- From the Finder task bar GainControl icon, open the GainControl Preferences
- Enter the license you received and click Activate
Yes you can, you can install GainControl on any system you personally own. There's no online hardware ID check, just me trusting you to handle this license with care.
By default, GainControl starts when you login. You can change this in the GainControl Preferences, which you can open from the Finder task bar icon.
GainControl runs as a background Finder task bar application. You can find it's icon in the top right Finder task bar. From there, you can quit GainControl.
To uninstall GainControl:

- open a terminal and type: defaults delete com.speakerfood.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.
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.
