Before proceeding please be sure your firmware is updated on your StudioLive and that you are using the latest Universal Control:

This article covers why your StudioLive has issues when moving fader 1 results in faders 9, 17 & 25 moving at the same time. 

When you set up your Control Surfaces in Logic Pro X depending on the mixer you have you are required to setup Mackie Control and either 1, 2 or 3 Mackie Control Extenders. 

To know exactly how many you required for the StudioLive you are using please consult page 3 of the Logic X Pro DAW Mode Setup Guide

  1. In Logic Pro X open
  2. Logic Pro X > Control Surfaces > Setup
  3. Ensure that after you create the required amount of control surfaces that your control surfaces are HORIZONTAL and not VERTICAL

You also need to ensure that your "Fader Bank Offset" value is correct. 

  • EXT Main should be set to 0
  • EXT 1 should be set to 8
  • EXT 2 should be set to 16
  • EXT 3 should be set to 24

To change these values "double click" and set them as desired.
