Set a hold button

[doriam]

Hi, I wanted to set one of the buttons of the Keylab Essential 49 to create a HOLD/Latch function without a computer. It is possible to do this with some setting on the MIDI Control Center?
I wanted to use it with external power as a controller for a Volca FM.

I've already tried this but didn't work: https://i.imgur.com/1p8Ak5c.png
