Filter Modulation Parameters
The filter modulation parameters control how each matrix
affects the filter response.
Cutoff Mod
64...+64
Determines the amount of influence each filter step has
on the cutoff frequency. The final value of the cutoff
frequency is calculated as the value of the Cutoff
parameter, plus any modulation applied by the position of
the active step multipled by the value of Cutoff Mod. In
other words, the higher the value of Cutoff Mod, the
larger the influence of the pattern on the resulting cutoff
frequency.
When this value is positive, the cutoff frequency is
increased when a step is in the upper half of the matrix,
and with negative settings, the cutoff frequency is
decreased when the step is in the upper half. Keep this in
mind when the filter does not behave as expected.
Resonance Mod
64...+64
Determines the amount of influence each step has on
filter resonance. This parameter works in exactly the same
way as Cutoff Mod.
Mode
Smooth / Env
The Mode switch allows you to control how the filters
behave between steps. The Smooth setting produces a
smooth, gradual change between steps, while Env gives
you more control over the changes. In Env mode the Rise
and Fall knobs are used like those found on a
synthesizer’s envelope generator, where Rise controls the
attack phase of the step change and Fall controls the
release phase.
You can create dramatic filter changes to the source audio
material when using these filter modulation parameters.
We encourage you to try out all of the different
possibilities that are available.
