Nuendo synchronization setup scenarios
Nuendo synchronization setup scenarios Purpose of this document This document contains various setup diagrams with short descriptions how to slave Nuendo to external time code in different scenarios and how to operate Nuendo as a 9-Pin slave. Only the most common scenarios are described here although other setups are possible too. For all cases below, the sync settings in the Nuendo Software are not described here. Please refer to the Nuendo User Manual for all software related settings.

Nuendo as a MIDI time code slave This is a simple setup for slaving Nuendo to a MIDI time code that is generated by an external device like a Tascam MX2424 or something similar. Any high quality MIDI interface can be used to pick up the provided MTC. Nuendo synchronization setup scenarios 3 of 9 November 2005
Nuendo as LTC time code slave In this scenario Nuendo is a time code slave to a tape machine or any other device that generates LTC. The Rosendahl WIF converts the incoming LTC (or VITC) to MTC and generates a word clock that follows the speed changes of the LTC signal up to +/- 10% of nominal speed.

Nuendo as 9-Pin Master, controlling a video deck using time code from 9-Pin This setup visualizes how to control a video deck like a Beta machine or a digital video player like a Doremi. For synchronization the time code is taken out of the 9-Pin stream. In this scenario Nuendo has to ask for the current time code position which - depending on the configuration - is not the most precise way for synchronization, even if it works fine for most applications. RS422 to RS232 converters are available from many industrial component manufactures ranging from $100 to $200. Since Apple Computers or newer PC notebooks don t provide any serial connector anymore it is required to use such an additional RS232 to USB converter. Much more elegant though is a 422USB interface from CB Electronics, which converts RS422 directly to USB. The CB Electronics 422USB unit is also available with an optional video sync in allowing for frame accurate transmission of the 9-pin commands.

Nuendo as 9-Pin Master, controlling a video deck using time code from separate LTC or VITC This setup is similar to the three previous setup examples above, only the time code is not provided by the 9-Pin stream but as separate VITC or LTC instead. For this scenario the Rosendahl WIF converts the incoming LTC or VITC to MTC and generates a word clock that follows the speed changes of the LTC signal up to +/- 10% of nominal speed. The MTC is picked up by any high quality MIDI interface that has to be defined as the time code source in the Nuendo Synchronization setup window. Some MDI or even audio interfaces already provide a LTC to MTC converter that can be used for time code synchronization. In any case there also has to be a stable clocking that is able to follow any time code jitter from the video deck. Rosendahl Nanosyncs for example is able to pick up a time code and to generate a word clock that follows the time code speed. Nuendo synchronization setup scenarios 8 of 9 November 2005
Nuendo as a 9-Pin Slave If Nuendo is used in more complex studio environments it may have to perform as a 9-Pin slave. For example you might want to have transport control, track arming, and synchronization operated from a large format mixing console with an integrated 9-Pin control panel. In the described scenario Nuendo acts as a recorder picking up the signals from the console. In this setup, CB Electronics P2MMC converts the 9-Pin commands from the console to MMC (MIDI Machine Control) that Nuendo can use for track arming and commands such as Edit in and Edit strobe. The time code is provided independently by the 9-Pin controller or an LTC distribution amplifier. Nuendo synchronization setup scenarios 9 of 9 November 2005
