Sampler modulation Sources in MainStage
The table outlines sources you can choose in the Source pop-up menus of the Mod Matrix pane that can be used for real-time modulation of Targets. Also see Sampler modulation Targets and Sampler modulation Via sources.
Source | Comments | ||||||||||

None | Disables the source. | ||||||||||
Side Chain | Side Chain modulation uses the side-chain signal level as a modulation signal. The side-chain source is chosen from the Side Chain pop-up menu in the plug-in window header. 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. | ||||||||||
Random | A random value generator is used as a source. Note: The random value updates each time a MIDI note-on message is received. | ||||||||||
LFO 1 - 4 | The LFO you choose is used as a source. | ||||||||||
Envelope 1 - 5 | The Envelope Generator you choose is used as a source. | ||||||||||
Key | This source outputs keyboard position (MIDI note number). The default center point is C3. A value of −100 indicates five octaves below C3. A value of +100 indicates five octaves above. Modulate the Cutoff target 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 Amount value of zero proportionately scales cutoff frequencies with keyboard note pitches. | ||||||||||
Velocity | Velocity serves as a modulation source. | ||||||||||
Release Velocity | The modulation occurs when you release a key (this requires a keyboard that sends release velocity information). | ||||||||||
Pitch Bend | The pitch bend wheel is used as a modulation source. | ||||||||||
Aftertouch | Aftertouch (also known as keyboard pressure) serves as a modulation source. Sampler reacts to mono and poly aftertouch. Note: If you set the target 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. | ||||||||||
Mod Wheel | Your keyboard Modulation Wheel controller is used as a modulation source. | ||||||||||
MIDI Controllers 2–119 | The MIDI controller you choose serves as a modulation source. MainStage uses controllers 7 and 10 for volume and pan control 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. | ||||||||||
