Apollo Software Manual Chapter 6: Working With Apollo 100
PT Mode
PT Mode facilitates Pro Tools’ Hardware Inserts feature by inserting NULL (empty) val-
ues at Apollo inputs 1–2 so line input and output channel numbering within Pro Tools
is aligned. The setting also optimizes Apollo’s I/O channels to accommodate the 32 I/O
channels available in Pro Tools.
Note: PT Mode is unavailable with Apollo Twin.
How PT Mode changes Apollo’s I/O numbering
Enabling PT Mode
To enable PT Mode, click the PT Mode checkbox in the global
interface settings area in the Interface panel within the Con-
sole Settings window.
Changes To I/O Complement
Important: Enabling PT Mode changes the driver I/O complement. Quit all audio
applications before changing the PT Mode setting.
DAW I/O driver numbering
PT Mode changes Apollo’s driver I/O numbering and names. If a DAW project saved with
PT Mode disabled (or saved prior to UAD v7.0.0) is subsequently opened when PT Mode
is enabled, the DAW’s channel I/O assignments may need to be adjusted.
The specific Apollo channel numbers and names when PT Mode is active are listed in the
PT Mode tables in
“Driver I/O Tables” on page 118 .
Optimized Apollo channels in Pro Tools
Because Apollo’s I/O channel numbering exceed the 32 channels available in Pro Tools
in certain configurations (such as when multi-unit cascading), the available I/O channels
are optimized when PT Mode is active.
Note: Channel numbers higher than 32 are unavailable in Pro Tools when PT
Mode is active. The specific channels that are unavailable in Pro Tools are dis-
played in italics within parentheses in the PT Mode tables in
“Driver I/O Tables”
on page 118 .
