it is first the Track synchronization which was added.
To configure it, you first need to define your MusicMaster settings. Go to the general settings, section Folder/Libraries and click on the 'Scheduler Automation...' button.
In 'Scheduler Automation' dialog enable the 'Use Music Master Nexus' checkbox and click on the ' Music Master Nexus...' button.
Here you need to specify your MusicMaster settings…
Beside the address etc. the most important field is the MusicMaster CutID – which is the unique ID in MusicMaster. By default 101 is used.
Plus you need to define the Field Mapping. I.e. remove all fields you don’t need or have in Music Master – plus you MUST specify their related MusicMaster field IDs!
If you have questions about the field IDs etc. you can consult you MusicMaster support – here it is actually the mapping which ProppFrexx meta data field should be mapped to which MusicMaster field id.
It is an xml config file – so don’t mess the xml format

(ignore the Pubish buttons for now – they have no function yet!)
Once this is defined, you can go to your ProppFrexx Media Libraries… and sync them with MusicMaster.
When you now right-click on a media library and select ‘Export…’ you can now choose ‘MusicMaster Nexus’ and click on the Export button.
The MediaLibrary will now export/synchronize with MusicMaster Nexus (create or update songs in Nexus).
The speed is (in my mind) disappointing – even if MusicMaster told me, that the speed is very good and as expected.
So please do not blame me – this is limited by the MusicMaster API resp. Nexus database speed!
Please test this, if this is working fine for you.
MusicMaster told me, that most users still publish and import the schedule via the normal log files (as you do now).
