Control Change

Control changes in MIDI are sent from pedals, knobs, and sliders, and are used to control the dynamics of music. They can also be used for general messaging to apps such as OnSong.

Type

To setup a control change in the MIDI editor, choose Control in the type section.

Channel

The channel determines which MIDI channel the control change 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.

Control

Pick a control to send or receive by tapping on the None option. OnSong will display a list of control values 0 through 127 with known controls named in the list.

You can rename controls when picking them by tapping on the Edit button and then tapping on the name of the control.

Value

When you are sending a control change, you can also choose the value to send from 0 to 127. This can be adjusted with the slider or by tapping on the value on the left to pick a new value from a list.

Latching On/Off

Toggle this switch to switch between the configured value and zero each time the action is sent.
