PaulHand It should be possible, just program your foot pedal switches to the correct action in settings, i use this all the time without problems, what foot pedal are you using?
ST3 makes it very easy to program your pedals, so make sure you do this first.
Checkout the instructions in ST3 if you need details.
If you still have issues Peter will definitely help you.
Ah ! i just thought about what you might be struggling with as i had the same issues, if you are using Queue mode then the foot pedal option as you use to use it doasnt function the same, my work around that was to use playlists only and disable queue altogether this then behaves the same way you probably liked Before , you will be able to move down your song list with foot pedalls and choose your next song, this was my big gripe with new ST3.
Its all coming back to me , i dont use queue at all as i preffer the old way as it works better for me.
Hope this helped.
