The element is capable of reading the input of various MIDI devices connected to a PC. MIDI is a commonly-accepted protocol for communication with digital musical instruments, like a MIDI piano keyboard. The MIDI Input element can record a instrumental music played in real-time as a sequence of notes.

Description ¶

On onset of the parent event the MIDI input element starts to reads real-time input of a MIDI Device and record all received notes. The each note information includes the MIDI channel number, note name, playback start time, duration, octave number, note's sound frequency and button press velocity (or volume). The element can also detect presses of the control buttons, e.g. program change. The recorded notes and events can be easily accessed in snippets and logged. The element is designed for experiments, where participants' input is produced by playing a music with MIDI compatible instruments.
