DigiGain is an optional volume control applet that allows you to control the meter output of your Pro Tools hardware as well as control the monitoring input levels of the WaveDriver independently from your third-party audio applications. By default, the master level is se to 0 dB. DigiGain is not available as a volume control on the Windows task bar. As a result, the following setting will be disabled in the Multimedia control panel (Audio tab). "Show volume control on the taskbar," the playback volume control, and the recording volume control will all be disabled.
