pub const AFTERTOUCH_PARAMETER: &str = "aftertouch";Expand description
The parameter ID of the aftertouch parameter. See CONTROLLER_PARAMETERS for more.
Aftertouch is a pressure sensor sent by some controllers.
This is the global version of the crate::events::NoteExpression::Aftertouch note expression event.
This controller parameter should affect all notes,
while the note expression event affects a single note. Note that hosts are free
to use a combination of this global controller with per-note controllers. This means
plug-ins must combine this global controller with the per-note controller to get the total
expression value.
