Push 3 Manual request

[eblomquist]

The P3 manual could be clearer on how to add plugins to tracks without replacing the existing ones. Essentially some additional info contrasting the Add button with the Replace button.

It’s not super obvious at first.

Also it could use more info on what the foot switch ports are for. It took some digging to find out that expression pedals don’t work, but there was nothing that I could find about what the switch type pedals can do on Standalone.

Thanks.
