How To Use
How do I use GainControl?

GainControl allows you to change the gain and fades of audio regions in Logic Pro. You can set the key commands in the GainControl Preferences window.

Here is how you use GainControl:

  • In Logic Pro, make sure that the Inspector is open (in the sidebar or floating)
  • Select an audio region
  • Use the GainControl key commands to change the gain or apply/remove fades

The gain can be changed by 'small' or 'normal' amounts. The fade length can be increased or decreased by a fixed amount, that can be set to a custom value.

Can I disable specific GainControl key commands?
Yes. Select a key command in the preferences window, and hit 'backspace'. The key command is now deleted.
How to use a MIDI controller with GainControl.
You can use a MIDI controller to change the gain of audio regions. In the GainControl preferences window, select the input port of your MIDI controller, and the MIDI CC number that you would like to use.
Troubleshooting
GainControl does not change the gain/fades.

If GainControl does not change the region gain or fades, check that it's actually running, it's icon should be visible in the Finder task bar.

Under some circumstances, the Accessibility privileges may get corrupted. In that case, remove GainControl from the Accessibility list under System Preferences -> Security & Privacy -> Privacy. Restart your system and open GainControl, it will ask for permission to be added again.

Changing the gain of two regions with different gain settings sets them to the same gain value
Replace all key commands that are using 'SHIFT'. This causes Logic Pro to set the gain value of multiple regions to the same amount.
