= Source "MIDI Script" [[source-midi-script]] This source is feedback-only and exists for enabling more complex feedback use cases such as controlling LCDs that are not yet supported by the xref:sources/midi/display.adoc[]. It lets you write an EEL or Luau script that will be executed whenever ReaLearn "feels" like it needs to send some feedback to the MIDI device. == Kind menu Whether to use the EEL or Luau language. == Script field The script. Is disabled if the script contains more than one line. See xref:further-concepts/source.adoc#midi-source-script[] for details. == More button (…) Opens the script in a separate window (for multi-line scripts). TIP: Prefer the xref:sources/midi/display.adoc[] over this one whenever possible. It's easier to use.
