3 - PCI Card & Interfaces
The E-MU 0404 PCI Card
E-MU Digital Audio System 9
The S/PDIF out can be configured as either Professional or Consumer mode in the
Session Settings
menu. The 0404 PCI card can be connected to AES/EBU digital audio
systems through the use of a cable adapter. See AES/EBU to S/PDIF Cable Adapter for
details.
Important:
When
using any type of digital
I/O such as S/PDIF, you
MUST sample sync the
two devices or clicks and
pops in the audio will
result.
See
Using External
Clock
The S/PDIF input and outputs are usable at the 44.1kHz, 48kHz and 96kHz sample
rates. The word clock contained in the input data stream can be used as a word clock
source. See Using External Clock.
MIDI (

two or more devices together. Connect
MIDI Out
to external MIDI instruments and
connect
MIDI In
to a controller such as a MIDI keyboard.
Unlike S/PDIF, the MIDI cable does not carry audio data. In its most basic application,
MIDI tells a synthesizer when to start and stop playing specific notes. MIDI also carries
other information such as how hard the note was played, what sound to play, the
channel volume and many other commands. The most important thing to remember is
that MIDI contains CONTROL information, not the sound itself.
Information on the MIDI cable can be assigned to any one of sixteen channels so that
different musical lines can be assigned to play specific sounds or MIDI instruments.
To connect more than one MIDI instrument to the 0404 PCI card, the MIDI Thru port
on your synthesizer can be used. MIDI Thru carries an exact copy of the data on the
synthesizer’s MIDI input port. To find more information about MIDI, see page 75.
