For this reason, when using the 1212 I/O with some Sound Manager
programs, you may want to mute the Auto-Routing Mode by pressing the
Mute All button in the 1212 I/O Utility.
Whenever you edit the current settings in the 1212 I/O Utility, the 1212 I/O
remembers these settings, and continues to use them for the Auto-Routing
Mode as long as the computer is on. On the next startup, it will again be
restored to the settings in the Preferences file (in the MacOS) or the System
Registry (in Windows 95).
Routing from S/PDIF In to ADAT Out
You can use the 1212 I/O Utility to transfer digital audio from a S/PDIF
device, such as a DAT machine, synth, sampler, or external A/D converter,
to an ADAT-compatible multitrack recorder.

For more information, please see "Setting the word clock source in digital
audio software" on page 16.
If you are using the Alesis BRC, read the instructions under "Using the
Alesis BRC: 1212 I/O output to ADAT input," on page 36.
This procedure makes the ADAT system sync to the word clock of the
S/PDIF source, as translated into ADAT optical output through the
1212 I/O. If the ADAT system is not set to sync to an external word clock, it
will not interpret the incoming audio data correctly, and you'll hear
clicking or other nasty audio artifacts.

When the BRC is connected, it supplies the word clock to the ADAT
system. Without the BRC, the clock is derived from the ADAT optical I/O,
and so an explicit word clock connection is unnecessary.
Routing from ADAT In to S/PDIF Out
Routing from ADAT in to S/PDIF out is slightly different from the other
way around.

Since original ADATs used the pitch control to choose between 48kHz and
44.1kHz, the 1212 I/O cannot be sure of the sample rate of ADAT input.
Korg 1212 I/O
Set inputs S/PDIF L and S/PDIF R to the desired ADAT output
channels.
Set the Clock Source to "S/PDIF•ClockIn."
Set the ADAT system to sync to the external word clock.
If you are using the Alesis BRC, connect the Word Clock output of
the 1212 I/O to the 48kHz In of the BRC, and then follow the
instructions under "Using the Alesis BRC: 1212 I/O output to ADAT
input," on page 36.
Set the desired ADAT inputs to the S/PDIF L and S/PDIF R outputs.
Set the 1212 I/O's Sample Rate to match that of the ADAT system.
