EXS24 mkII modulation source reference

The table outlines sources available in the Src pop-up menu that can be used for real-time modulation of targets.

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 offers 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 Cutoff, the cutoff frequencies rise and fall, depending on how firmly 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 five octaves below the center point. An output value of +1 indicates five octaves above. Modulate the Cutoff destination with the Key source to control the cutoff frequencies of the filter with the keyboard position—as you play up and down the keyboard, the cutoff frequencies change. A modulation intensity of 0.5 proportionately scales cutoff 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 X uses these controllers for volume and pan automation of channel strips. Controller 11 is marked Expression. It has a fixed connection to this function, but it can also be used to control other modulation sources.
