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
Return (or Enter) when the preset is selected.
Channel Count Menus
Note: The Channel Counts menus are generally not recommended
for use with Arrow. The menus are typically used with Apollo devices
and/or multi-unit systems that have higher channel counts than
Arrow.
The Channel Count menus (one each for number of inputs and number
of outputs) are used to change the number of Arrow I/O channels used
by Core Audio / ASIO. By default, the total number of input and output
channels for all 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 selected 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 channel 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 input channels used by Core Audio / ASIO is displayed.
Click the display to select a different input channel count from the menu.
# Outputs – The number of active output channels used by Core Audio / ASIO is
displayed. Click the display to select a different output channel count from the menu.
Note: Each Core Audio / ASIO stream uses host computer CPU resources. To
maximize CPU performance, do not set the channel counts higher than the
number of channels actually needed.
