Note that there is an error in the Service Manual.

Page 45 shows the SysClk @ 16.12MHz, it's actually 16MHz.

This is strange that the Word Clock is 31.25kHz, does this suggest that the Korg I3 has 31.25kHZ output and not (OMG) 44.1kHZ samples?

Who uses 31.25kHz anyway?....

Also note that the Audio PCM data is transferred with 18 bits not the usual 16bits! Interesting about the 31.25kHz samples though.
