Variable Actions

Most actions are momentary. That means that you press a button or tap the screen to perform an action such as scrolling down or toggling tracks. However, OnSong supports variable actions when you use a MIDI Control Change, Note Event, or an analog input like an expression pedal. These let you adjust parameters, usually from 0-100% but may have addition options too.

You can review the Actions Menu for the variable actions that are not shown in each section. In addition, after selecting a variable action, a wrench icon will appear in the bottom right. This will let you configure settings for the variable action including:

Display On-screen

Determines if information is flashed on the screen as the parameter is changed. For instance, when adjusting volume, the current volume will be displayed as a percentage.

Invert Values

Inverts the information coming from the variable input. For instance, you may want to invert values when scrolling. This would allow the expression at 0% to represent fully scrolled down the page, while a value of 100% is scrolled up.

Use Absolute Values

Determines how values are sent. For instance, MIDI Control Changes can be values between 0-127. If the absolute value is used, OnSong will send a number from 2 through 127 as the value. This may be helpful if you want to target a specific section by number. However, the default is off which means amounts are relative from 0-100%. This means that OnSong would, in our previous scenario, choose a section based on the number of available section of the song where 100% would choose the last section and 0% would choose the first section.
