Other Logic Pro ES2 modulation targets
The table outlines all other modulation targets.
Target Comments
Amp This target modulates the dynamic stage, or level of voices. If you select
Amp as the target and modulate it with an LFO as the source, the level
changes periodically, and you hear a tremolo.
Pan This target modulates the panorama position of the sound in the stereo
or surround spectrum. Modulating Pan with an LFO results 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. The extended Surround Range parameter defines the angle range
resulting from modulation values. For example, if panorama 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 (available only in surround instances of the ES2) enables
you to dynamically control how much the voice output is spread across the
surround channels. Negative values reduce this effect.
LFO1Asym (LFO1 Asymmetry) can modulate the selected waveform of LFO1. If a
square wave, it changes pulse width. If a triangle wave, it sweeps between
triangle and sawtooth. If a sawtooth wave, it shifts its zero crossing.
LFO1Curve This target modulates the waveform smoothing of the square and random
wave. If the LFO is using a triangle or sawtooth wave, it changes between
convex, linear, and concave curves.
Scaled Logic Pro ES2 modulation targets
All modulation targets outlined in this table result in a scaled modulation, which means that
the target parameter value is multiplied by the modulation value. This works as follows:a
modulation value of 0.0 results in no change, a modulation value of +1.0 equals a 10x
multiplication, and a modulation value of −1.0 equals a multiplication by 0.04.
Target Comments
LFO1Rate This target modulates the frequency (rate) of LFO1. You can automatically
accelerate or slow down LFO1 rate by modulating the LFO1Rate target
with one of the envelope generators (ENV) or with LFO2.
Env2Atck (Envelope2 Attack) modulates the Attack time of the second envelope
generator.
Env2Dec (Envelope2 Decay) modulates the Decay time of the second envelope
generator. In cases where you’ve selected Env2Dec as the target and
Velocity as the source, the duration of the decaying note is dependent on
how hard you strike the key. Selecting Keyboard as the source results in
higher notes decaying more quickly (or slowly).
Env2Rel Env2Rel (Envelope2 Release) modulates the Release time of the second
envelope generator.
Env2Time Env2Time (Envelope2 All Times) modulates all ENV2 time
parameters:Attack, Decay, Sustain, and Release times.
