EXS24 mkII modulation source reference
The following modulation sources are available in the Src pop-up menu:
Source Comments
Side Chain Side Chain modulation uses a side-chain signal as
a modulation signal. The side-chain source can be
chosen from the Side Chain pop-up menu in the
header of the plug-in window. It is fed to the internal
envelope follower, which creates a modulation value
based on the current side-chain input signal level.
Maximum Max sets the value of this source to +1 (an internal
value that indicates the maximum possible amount
for this source). This oers interesting options for
controlling the modulation intensity with all possible
via values.
ENV 1 Envelope Generator 1 is used as a source.
ENV 2 (Amp) Envelope Generator 2 is used as a source. Env 2 always
controls the level of the overall sound.
LFO 1 LFO 1 is used as a source.
LFO 2 LFO 2 is used as a source.
LFO 3 LFO 3 is used as a source.
Release Velocity The modulation occurs when you release a key
(this requires a keyboard that sends release velocity
information).
Pressure Pressure (also known as aftertouch) serves as a
modulation source. EXS24 mkII reacts to poly pressure
(polyphonic aftertouch).
Note: If you set the destination to Cuto, the cuto
frequencies rise and fall, depending on how rmly you
press a key on your touch-sensitive MIDI keyboard—
after the initial keystrike.
Pitch Bend The pitch bend wheel is used as a modulation source.
Key Kybd (Keyboard) outputs the keyboard position (the
MIDI note number). The center point is C3 (an output
value of 0, used internally by EXS24 mkII). An output
value of −1 indicates ve octaves below the center
point. An output value of +1 indicates ve octaves
above. Modulate the Cuto destination with the Key
source to control the cuto frequencies of the lter
with the keyboard position—as you play up and
down the keyboard, the cuto frequencies change.
A modulation intensity of 0.5 proportionately scales
cuto frequencies with keyboard note pitches.
Velocity Velocity serves as a modulation source.
--- Disables the source.
MIDI Controllers 1–120 The MIDI controller you choose serves as a
modulation source.
Controllers 7 and 10 are marked Not available. Logic
Pro uses these controllers for volume and pan
automation of channel strips. Controller 11 is marked
Expression. It has a xed connection to this function,
but it can also be used to control other modulation
sources.
