LTC Input signal indicated in CAL DISPLAY mode by I I 1 0000 The default timecode standard after powering up is defined by the non volatile stored settings made in the generator setup section 5 Detection of a different timecode standard takes one time 2 3 seconds A correctly setup default standard avoids this delay each time after powering up 4 MTC and USB input modes Digital Audio Workstations as well as lighting and show control software use MTC midi timecode for synchronisation mif 4 reads MTC to regenerate synchronised stable LTC and MTC timecode MTC timecode can be quite unstable and jittery caused by the latency of computer operating systems For this reason mif 4 makes use of slow and integrating sync algorithms If the unit receives an MTC full message it will stop and generate a short burst of stationary LTC timecode The unit repeats one LTC frame 8 times On the LED display there are DECIMAL POINTS to separate hours minutes seconds and frames 00 00 00 00 The rightmost decimal point to the right of the frame digits is used as aLOCKED indicator If the unit is in sync and outputs locked timecode this LOCKED indicator will light up In MTC or USB input modes the LOCKED threshold is lt 5ms in LTC mode lt 100uS If the incoming midi timecode is jumping or drifting away so that mif 4 is unable to follow the source it will display ERROR 01 in MTC mode or ERROR 02 in USB mode In this case a st
