The Quick Recall function in RedNet Control allows you to reload settings to a device (or devices) that you've previously saved using File > Device Save or File > Session Save.
A Device Load or Session Load file can be added to one of the 16 recall slots by going to the Quick Recall > Setup Quick Recall menu, after which it can be recalled either by selecting it from the Quick Recall menu, pressing a keyboard shortcut or by sending a MIDI Note/Sysex/Program Change message to the RedNet Control 2 virtual MIDI device.
