How to activate tuner from MIDI Controller FCB1010?

I don´t know if it helps, but this webpage definitely helped me to discover which CC# code each footswitch of my midi controller was sending.

In order to active the tuner, you have to use CC#15 as mentioned.

I have the same problem with mine

Can confirm on a brand-new device right from the store.
