Recording To and From Digital
Devices
The 888|24 I/O, the 882|20 I/O and the
1622 I/O each provide S/PDIF (RCA) connectors
for digital input and output. The 888|24 I/O also
provides AES/EBU (XLR) connectors. The ADAT
Bridge I/O adds optical input and output so that
you can digitally transfer as many as sixteen
tracks at a time to or from ADAT decks.
Setting Digital Format and Clock
Source
Before recording from a digital source, make
sure you have enabled the appropriate Clock
Source and Digital Format in the Hardware
Setup dialog. For example, if you want to record
from a DAT machine connected to your S/PDIF
RCA inputs on an 888|24 I/O, select S/PDIF from
the Clock Source options. If using multiple au-
dio interfaces, be sure to configure the appropri-
ate interface in the Hardware Setup dialog.
Using Output Pairs
Because of the way that outputs function in
Pro Tools, each track looks for a stereo output
pair. In order to record to eight ADAT tracks, you
have to send four pairs of Pro Tools tracks (each
pair panned hard left and right) to four pairs of
ADAT Optical Digital outputs.
Recording MIDI
To configure a MIDI track for recording:
1 (Macintosh Only) Choose MIDI > Input De-
vices and make sure your input device is selected
in the MIDI Input Enable window.
2 Choose File > New Track and specify 1 MIDI
Track, then click Create.
3 In the Mix window, click the track’s MIDI De-
vice/Channel Selector and assign a device and
channel from the pop-up menu.
4 You can assign a default program change to
the track by clicking the Program button in the
Mix window and making the necessary selec-
tions for program and bank select, and then
clicking Done. Default program changes are
sent when playing a track.
5 In the Mix Window, record-enable the MIDI
track.
6 Make sure MIDI > MIDI Thru is selected, then
play some notes on your MIDI controller. The
MIDI instrument assigned to the track should
sound, and the track’s meters should register
MIDI activity.
