Hello, Can anybody point me in the right direction on how fader banks are pre programs in logic x and are they editable? I am having ongoing issues trying to map my controller to faders in logic. I am successful with mapping the first fader but when I “Learn” the next fader using the ”Selected track” option that switch’s to a numbered Fader Bank. I’m using an evolution UC33E controller which is not a recognized controller when scanned so I use the “recording lite” option. This is also happening to my Akai MPK? Thanks for any info.
