9. re Triple DAT Software for example works fine with the midi cue mode q b 2 Because the MIF3 MIDI input accepts all these different cue modes and the MIDI output can output any midi cue mode the MIF3 is able to interface a Full message for example into a MMC locate command The match on the LTC side is called positional time code This is a continuous loop of one frame for cueing or locating The MIF3 detects positional time code and translates the positional frame into the selected midi cue mode message CB electronics SR 4 FEG v mod or Doremi V1 for example do produce positional LTC The MIF3 also translates incoming MTC Full messages MMC Locate commands or Quarter Loops into positional LTC ll DIP 4 Hold Off Value Most digital audio workstations can be synchronised with MTC midi time code to perform a trigger start of the playback function in combination with an external video or word clock reference to hold the system in continious sync Master time code e g from analog tape machines which ramps up and down can cause a continious offset error because the MTC trigger start has been executed to early The hold off value defines the number of passed frames until the MTC signal is output when the MIF3 is locked to the external time code source A hold off value of 50 frames dip 4 on will delay the synchronisation process for 2 seconds but also prevents too fast MTC trigger starts lll DIP 5 Calibration Displ
