Logic pro session player Drum Window Resize
If DRUM ICONS in the Logic Pro Session Player Editor are "Missing" - they are not. The Icons are just not able to fit in the center black window. It seems that Apple prioritized showing the full name of the track you asked the Drum Track to Follow.
So, if the name is very long - The Full name will show on the Right Side of the Black Window - but the DRUM ICONS on THE LEFT may get CUT OFF Be HIDDEN from View. I have found no way to make the Text Smaller, or to Resize the Window Larger -
SO, THE ONLY OPTION IS TO SHORTEN THE NAME OF THE TRACK YOU ARE ASKING THE DRUMS TO FOLLOW.
