I/O Presets Functions
The following I/O preset functions are available:
Open – Opens the operating system’s standard “Open File” dialog for loading existing I/O
preset files from disk.
Save – Saves the current modified I/O preset file in place. If the preset was not previously
saved (if the file doesn’t exist), the Save window appears so it can be named.
Save As – Opens the Save window so the current settings can be named and saved to
disk as a new I/O preset file.
Load – Loads the I/O preset that is currently selected within the I/O Presets window (a
preset is selected when highlighted in blue).
Tip: An I/O preset can also be loaded by double-clicking the preset or typing Re-
turn (or Enter) when the preset is selected.
Channel Count Menus
The Channel Count menus (one each for number of inputs and number
of outputs) are used to change the number of Apollo I/O channels used
by Core Audio.
By default, the total number of available input and output channels, for
all detected Apollo devices, are displayed.
The primary reason to change the channel counts is to accommodate the
32 I/O channels available within Pro Tools. When 32 channels are select-
ed for Apollo I/O (PT Mode), any Apollo I/O can still be used by virtually
remapping the I/O so the desired channels fit within the available chan-
nel count.
Important: These menus change the driver I/O complement. Quit all
DAW applications before changing the Channel Count settings.
# Inputs – The number of active Apollo input channels used by Core
Audio is displayed here. Click the display to select a different input channel count from
the menu.
# Outputs – The number of active Apollo output channels used by Core Audio is dis-
played here. Click the display to select a different output channel count from the menu.
Note: Each Core Audio stream uses host computer CPU resources. To maximize
CPU performance, do not set the channel counts higher than the number of chan-
nels actually needed.
Device Name Display
The Device Name of the Apollo device is displayed in the INPUT and OUTPUT columns
so each Apollo unit can be readily identified in multi-unit setups. Each device is color-
coded for easier identification.
