The upper area of the applet shows a panel of ‘Global’ settings for the entire group of connected interfaces, and a panel of ‘Unit’ settings which is assignable to each connected unit in turn, using the enclosed drop-list. These settings are concerned with general parameters such as sync source and sample rate selection, metering and buffering modes. An ‘Identify’ button causes all the LEDs on the selected box to light, to assist with identification in multi-unit systems. To the right, there are large buttons for loading and saving setups, and for on-line help.
