Is there a way to prevent the PC/Mac error sound from being heard?
Yes.
You can change the PC/Mac sound settings so you won’t hear the error sound.
■ Windows
Go to [Control Panel] > [Sound] > [Program Events] and turn off all sound settings.
■macOS
Open [System Preferences] > [Sound Panel] > [Sound Effects] and change the device to something other than the DDJ-FLX2.
