Note Events

Note events in MIDI are used to play an instrument by sending note on and off commands. They can also be used for general messaging to apps such as OnSong.


To setup a note event in the MIDI editor, choose Note in the type section.


The channel determines which MIDI channel the note event is sent or received on. By default, OnSong will receive or send on all channels. Use the plus and minus buttons to choose a specific channel if necessary.


Pick a note to send or receive by tapping on the None option. OnSong will display a list of notes including their numeric representation in MIDI (0-127), as well as the letter, enharmonic preference, and octave of the sound.


When sending note events, the velocity of the note can also be set. Tap on the keyboard icon to enter a velocity value manually, use the slider to quickly select a velocity, or tap on the value on the right to select from a list. By default this is set to 127.

Note that OnSong does not send nor receive MIDI note off commands when sending note events to perform actions.
