GainControl Support


The latest version is 1.4, and can be downloaded here.


Big Sur: GainControl is not compatible with MacOS 11.1 yet. Key commands are working, but MIDI control is not.

If GainControl does not change the region gain, check that:

  • It's actually running, it's icon should be visible in the top menu bar of the Finder
  • The region inspector is open in Logic Pro. Currently a floating inspector window is not supported but I'm working on support for this
  • If you changed your System language settings, quit and restart GainControl


  • macOS High Sierra, Mojave, and Catalina
  • from Logic Pro X 10.2 to 10.6.1
  • Japanese and Chinese languages not supported


  • Unpack the .zip file
  • Double click the .pkg file
  • Open GainControl


The first time you use GainControl, it will ask permission to control System Events.

  • Click 'OK'
  • Click 'Open System Preferences'
  • Unlock to make changes
  • Enable the checkbox next to GainControl

If for some reason GainControl does not ask for Accessibility permissions, you can add it manually:

  • Open System Preferences -> Security & Privacy
  • Go to the tab 'Privacy'
  • Select 'Accessibility' from the list
  • Unlock to make changes
  • Click the plus sign and add GainControl from the Applications folder

When you use GainControl for the first time in Logic Pro, it will ask permission to operate on Logic. 


    • From the menu bar icon, open Preferences
    • Enter the license you received and click Activate
    • If you need assistance, please contact us.

    A single license allows you to install it on three different systems.


    By default, GainControl starts when you login. You can change this in the Preferences, which you can open from the top menu bar icon.


    PlugSearch runs as a background menu-bar application. You can find it's icon in the top right menu-bar. From there, you can access Preferences and quit GainControl.


    Use the key commands to change the gain of selected audio regions. You can change the key commands in the preferences window of GainControl.

    You can also use MIDI messages to change the gain. You can set the input port and CC number in the preferences.
