negative value to the “Out gain” parameter.
Resonance can be modified by Key On Velocity.
Value range: 0 ... 127.
Cutoff dynamic sensitivity Links the Cutoff Frequency to Key On Velocity. Positive values increase the Cutoff Fre-
quency by playing harder (the filter opens allowing more partials to pass and the sound
becomes brighter), negative values produce the inverse effect (the filter is closed and the
sound becomes “dull”). The value 0 does not affect the Cutoff Frequency.
Value range: -7 ... +7.
Resonance dynam. sens. Links Resonance to Key On Velocity. Positive values enhance the Resonance with in-
creased dynamic force while negative values give the inverse effect. The value 0 does not
affect the Resonance.
Value range: -7 ... +7.
Cutoff touch sensitivity Links the Cutoff Frequency to Aftertouch. Positive values increasingly open the filters with
increased Aftertouch pressure, negative values have the inverse effect. The value 0 does
not affect the cutoff frequency.
Value range: -7 ... +7.
Out gain Increases or attenuates the output level of the signal. This parameter has two applications:
(1) attenuation of the output level when the Resonance or a Parametric Boost produces a
signal distortion,
(2) intensification of the signal when a Parametric Cut attenuates the
signal, or when you want to create a distorted signal.
Value range: -2 ... +2.
Important: The “Out Gain” parameter may produce signal peaks that can distort the signal
or even damage the audio system. Use this parameter with caution.

The parameters are identical to those described above, but applied to Filter 2.
Suggestion: To copy the parameters of Filter 1 page to the Filter 2 page and obtain a single
4-pole filter, use the Clipboard in the following manner:
