Reply to Vestax Typhoon Mapping Traktor LE

Hi,

I got a Vestax Typhoon and Traktor LE and I would like to change the mapping for the "Song List" button on the controller.

Currently it opens the song list browser as long as you hold the button pressed. I would like to change it this way:

first click -> song list browser opens
second click -> song list browser closes

How can I do this ?

Thanks in advance.
