When the Freewheel timer is is disabled, Mitti will use Jam-Sync. Jam-Sync means whenever the incoming timecode signal considered to be lost, Mitti will switch to its internal SMPTE clock to continue playback and will automatically switch back to use the incoming timecode signal when it is available again.
When Jam-Sync is activated, Mitti's play button will show an exclamation mark (!).
This feature is useful when handling dropped MTC/LTC signals in production environment.
