We have found a bug in the 1.963 update where if you set your foot pedal settings in the Utilities menu/ settings section of OnSong, they will not work or assign the wrong function to the foot pedal. You can set the foot pedal settings using the Foot Pedal icon in the menu bar and everything should work as it should. Here are the instructions on how to set your foot pedals:
Please do the following: Open OnSong--> Tap center of the screen to show the menu bar--> Tap on the foot pedal icon (next to the head phone icon)--> Scroll until you see the foot pedal configuration that you require--> Tap on a pedal on a pedal--> Assign and action--> Continue to do this until all the pedals are assigned an action--> Tap Close.
If you continue to have trouble, please contact us at firstname.lastname@example.org
