By resetting the database via the XLN Installer, manually re-selecting the layout, or building a custom "Top" tier routing preset, you will be back to producing within 3 minutes. If all else fails, a clean reinstall of Addictive Drums 2 (backup your kits first!) always restores the default bus layouts.
If the error triggers here, it means your DAW’s track limit or bus configuration isn't matching AD2’s output template. Try loading a "Stereo" instance of the plugin first, then switching to "Multi-Out." Summary Checklist addictive drums 2 could not find bus layouts top
