Hi,
I bought alesis VI25 midi controller and I tried to assign its buttonts to the button cell of ACT MIDI Controller.
But there is no MIDI Learn fuction for it.
Who know this way?

I found the way by myself. It's very simple. hh
For MIDI Learn, we must click the bottom of a cell, not upper.
It is different from other kinds of cell(above).
