Set "SMPTE/MTC Sync" to "Freewheel"
Sample-accurate synchronization not supported New 2/99!
Technical information on Cakewalk website New 2/99!
Digital audio programs sometimes include an option to continuously synchronize audio to incoming timecode (such as MTC or SMPTE), using software interpolation. This is a very handy feature when syncing to an analog tape deck. Essentially, it uses the rate of the incoming timecode to control the word clock of the audio.
However, when using the 1212 I/O and syncing to an ADAT-format digital multitrack, this feature should be disabled. The 1212 I/O provides continuous synchronization in hardware, through word clock synchronization. Using software-based continuous sync in addition to this will only serve to degrade the audio.
In Cakewalk Pro Audio, the sync mode is controlled by the parameter "SMPTE/MTC Sync," located in Settings->Audio Options->Advanced. To turn off software-based continuous sync, set "SMPTE/MTC Sync" to "Freewheel."

Cakewalk does not currently offer support for any form of sample-accurate synchronization, including that offered by the 1212 I/O. Hopefully, this capability will be added in a future release of Cakewalk.
