There is a Toggle Crossfader FX command. In this example, I mapped it to the [~ `] key.
MIDI:
I added the Toggle Crossfader FX command to my custom DDJ-FLX4 mapping. Unfortunately, I couldn’t add it to the built-in Algoriddim mapping. The Algoriddim mapping restricts access to both the command and the hardware button on the FLX4.
