In zero position the cutoff frequency is not effected by the key dynamics. With values above 0 the
cutoff frequency is moved up and with values below 0 down.
LOW-PASS FILTER PARAMETERS: MENU PAGES 12 - 18
On these menu pages parameters will be presented which can be adjusted from the user surface.
This manual covers the resonance filter more thoroughly in the chapter, "The function of the
controls and buttons." The following is the only other parameter of the low-pass filter that is not
found on the surface.
LOW PASS FILTER DYNAMIC: MENU PAGE 19
On menu page 19 of the filter menu you can adjust how strongly the key velocity influences the
low-pass cutoff frequency:
Edit Part1 FILTR
<19> LPF-Dyn: +0
In zero position the cutoff frequency is not affected by the key velocity. With values above 0 the
cutoff frequency is pushed up and with values below 0, down.
LOW-PASS FILTER KEY FOLLOW: MENU PAGE 20
The parameter "key follow" varies the low-pass cutoff frequency depending upon the played pitch.
By using this parameter you can make the filtering of sounds dependant on those sounds
themselves.
Edit Part1 FILTR
<20> LPF-Key: +0
At 0 the keyboard scale is turned off. With values above 0, higher notes will open the filter further
than lower notes. With values below 0 the filter will behave in reverse. Higher keys (to the right) on
the keyboard cause a lowering of the cutoff frequency.
FILTER MODULATIONS: MENU PAGES 21 - 25
On these menu pages you can adjust how the cutoff frequencies of both filters are modulated by
LFO-3. Most parameters are found on the surface of the POLYMORPH. They are explained in
section "LFO 1-3 modulation oscillator" of "The function of the controls and buttons" chapter. Only
menu pages 24 and 25 offer extra possibilities. Here you can individually adjust the low-pass and
high-pass filter, how strong and with which polarity the cutoff value will be modulated.
Edit Part1 FILTR
<24>LFO>HPF: +63
Edit Part1 FILTR
<25>LFO>LPF: +63
The most effective filter modulation is two that works the filters against each other. The low-pass
filter has a positive value and the high-pass filter a negative value. With the parallel filter you can
have a very effective phasing effect.
