Creative 0404 Using MIDI Thru, MIDI In, MIDI Sound Module, Digital Connections, MIDI Cable

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.

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 (Musical Instrument Digital Interface) is a standard specification for networking 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.
