The higher parameter is “Overdrive curve.” In this case with a value of -64.
This parameter determines the characteristic of the Overdrive effect. Use the upper Data knob to adjust this parameter. With a set-
ting +00 normal clipping type of Distortion occurs. With at +ve value additional symmetrical distortion effects are introduced. With at
-ve value addition asymmetrical distortion effects are introduced.The range of this parameter is -64 to+64. This parameter is mem-
orised with a Program.
The lower parameter is “Oscs filt bypass”. In this case with a value of Off.
This parameter determines if the Oscillators & Ring modulator outputs actually pass through the Filter or not. This allows the noise
to be filtered independently of the Oscillators, which is particularly useful when creating drum sounds. When this parameter is set
to the On position, all the oscillators & the outputs of the Ring Modulators minus the Noise ( which is still going through the filter )
are routed past the filter, to the Amp envelope. When this parameter is set to the On position, all the oscillators, the outputs & the
Ring Modulators plus the Noise are routed to the filter. The range of this parameter is -64 to +63. This parameter is memorised with
a Program.
Page 6 looks like so:
The parameter is “Special type filter width”. In this case with a value of 000.
This parameter determines the spacing/offset in filter cutoff frequencies between the two elements of the “Special” filters. This is a
duplicate of the Filter width parameter that is displayed when the special page is active. The reason for this is that it was found to
be nice when editing for the display to jump back to this parameter when editing & as this parameter is duplicated here in this
menu it will do exactly that. This can provide “Formant” type filters & speech like qualities can be easily realised. The Filter width is
calibrated in semitones & allows specific offsets to be easily created. The range of this parameter is 000 to 127. Note that the
Resonance modulation Knob in the Filter Modulation Matrix actually modulates the “Filter width” parameter & not the resonance
when the “Special” filters are selected. The Resonance knob still retains its function as filter Resonance when in this mode. This
parameter is memorised with a program.
Adjusting the value of this parameter will alter the value in the Special page. It is not possible to have different values set in the 2
pages.
12dB - Button
18dB - Button
24dB - Button
These buttons select the slope of the cutoff curve of the Filter. Only one can be selected at once. The effect is similar to a “Q” con-
trol on a parametric EQ. In the 12db position the Cutoff Frequency slope is less steep so in a Low Pass Filter the higher frequen-
cies are not attenuated as much as they are in the 24 or 18db positions. This makes the resulting filtering in the 12db position
more subtle than the 24db or 18db positions which you should select if you want the Cutoff Frequency to be more obvious.
Low - Button
High - Button
Band - Button
These buttons select the type of Filter to be used in this program. All have a very different sound. Below is a description of what
parts of the sound the different Filters allow through the Filter.
The Low button configures the Filter into a Low Pass Filter. A Low Pass Filter allows harmonics below a set frequency to pass
through the Filter. Hence the name Low Pass Filter. The High button configures the Filter into a High Pass Filter. A High Pass Filter
allows harmonics above a set frequency to pass through the Filter. Hence the name High Pass Filter. The Band button configures
the Filter into a Band Pass Filter. A Band Pass Filter allows harmonics at a set frequency to pass through the Filter, the harmonics
above & below the set frequency do not pass through the Filter. Hence the name Band Pass Filter. The setting of these buttons is
memorised with a Program.
