Chapter 21 ES2 277
Cut1inv2
Cut1inv2 (Cutoff 1 normal and Cutoff 2 inverse) simultaneously modulates the Cutoff
frequencies of the first and second filters inversely (in opposite directions). Put another
way, while the first filter’s Cutoff frequency is rising, the Cutoff of the second filter will
fall—and vice versa.
Note: In cases where you have combined Filter 1, defined as a highpass filter, and Filter
2 (which always works in lowpass mode) in Serial mode, both will serve as a bandpass
filter. Modulating the Cut1 inv 2 target will result in a modulation of the bandpass filter’s
bandwidth in this scenario.
FltBlend
FltBlend (Filter Blend) modulates the FilterBlend (the cross-fading of the two filters), as
described in “Filter Blend and Signal Flow” on page 263.
Note: If FilterBlend is set as a target in one or several Router channels, the modulation
data for both filters will be calculated—even if the FilterBlend parameter is set to 1.0 or
+1.0. As such, you should be careful when choosing FilterBlend as a modulation target
because it may increase the need for processing power.
Amp
This target modulates the dynamic stage, or level (the voice’s volume). If you select
Amp as the target and modulate it with an LFO as the source, the level will change
periodically, and you will hear a tremolo.
Pan
This target modulates the panorama position of the sound in the stereo or surround
spectrum. Modulating Pan with an LFO will result in a stereo or surround tremolo (auto
panning).
In Unison Mode, the panorama positions of all voices are spread across the entire
stereo or surround spectrum. Nevertheless, pan can still be modulated, with positions
being moved in parallel.
Note: The extended Surround Range parameter defines the angle range resulting from
modulation values. As an example: if pan is modulated by the maximum amount of an
LFO (using a sawtooth waveform), a Surround Range value of 360 ° results in circular
movements of the voice output.
Diversity
This parameter (only available in surround instances of the ES2) allows you to
dynamically control how much the voice output is spread across the surround
channels. Negative values reduce this effect. See the Surround chapter of the
Logic Pro 8 User Manual for details on surround terminology and use.
