5–2: Multi Filter
This page is available only when the Filter A Type is set to
Multi Filter.
What’s a Multi Filter?
Standard multimode filters generate lowpass, highpass, and
bandpass filters simultaneously - but only allow you to use
one of them at a time.
The Multi Filter gives you access to all three filter modes
simultaneously, in any combination, along with the dry input
signal. You can choose from a large number of preset
combinations, or create your own complex filter modes
using the Manual controls.
This is capable of some cool sounds in and of itself, but
things really get interesting when you use the Crossfade
controls. These allow you to crossfade between two of these
filter settings (Mode 1 and Mode 2), using AMS sources
such as EGs, LFOs, or real-time controllers.
5–2a: Filter A
Bypass [Off, On]
Frequency [00…99]
Fine [–99…+99]
Resonance [00…99]
These are the same as the similarly-named parameters on the
Filter Basic page, as described under “5–1b: Filter A” on
page 235.
Edits to the values on this page will be reflected on the Filter
Basic page, and vice-versa.
5–2b: Mode Crossfade
Mode 1 [List of filter types]
This sets the filter type for Mode 1.
Low Pass, High Pass, Band Pass, and Band Reject are the
standard filter types. For more information, see “Filter
Type,” on page 235.
The following types combine two or more filters at equal
volumes. Dry is the un-filtered input signal. The minus sign
(“-”) indicates when the phase of a filter is reversed: LP+BP,
LP-BP, LP-HP, BP+HP, BP-HP, Dry+LP, Dry-LP,
Dry+BP, Dry-BP, Dry+LP-HP, Dry+LP-BP, Dry+BP-LP,
Dry+BP-HP, Dry+HP-LP, Dry+HP-BP, LP+HP+BP.
All On uses the Low Pass, High Pass, Band Pass, and Dry
signals at equal volumes.
Manual 1 lets you create your own mix of the filters. For
more information, see “5–2c: Manual 1,” below.
Mode 2 [List of filter types]
Mode 2 has the same selections as Mode 1, except that the
list ends with Manual 2 instead of Manual 1.
Mode 1-2 Crossfade [0…99]
This fades between the Mode 1 and Mode 2 settings.
0 is all Mode 1, 99 is all Mode 2, and 1-98 are intermediate
values between the two Modes.
AMS [AMS Sources]
This selects a modulation source to control the Mode 1-2
Crossfade. For a list of AMS sources, see “Alternate
Modulation Source (AMS) List” on page 901.
Intensity [–99…+99]
This controls the depth and direction of the Mode 1-2
Crossfade modulation.
Intensity Mod AMS [List of AMS Sources]
This selects an AMS source to modulate the intensity of the
main Mode 1-2 Crossfade AMS.
For instance, you can set AMS to use one of the LFOs, and
then set the Intensity Mod AMS to JS -Y. You can then use
the joystick to modulate the amount of the LFO.
