Digital audio workstations as well as lighting and show control software make use of MTC midi timecode for synchronisation. The new mif4 provides professional interfacing to standard LTC (SMPTE) timecode. Rosendahl sync algorithms suppress timecode jitter and drop outs.


SOURCE = LTC read LTC (SMPTE) timecode, display and convert into MTC/USB midi time code and regenerate LTC (SMPTE) timecode.
SOURCE = MIDI read MTC from MIDI input, display and convert into LTC (SMPTE) and regenerate MTC/USB midi timecode.
SOURCE = USB read MTC from USB, display and convert into LTC (SMPTE) and regenerate MTC/USB midi timecode.
SOURCE = GEN the timecode generator can be set up and started manually or remote controlled by MMC midi machine control comands.
FPS timecode standards are automatically detected and displayed by the four FPS LEDs (24, 25, 30 Frames Per Second, DF is SMPTE Drop Frame standard).
DISPLAY = TC shows timecode in hours, minutes, seconds and frames.
DISPLAY = UB SMPTE user bits, 8 nibbles shown hexadecimal.
